sneak 4adeeae1db Add Secure Enclave unlocker for hardware-backed secret protection 
Adds a new "secure-enclave" unlocker type that stores the vault's
long-term private key encrypted by a non-exportable P-256 key held
in the Secure Enclave hardware. Decryption (ECDH) is performed
inside the SE; the key never leaves the hardware.

Uses CryptoTokenKit identities created via sc_auth, which allows
SE access from unsigned binaries without Apple Developer Program
membership. ECIES (X963SHA256 + AES-GCM) handles encryption and
decryption through Security.framework.

New package internal/macse/ provides the CGo bridge to
Security.framework for SE key creation, ECIES encrypt/decrypt,
and key deletion. The SE unlocker directly encrypts the vault
long-term key (no intermediate age keypair).

## Go-Specific Guidelines
1. **No `panic`, `log.Fatal`, or `os.Exit` in library code.** Always propagate errors via return values.
2. **Constructors return `(*T, error)`, not just `*T`.** Callers must handle errors, not crash.
3. **Wrap errors** with `fmt.Errorf("context: %w", err)` for debuggability.
4. **Never modify linter config** (`.golangci.yml`) to suppress findings. Fix the code.
5. **All PRs must pass `make check` with zero failures.** No exceptions, no "pre-existing issue" excuses.
6. **Pin external dependencies by commit hash**, not mutable tags.

## Entrypoints
This repository adheres to the
[Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
standard: normalized scripts in `script/` are the entrypoints for the
development workflow, and the Makefile targets are thin shims that call
them. We provide:
- `script/bootstrap` — install all dependencies (Go, Go module
download), idempotently; golangci-lint is not installed, it runs in
docker
- `script/setup` — make a fresh clone ready for development: runs
`script/bootstrap`, then `script/install-precommit`
- `script/projectname` — output the project name (`secret`); used by
other scripts such as `script/docker`
- `script/build` — build the `secret` binary into the repo root, stamping
the version (`VERSION` from the environment, else `git describe`) and
the git commit
- `script/test` — run `go vet` and the test suite (verbose rerun on
failure)
- `script/lint` — run `golangci-lint` in docker only: builds
`Dockerfile.lint`, where the linter is a build step that runs on every
call, also on an unchanged tree
- `script/fmt` — format all Go code (writes)
- `script/fmt-check` — check formatting without writing
- `script/check` — run `script/test`, `script/lint`, and
`script/fmt-check`
- `script/docker` — build the Docker image tagged with the project name
- `script/cibuild` — CI entrypoint: `docker build --ulimit
memlock=-1:-1 .` (memguard needs mlock; the Dockerfile runs the
checks), with a new `CHECK_EPOCH` build argument on every run so the
checks run again on an unchanged tree
- `script/precommit` — pre-commit checks: `go mod tidy` verification,
then `script/check`
- `script/install-precommit` — install the git pre-commit hook that
runs `script/precommit`
## Features
- **Multiple Authentication Methods**: Supports passphrase, PGP, macOS Keychain, and Secure Enclave unlockers
- **Multiple Authentication Methods**: Supports passphrase, PGP, and macOS Keychain unlockers
- **Vault Isolation**: Complete separation between different vaults
- **Per-Secret Encryption**: Each secret has its own encryption key
- **BIP39 Mnemonic Support**: Keyless operation using mnemonic phrases

title: Repository Policies
last_modified: 2026-07-06

This document covers repository structure, tooling, and workflow standards. Code
style conventions are in separate documents:
- [Code Styleguide](https://git.eeqj.de/sneak/prompts/raw/branch/main/prompts/CODE_STYLEGUIDE.md)
(general, bash, Docker)
- [Go](https://git.eeqj.de/sneak/prompts/raw/branch/main/prompts/CODE_STYLEGUIDE_GO.md)
- [JavaScript](https://git.eeqj.de/sneak/prompts/raw/branch/main/prompts/CODE_STYLEGUIDE_JS.md)

- [Go HTTP Server Conventions](https://git.eeqj.de/sneak/prompts/raw/branch/main/prompts/GO_HTTP_SERVER_CONVENTIONS.md)
---
- Cross-project documentation (such as this file) must include
`last_modified: YYYY-MM-DD` in the YAML front matter so it can be kept in sync
with the authoritative source as policies evolve.
- **ALL external references must be pinned by cryptographic hash.** This
includes Docker base images, Go modules, npm packages, GitHub Actions, and
anything else fetched from a remote source. Version tags (`@v4`, `@latest`,
`:3.21`, etc.) are server-mutable and therefore remote code execution
vulnerabilities. The ONLY acceptable way to reference an external dependency
is by its content hash (Docker `@sha256:...`, Go module hash in `go.sum`, npm
integrity hash in lockfile, GitHub Actions `@<commit-sha>`). No exceptions.
This also means never `curl | bash` to install tools like pyenv, nvm, rustup,
etc. Instead, download a specific release archive from GitHub, verify its hash
(hardcoded in the Dockerfile or script), and only then install. Unverified
install scripts are arbitrary remote code execution. This is the single most
important rule in this document. Double-check every external reference in
every file before committing. There are zero exceptions to this rule.
- Every repo with software must have a root `Makefile` with these targets:
`make bootstrap`, `make setup`, `make test`, `make lint`, `make fmt` (writes),
`make fmt-check` (read-only), `make check` (runs `test`, `lint`, `fmt-check`),
`make docker`, and `make hooks` (installs pre-commit hook). A model Makefile
is at `https://git.eeqj.de/sneak/prompts/raw/branch/main/Makefile`.
- Repos follow the
[Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
pattern: the implementation of each Makefile target lives in an executable
script in `script/` (`script/bootstrap`, `script/setup`, `script/test`,
`script/lint`, `script/fmt`, `script/fmt-check`, `script/check`,
`script/docker`), and the Makefile targets are thin shims that call them. The
scripts must be POSIX sh (`#!/bin/sh`, `set -eu`, no bashisms) so they run in
minimal containers (e.g. alpine images have no bash); locate the repo root
with `$(cd "$(dirname "$0")/.." && pwd -P)` and `cd` there before acting. From
the standard's canonical set we use `bootstrap`, `setup` (make the repo ready
for development after a fresh clone: runs `bootstrap`, then
`install-precommit`, plus any repo-specific initialization), `test`, and
`cibuild`. `script/bootstrap` installs all dependencies idempotently and
assumes nothing is present: base tools come from nix, apt, brew, or apk
(detected in that order; apt runs noninteractive). For node it uses the
installed node if present; otherwise it installs a PINNED node version via
nvm, first installing nvm itself if missing — from a hash-verified GitHub
release archive (never `curl | sh`), with bash installed as an explicit
prerequisite since nvm requires bash. yarn is then pinned via
`corepack prepare yarn@<version> --activate`. Never install "latest" or "lts";
always exact versions. `script/cibuild` runs the CI build: it changes to the
repo root and runs `docker build .`; the Gitea workflow calls it. Four further
scripts are our own extensions to the standard: `script/check` runs
`script/test`, `script/lint`, and `script/fmt-check`; `script/precommit` is
what the git pre-commit hook runs, and it calls `script/check`;
`script/install-precommit` installs the git pre-commit hook (the `make hooks`
target shims to it); and `script/projectname` (literally that filename) simply
outputs the project's name. Scripts that need the name call
`script/projectname` — e.g. `script/docker` assembles its image tag from it —
so those scripts stay byte-identical across all repos. Repo-type-specific
pre-commit extras (e.g. `go mod tidy` verification in Go repos) belong in
`script/precommit`, not in the hook itself. Model scripts are at
`https://git.eeqj.de/sneak/prompts/raw/branch/main/script/<name>`. The README
must document the provided scripts in an **Entrypoints** section (see the
README requirements below).
- Always use Makefile targets (`make fmt`, `make test`, `make lint`, etc.)
instead of invoking the underlying tools directly. The Makefile is the single
source of truth for how these operations are run.
- The Makefile is authoritative documentation for how the repo is used. Beyond
the required targets above, it should have targets for every common operation:
running a local development server (`make run`, `make dev`), re-initializing
or migrating the database (`make db-reset`, `make migrate`), building
artifacts (`make build`), generating code, seeding data, or anything else a
developer would do regularly. If someone checks out the repo and types
`make<tab>`, they should see every meaningful operation available. A new
contributor should be able to understand the entire development workflow by
reading the Makefile.
- Every repo should have a `Dockerfile`. All Dockerfiles must run `make check`
as a build step so the build fails if the branch is not green. For non-server
repos, the Dockerfile should bring up a development environment and run
`make check`. For server repos, `make check` should run as an early build
stage before the final image is assembled. Dockerfiles install development
prerequisites by running `script/bootstrap` rather than duplicating installs
inline; COPY `script/` and the dependency manifests (`package.json` +
`yarn.lock`, `go.mod` + `go.sum`, etc.) before running it so the bootstrap
layer stays cached until dependencies change.
- **Dockerfiles must use a separate lint stage for fail-fast feedback.** Go
repos use a multistage build where linting runs in an independent stage based
on the `golangci/golangci-lint` image (pinned by hash). This stage runs
`make fmt-check` and `make lint` before the full build begins. The build stage
then declares an explicit dependency on the lint stage via
`COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
linting before proceeding to compilation and tests. This ensures lint failures
surface in seconds rather than minutes, without blocking on dependency
download or compilation in the build stage.
The standard pattern for a Go repo Dockerfile is:
```dockerfile
# Lint stage — fast feedback on formatting and lint issues
# golangci/golangci-lint:v2.x.x, YYYY-MM-DD
FROM golangci/golangci-lint@sha256:... AS lint
WORKDIR /src
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN make fmt-check
RUN make lint
# Build stage
# golang:1.x-alpine, YYYY-MM-DD
FROM golang@sha256:... AS builder
WORKDIR /src
# Force BuildKit to run the lint stage before proceeding
COPY --from=lint /src/go.sum /dev/null
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN make test
ARG VERSION=dev
RUN CGO_ENABLED=0 go build -trimpath \
-ldflags="-s -w -X main.Version=${VERSION}" \
-o /app ./cmd/app/
# Runtime stage
FROM alpine@sha256:...
COPY --from=builder /app /usr/local/bin/app
ENTRYPOINT ["app"]
```
Key points:
- The lint stage uses the `golangci/golangci-lint` image directly (it
includes both Go and the linter), so there is no need to install the
linter separately.
- `COPY --from=lint /src/go.sum /dev/null` is a no-op file copy that creates
a stage dependency. BuildKit runs stages in parallel by default; without
this line, the build stage would not wait for lint to finish and a lint
failure might not fail the overall build.
- If the project uses `//go:embed` directives that reference build artifacts
(e.g. a web frontend compiled in a separate stage), the lint stage must
create placeholder files so the embed directives resolve. Example:
`RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
The lint stage should not depend on the actual build output — it exists to
fail fast.
- If the project requires CGO or system libraries for linting (e.g.
`vips-dev`), install them in the lint stage with `apk add`.
- The build stage runs `make test` after compilation setup. Tests run in the
build stage, not the lint stage, because they may require compiled
artifacts or heavier dependencies.
- Every repo should have a Gitea Actions workflow (`.gitea/workflows/`) that
runs `script/cibuild` (which runs `docker build .`) on push. Since the
Dockerfile already runs `make check`, a successful build implies all checks
pass.
- Use platform-standard formatters: `black` for Python, `prettier` for
JS/CSS/Markdown/HTML, `go fmt` for Go. Always use default configuration with
two exceptions: four-space indents (except Go), and `proseWrap: always` for
Markdown (hard-wrap at 80 columns). Documentation and writing repos (Markdown,
HTML, CSS) should also have `.prettierrc` and `.prettierignore`.
- Pre-commit hook: runs `script/precommit`, which calls `script/check`. If local
testing is not possible in the repo, `script/precommit` may skip `script/test`
and run only `script/lint` and `script/fmt-check`. The hook is installed by
`script/install-precommit`; the Makefile must provide a `make hooks` target
that shims to it.
- All repos with software must have tests that run via the platform-standard
test framework (`go test`, `pytest`, `jest`/`vitest`, etc.). If no meaningful
tests exist yet, add the most minimal test possible — e.g. importing the
module under test to verify it compiles/parses. There is no excuse for
`make test` to be a no-op.
- `make test` must complete in under 20 seconds. Add a 30-second timeout in the
Makefile.
- **`make test` should use the conditional verbose rerun pattern.** Run tests
without `-v` (verbose) first. If tests fail, automatically rerun with `-v` to
show full output. This keeps CI logs and `docker build` output clean on
success (just package/suite summaries) while providing full diagnostic detail
on failure (every test case, every assertion). The general shell pattern:
```makefile
test:
@<test-command> || \
{ echo "--- Rerunning with -v for details ---"; \
<test-command-with-v>; exit 1; }
```
Go example:
```makefile
test:
@go test -timeout 30s -race -cover ./... || \
{ echo "--- Rerunning with -v for details ---"; \
go test -timeout 30s -race -v ./...; exit 1; }
```
Python example:
```makefile
test:
@python -m pytest || \
{ echo "--- Rerunning with -v for details ---"; \
python -m pytest -v; exit 1; }
```
The `exit 1` ensures the target always fails after a rerun — the first run
already proved the tests are broken, so the build must not pass even if a
flaky test happens to succeed on the second attempt. The rerun exists solely
for diagnostic output.
- Docker builds must complete in under 5 minutes.
- `make check` must not modify any files in the repo. Tests may use temporary
directories.
- `main` must always pass `make check`, no exceptions.
- Never commit secrets. `.env` files, credentials, API keys, and private keys
must be in `.gitignore`. No exceptions.
- `.gitignore` should be comprehensive from the start: OS files (`.DS_Store`),
editor files (`.swp`, `*~`), language build artifacts, and `node_modules/`.
Fetch the standard `.gitignore` from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.gitignore` when setting up
a new repo.
- **No build artifacts in version control.** Code-derived data (compiled
bundles, minified output, generated assets) must never be committed to the
repository if it can be avoided. The build process (e.g. Dockerfile, Makefile)
should generate these at build time. Notable exception: Go protobuf generated
files (`.pb.go`) ARE committed because repos need to work with `go get`, which
downloads code but does not execute code generation.
- Never use `git add -A` or `git add .`. Always stage files explicitly by name.
- Never force-push to `main`.
- Make all changes on a feature branch. You can do whatever you want on a
feature branch.
- `.golangci.yml` is standardized and must _NEVER_ be modified by an agent, only
manually by the user. Fetch from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.golangci.yml`.
- When pinning images or packages by hash, add a comment above the reference
with the version and date (YYYY-MM-DD).
- Use `yarn`, not `npm`.
- Write all dates as YYYY-MM-DD (ISO 8601).
- Simple projects should be configured with environment variables.
- Dockerized web services listen on port 8080 by default, overridable with
`PORT`.
- **HTTP/web services must be hardened for production internet exposure before
tagging 1.0.** This means full compliance with security best practices
including, without limitation, all of the following:
- **Security headers** on every response:
- `Strict-Transport-Security` (HSTS) with `max-age` of at least one year
and `includeSubDomains`.
- `Content-Security-Policy` (CSP) with a restrictive default policy
(`default-src 'self'` as a baseline, tightened per-resource as
needed). Never use `unsafe-inline` or `unsafe-eval` unless
unavoidable, and document the reason.
- `X-Frame-Options: DENY` (or `SAMEORIGIN` if framing is required).
Prefer the `frame-ancestors` CSP directive as the primary control.
- `X-Content-Type-Options: nosniff`.
- `Referrer-Policy: strict-origin-when-cross-origin` (or stricter).
- `Permissions-Policy` restricting access to browser features the
application does not use (camera, microphone, geolocation, etc.).
- **Request and response limits:**
- Maximum request body size enforced on all endpoints (e.g. Go
`http.MaxBytesReader`). Choose a sane default per-route; never accept
unbounded input.
- Maximum response body size where applicable (e.g. paginated APIs).
- `ReadTimeout` and `ReadHeaderTimeout` on the `http.Server` to defend
against slowloris attacks.
- `WriteTimeout` on the `http.Server`.
- `IdleTimeout` on the `http.Server`.
- Per-handler execution time limits via `context.WithTimeout` or
chi/stdlib `middleware.Timeout`.
- **Authentication and session security:**
- Rate limiting on password-based authentication endpoints. API keys are
high-entropy and not susceptible to brute force, so they are exempt.
- CSRF tokens on all state-mutating HTML forms. API endpoints
authenticated via `Authorization` header (Bearer token, API key) are
exempt because the browser does not attach these automatically.
- Passwords stored using bcrypt, scrypt, or argon2 — never plain-text,
MD5, or SHA.
- Session cookies set with `HttpOnly`, `Secure`, and `SameSite=Lax` (or
`Strict`) attributes.
- **Reverse proxy awareness:**
- True client IP detection when behind a reverse proxy
(`X-Forwarded-For`, `X-Real-IP`). The application must accept
forwarded headers only from a configured set of trusted proxy
addresses — never trust `X-Forwarded-For` unconditionally.
- **CORS:**
- Authenticated endpoints must restrict `Access-Control-Allow-Origin` to
an explicit allowlist of known origins. Wildcard (`*`) is acceptable
only for public, unauthenticated read-only APIs.
- **Error handling:**
- Internal errors must never leak stack traces, SQL queries, file paths,
or other implementation details to the client. Return generic error
messages in production; detailed errors only when `DEBUG` is enabled.
- **TLS:**
- Services never terminate TLS directly. They are always deployed behind
a TLS-terminating reverse proxy. The service itself listens on plain
HTTP. However, HSTS headers and `Secure` cookie flags must still be
set by the application so that the browser enforces HTTPS end-to-end.
This list is non-exhaustive. Apply defense-in-depth: if a standard security
hardening measure exists for HTTP services and is not listed here, it is
still expected. When in doubt, harden.
- `README.md` is the primary documentation. Required sections:
- **Description**: First line must include the project name, purpose,
category (web server, SPA, CLI tool, etc.), license, and author. Example:
"µPaaS is an MIT-licensed Go web application by @sneak that receives
git-frontend webhooks and deploys applications via Docker in realtime."
- **Getting Started**: Copy-pasteable install/usage code block.
- **Entrypoints**: Opens by stating that the repo adheres to the
[Scripts to Rule Them All](https://github.com/github/scripts-to-rule-them-all)
standard (with that link), then documents each provided `script/`
entrypoint and its purpose.
- **Rationale**: Why does this exist?
- **Design**: How is the program structured?
- **TODO**: Update meticulously, even between commits. When planning, put
the todo list in the README so a new agent can pick up where the last one
left off.
- **License**: MIT, GPL, or WTFPL. Ask the user for new projects. Include a
`LICENSE` file in the repo root and a License section in the README.
- **Author**: [@sneak](https://sneak.berlin).
- First commit of a new repo should contain only `README.md`.
- Go module root: `sneak.berlin/go/<name>`. Always run `go mod tidy` before
committing.
- Use SemVer.
- Database migrations live in `internal/db/migrations/` and must be embedded in
the binary.
- `000_migration.sql` — contains ONLY the creation of the migrations
tracking table itself. Nothing else.
- `001_schema.sql` — the full application schema.
- **Pre-1.0.0:** never add additional migration files (002, 003, etc.).
There is no installed base to migrate. Edit `001_schema.sql` directly.
- **Post-1.0.0:** add new numbered migration files for each schema change.
Never edit existing migrations after release.
- All repos should have an `.editorconfig` enforcing the project's indentation
settings.
- Avoid putting files in the repo root unless necessary. Root should contain
only project-level config files (`README.md`, `Makefile`, `Dockerfile`,
`LICENSE`, `.gitignore`, `.editorconfig`, `REPO_POLICIES.md`, and
language-specific config). Everything else goes in a subdirectory. Canonical
subdirectory names:
- `bin/` — executable scripts and tools
- `cmd/` — Go command entrypoints
- `configs/` — configuration templates and examples
- `deploy/` — deployment manifests (k8s, compose, terraform)
- `docs/` — documentation and markdown (README.md stays in root)
- `internal/` — Go internal packages
- `internal/db/migrations/` — database migrations
- `pkg/` — Go library packages
- `share/` — systemd units, data files
- `static/` — static assets (images, fonts, etc.)
- `web/` — web frontend source
- When setting up a new repo, files from the `prompts` repo may be used as
templates. Fetch them from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/<path>`.
- New repos must contain at minimum:
- `README.md`, `.git`, `.gitignore`, `.editorconfig`
- `LICENSE`, `REPO_POLICIES.md` (copy from the `prompts` repo)
- `Makefile`
- `script/` entrypoints (`bootstrap`, `setup`, `projectname`, `test`,
`lint`, `fmt`, `fmt-check`, `check`, `docker`, `cibuild`, `precommit`,
`install-precommit`)
- `Dockerfile`, `.dockerignore`
- `.gitea/workflows/check.yml`
- Go: `go.mod`, `go.sum`, `.golangci.yml`
- JS: `package.json`, `yarn.lock`, `.prettierrc`, `.prettierignore`
- Python: `pyproject.toml`

This document outlines the bugs, issues, and improvements that need to be
addressed before the 1.0 release of the secret manager. Items are
prioritized from most critical (top) to least critical (bottom).
# Status
## CRITICAL BLOCKERS FOR 1.0 RELEASE
pre-1.0. No git tags. TODO.md carries open 1.0 security blockers. Work in
flight on branch secure-enclave-unlocker (clean tree as of 2026-07-06).
### Command Injection Vulnerabilities
- [ ] **1. PGP command injection risk**: `internal/secret/pgpunlocker.go:323-327` - GPG key IDs passed directly to exec.Command without proper escaping
- [ ] **2. Keychain command injection risk**: `internal/secret/keychainunlocker.go:472-476` - data.String() passed to security command without escaping
# Next Step
### Memory Security Critical Issues
- [ ] **3. Plain text passphrase in memory**: `internal/secret/keychainunlocker.go:342,393-396` - KeychainData struct stores AgePrivKeyPassphrase as unprotected string
- [ ] **4. Sensitive string conversions**: `internal/secret/keychainunlocker.go:356`, `internal/secret/pgpunlocker.go:256`, `internal/secret/version.go:155` - Age identity .String() creates unprotected copies
Bring the repo into policy compliance in one commit:
### Race Conditions (Data Corruption Risk)
- [ ] **5. No file locking mechanism**: `internal/vault/secrets.go:142-176` - Multiple concurrent operations can corrupt vault state
- [ ] **6. Non-atomic file operations**: Various locations - Interrupted writes leave vault inconsistent
- Add fmt-check and hooks targets to the Makefile (test/lint/fmt/check/
docker already exist).
- Add REPO_POLICIES.md and .editorconfig.
- Add .gitea/workflows/check.yml running make check.
- Verify Dockerfile base images are pinned by sha256.
### Input Validation Vulnerabilities
- [ ] **7. Path traversal risk**: `internal/vault/secrets.go:75-99` - Secret names allow dots which could enable traversal attacks with encoding
- [ ] **8. Missing size limits**: `internal/vault/secrets.go:102` - No maximum secret size allows DoS via memory exhaustion
# Completed Steps
### Timing Attack Vulnerabilities
- [ ] **9. Non-constant-time passphrase comparison**: `internal/cli/init.go:209-216` - bytes.Equal() vulnerable to timing attacks
- [ ] **10. Non-constant-time key validation**: `internal/vault/vault.go:95-100` - Public key comparison leaks timing information
- 2026-10-04: `SB_SECRET_MNEMONIC` and `SB_UNLOCK_PASSPHRASE` are read once
per command, in its `RunE`, into locked buffers on the CLI `Instance`, and
unset at once, so that no program the command runs, `gpg` included,
inherits them (https://git.eeqj.de/sneak/secret/issues/60). Nothing below
the command reads the environment; the buffers are passed down:
`vault.CreateVault` takes the mnemonic (nil for none), a `Vault` derives its
long-term key from its `Mnemonic` and gives its `UnlockPassphrase` to a
passphrase unlocker, and the PGP, keychain and Secure Enclave unlocker
constructors take both. `CreatePGPUnlocker` sets both on the vault it
loads, through `SetMnemonic` and `SetUnlockPassphrase`, now part of
`VaultInterface`, before calling its `GetOrDeriveLongTermKey`. `init` and
`vault create` no longer put the mnemonic into the environment. Unsetting
erases nothing: the starting environment (`/proc/<pid>/environ`) and
memory still hold the value. The README warns against both variables.
- 2026-10-04: `secret unlocker add pgp` works on Linux
(https://git.eeqj.de/sneak/secret/issues/88). `CreatePGPUnlocker` gets
the vault's long-term key as adding a passphrase unlocker does, with the
vault's `GetOrDeriveLongTermKey`, now part of `VaultInterface`: from the
mnemonic, checked against the vault, or else from the current unlocker.
Before, it used the keychain unlocker's helper, which on every platform
but macOS always failed. A test adds a PGP unlocker for a throwaway GPG
key, getting the long-term key once from the mnemonic and once from a
passphrase unlocker, and reads a secret through the new unlocker.
- 2026-10-04: A vault name may use only lowercase ASCII letters, digits,
`.`, `-` and `_`, and must not be empty, `.` or `..`
(https://git.eeqj.de/sneak/secret/issues/68); the error and `README.md`
state the rule. `vault create`, `vault import`, `vault select`,
`vault remove`, both vault names of `mv` and shell completion of a
`vault:secret` argument check the name as typed with
`vault.ValidateVaultName` before building any path from it. Before,
`vault import ..` wrote a long-term key and an unlocker into the state
directory itself, and `vault select ..` made that the current vault.
- 2026-10-04: `script/cibuild` runs the checks again on an unchanged
tree (https://git.eeqj.de/sneak/secret/issues/54). It passes the
current time as the `CHECK_EPOCH` build argument, which both the lint
and the build stage of the `Dockerfile` declare after their module
download, so the `RUN` steps below the argument run again on each
build while the base images and module downloads stay cached. Before,
a second run on the same tree took every check from the build cache
and reported success having run nothing.
- 2026-10-04: A failed unlocker add no longer leaves a partial unlocker
directory (https://git.eeqj.de/sneak/secret/issues/48).
`secret unlocker add pgp` resolves the GPG key's fingerprint once, for
its duplicate check, and passes it to `CreatePGPUnlocker` to record.
`CreatePGPUnlocker` and `CreateKeychainUnlocker` get the long-term key
and encrypt everything before writing anything. All four unlocker
types write their files through `secret.WriteDir`: a new unlocker is
built in a temporary directory, renamed into place when complete and
removed on a failure. One added under the directory name of an
existing unlocker is still written into that directory in place
(https://git.eeqj.de/sneak/secret/issues/71).
- 2026-10-04: `secret unlocker select` and `secret unlocker remove`
skip, with the warning `unlocker list` gives, an unlocker directory
whose metadata file cannot be checked for, read or parsed, instead of
failing when it sorts before the unlocker asked for. Such a directory,
or one without a metadata file, is removed by its directory name, the
name the warning gives; only the directory is removed, since its type
is unknown. Removing one whose metadata file is missing or corrupt
never counts as removing the last unlocker. Removing one whose metadata
file cannot be checked for or read always does, since it may be the
only working unlocker, so in a vault with secrets it needs `--force`.
- 2026-10-04: A failed command prints its error once, without the usage
text after it (https://git.eeqj.de/sneak/secret/issues/41). Usage is
still printed for a command called wrongly: wrong number of arguments,
unknown flag, bad flag value, missing required flag, or flags that
break a flag group (mutually exclusive, required together, one
required). The root command's `PersistentPreRunE` turns usage off.
Cobra checks arguments and flag values before that hook but required
flags and flag groups only after it, so the hook checks those two
first. Root `SilenceUsage` would have hidden usage for all of these.
- 2026-10-04: `secret get` keeps the secret in locked memory until it
writes it out (https://git.eeqj.de/sneak/secret/issues/37):
`Vault.GetSecret` and `Vault.GetSecretVersion` return a
`*memguard.LockedBuffer`, which every caller destroys, and `secret get`
writes its bytes straight to stdout, still with no trailing newline.
Before, the value was copied into ordinary memory that nothing wiped,
and `get --version` also wrote it to the debug log.
- 2026-10-04: The `Makefile` no longer sets `DOCKER_HOST`, so its docker
targets use the local docker daemon, or whatever `DOCKER_HOST` the
environment sets. `make build` calls the new `script/build`, which
stamps the version (`VERSION` from the environment, else
`git describe`) and the git commit as before. `build`, `clean`,
`install` and `docker-run` are in `.PHONY`; `make install` depends on
`build`. The `vet` target is gone: `script/test` runs `go vet` first.
- 2026-10-04: `.gitignore` is the org's standard file, which ignores
`.env`, `.env.*`, `*.pem` and `*.key` and editor and OS files, plus
this repo's `/secret`, `*.log`, `*.test` and `settings.local.json`
(https://git.eeqj.de/sneak/secret/issues/40). `.dockerignore` also
leaves out `node_modules`; `.git` stays in the build context for the
version stamp.
- 2026-10-04: `secret init` refuses when the default vault exists, and
`secret vault create NAME` when `NAME` does, with "vault NAME already
exists", before writing anything. The check is in `vault.CreateVault`,
which both commands call while holding the state directory lock, so two
creates of one vault at once cannot both pass the check. Before, either
command replaced the vault's metadata, passphrase unlocker and
`longterm.age`, so none of its secrets could be decrypted any more. Both
commands now ask for the unlocker passphrase before creating the vault,
so one stopped at that prompt leaves no vault behind.
- 2026-10-04: The `internal/cli` tests are back to about their time
before the state directory lock
(https://git.eeqj.de/sneak/secret/issues/80). The test that each
changing command waits for the lock releases it as soon as it sees the
command waiting there, instead of after a fixed 100 ms. The two vaults
with passphrase unlockers that the path and move tests start from are
made once and copied for each test.
- 2026-10-04: `secret mv` rejects a move whose destination is the source
under another name, such as `foo` for `Foo` on a case-insensitive
filesystem (the macOS default) or a name reached through a symbolic
link, before changing anything, with or without `--force`, within a
vault and between vaults; before, `--force` removed the destination and
so deleted the secret. A rename that changes only letter case works on a
case-sensitive filesystem as before.
- 2026-10-04: Lint runs only in docker: `script/lint` builds
`Dockerfile.lint`, where golangci-lint is a build step rebuilt on
every run (`--no-cache-filter`), so an unchanged tree is linted too;
the module download stays cached. `script/bootstrap` no longer
installs golangci-lint, and the `Dockerfile` lint stage calls it
directly instead of `make lint`. `golangci-lint config verify` is not
run: it fetches its schema live over unpinned HTTPS.
- 2026-10-04: A PGP unlocker whose metadata has no usable GPG key ID
no longer panics: `GetID()` warns with the unlocker's directory and
returns `pgp-unknown`. `ListUnlockers` skips, with a warning, an
unlocker whose metadata file cannot be checked for, read or parsed
instead of failing, so `secret unlocker list` still lists the others;
the listing's ID lookup no longer warns about that directory again.
- 2026-10-03: `secret mv` rejects a move whose destination is the
source (`mv --force x x`, `mv --force work:x work:`, or an empty
destination, which defaults to the source name) before changing
anything; before, `--force` removed the destination first and so
deleted the secret. Every vault name given with `vault:` must be one
of the existing vaults by exact name, so `work:x work/:x` is rejected
instead of being taken for a move between two vaults. A move within a
named vault no longer makes that vault the current one, whether it
succeeds or fails.
- 2026-10-03: Commands that change the state directory hold one lock
(`flock` on `lock` in the state directory; a mutex on the in-memory
test filesystem), so concurrent commands no longer lose versions or
race on the current pointers. Every file is written through
`secret.WriteFileAtomic` (temporary file, sync, rename), so no file
is ever half-written and `current`, `currentvault` and
`current-unlocker` never go missing. New versions, new secrets and
cross-vault copies are built in a temporary directory and renamed
into place, and removals rename out of the way first, so a version
or secret is never half-added and never half-removed. An
interrupted command can still leave:
- a broken unlocker, when it was replacing one: an unlocker added
under the directory name of an existing one is rewritten file by
file. That happens to a passphrase unlocker added to a vault that
has one, and to a PGP, keychain or Secure Enclave unlocker added
on the same host and day as another of its type
(https://git.eeqj.de/sneak/secret/issues/71);
- from `init` or `vault create` killed after the passphrase prompt
but before the unlocker is written, a vault with no unlocker,
which `vault create` has already made the current vault;
- data under a `.tmp-` name in the state directory: a secret,
version or unlocker being added, or the secret, version, unlocker
or vault being removed, encrypted keys included. Nothing deletes
it; it must be deleted by hand
(https://git.eeqj.de/sneak/secret/issues/75).
- 2026-10-03: The checks run before changing a vault now stop with an
error naming the path and cause when they cannot read what they
inspect, instead of reading the failure as "nothing there": the
duplicate check before `unlocker add pgp` (an unreadable
`unlockers.d` or unlocker metadata file), the secret count that
guards removing the last unlocker and removing a vault, and the
existing long-term key check before `vault import`.
- 2026-10-03: `version rm`, `version promote` and `get --version`
accept a version only if it is one of the versions `version list`
lists for that secret, compared as typed before any path is built
(`secret.VersionExists`), and touch nothing otherwise. An empty
`--version` is rejected instead of meaning the current version.
Before, `secret version rm x ../../..` deleted the whole vault,
`secret version rm x ..` the secret, and `.` or `""` every version.
- 2026-10-03: Key material is wiped on every exit: `Entry()` returns
the exit code after its deferred `memguard.Purge()` has run, and only
`main` calls `os.Exit`. SIGINT and SIGTERM go through memguard's
handler, which wipes every buffer before exiting; when the process is
in the terminal's foreground process group it first restores the
terminal settings from startup, so an interrupted passphrase prompt no
longer leaves echo off.
- 2026-10-03: Every command that builds a path from a secret name
checks the name first with `vault.ValidateSecretName` and touches
nothing when it is invalid: `rm`, `mv` (both names, within a vault
and between vaults, before switching the current vault), `import`,
`version list`/`promote`/`rm`, `encrypt` and `decrypt`. The error
and `README.md` state the naming rule. Before, `secret rm ..`
deleted the whole vault and `secret rm .` every secret in it.
- 2026-10-03: The keychain unlocker's age key passphrase stays in
locked memory: it is generated into a locked buffer, and the
keychain JSON is written and read by `KeychainData` code in
`internal/secret/keychaindata.go` (tested on Linux) without
`encoding/json` holding it; the JSON field names are unchanged.
- 2026-10-02: A plain `docker build .` builds again: the size tests
skip a case that needs more locked memory than the process can
lock, and run every case under `script/cibuild`. The image stamps the
`VERSION` build argument, else `git describe --tags --always`, into
`Version`, and fails if `.git` is present but yields no version;
`make build` stamps `git describe` too, not a fixed `0.1.0`.
`.dockerignore` keeps `.git/config` out; `script/docker` is the
canonical copy.
- 2026-08-07: Updated golangci-lint to v2.12.2 with the canonical
`.golangci.yml` (all linters enabled minus the standard disable
list, `lll` 88, tests linted); bumped the `Dockerfile` lint-stage
image to the tagged v2.12.2 Debian digest; fixed all ~1550 new
findings across `internal/` and `pkg/` (line wrapping, `wsl_v5`
blank lines, sentinel errors for `err113`, `t.Parallel()` where
safe, `_test` package conversions, complexity/`dupl` helper
extraction) on branch `golangci-v2.12.2`. Reworked after review:
the `err113` sentinels in `internal/vault`, `internal/secret`,
`internal/cli` and `pkg/bip85` were reshaped so every composed
error message is byte-identical to `main`, and
`findUnlockerIDByMetadata` now returns an error so `unlocker list`
skips an unreadable `unlockers.d` entry with a warning instead of
emitting a fabricated fallback ID.
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
Makefile shims, README Entrypoints section
- 2026-03-11: Secure Enclave unlocker for hardware-backed secret
protection, plus review fixes (stub panics, derivation index, tests,
README) on branch secure-enclave-unlocker.
- 2026-02-28: Repo cleanup, removed stale .cursorrules and coverage.out.
- Audit fix wave (issues #1, #2, #3, #13, #14): skip unlockers with
missing metadata, allow uppercase secret names, fix hardcoded
derivation index, validate names in GetSecretVersion against path
traversal, return errors instead of panicking, add Warn() on silent
anomalies.
- Memory security hardening: LockedBuffer used through encrypt/decrypt
paths (Save/EncryptWithPassphrase/GetValue/gpg helpers), deprecated
bare-[]byte APIs removed.
- Per-secret keypair architecture, vault package refactor, versioning
with --version, comprehensive test suite with in-memory filesystem.
- Debug logging system (slog, GODEBUG flag, TTY-aware output).
- Renamed SEP unlocker to Keychain, reorganized import commands.
- 2025-05-28: Initial implementation (vault, age encryption, mnemonic,
CLI).
## CRITICAL MEMORY SECURITY ISSUES
# Future Steps
### Functions accepting bare []byte for sensitive data
- [x] **1. Secret.Save accepts unprotected data**: `internal/secret/secret.go:67` - `Save(value []byte, force bool)` - ✓ REMOVED - deprecated function deleted
- [x] **2. EncryptWithPassphrase accepts unprotected data**: `internal/secret/crypto.go:73` - `EncryptWithPassphrase(data []byte, passphrase *memguard.LockedBuffer)` - ✓ FIXED - now accepts LockedBuffer for data
- [x] **3. storeInKeychain accepts unprotected data**: `internal/secret/keychainunlocker.go:469` - `storeInKeychain(itemName string, data []byte)` - ✓ FIXED - now accepts LockedBuffer for data
- [x] **4. gpgEncryptDefault accepts unprotected data**: `internal/secret/pgpunlocker.go:351` - `gpgEncryptDefault(data []byte, keyID string)` - ✓ FIXED - now accepts LockedBuffer for data
- Compliance (after Next Step lands): keep main green under the new
.gitea workflow; run make check before every merge.
- Implement version-number shell completion for the second arg of
`secret version promote` and `secret version rm`
(`internal/cli/version.go`; was an in-code TODO removed for godox).
- Cover mnemonic-vs-xprv identity consistency in
`pkg/agehd/agehd_test.go` `TestMnemonicVsXPRVConsistency` (was an
in-code FIXME removed for godox).
- Darwin-gated files (`internal/secret/keychainunlocker.go`,
`seunlocker_darwin.go`, `internal/macse/macse_darwin.go`, related
tests) are not linted on the Linux CI runner and still contain lines
over the new 88-column limit; they will surface if lint ever runs on
macOS.
- Merge secure-enclave-unlocker to main once review is done.
- 1.0 critical security blockers (from repo TODO.md):
- Command injection: GPG key IDs passed unescaped to exec.Command
(pgpunlocker.go:323-327); data.String() passed unescaped to the
security command (keychainunlocker.go:472-476).
- Memory security: age identity .String() creates unprotected
copies (keychainunlocker.go:356, pgpunlocker.go:256,
version.go:155); age secret key held in a plain string in
cli/crypto.go:86,91,113; private keys exposed via buffer.Bytes()
to GPGEncryptFunc and EncryptWithPassphrase.
- Input validation: no maximum secret size (DoS).
- Timing attacks: bytes.Equal passphrase compare (cli/init.go:
209-216); non-constant-time public key compare (vault.go:95-100).
- High priority:
- Secure temporary file handling and cleanup.
- Initialize a default unlock key at vault creation.
- Confirmation prompts for destructive operations (keys rm, vault
deletion).
- Add secret rm and vault deletion commands.
- Medium priority:
- Standardize error messages; stop leaking internals.
- Graceful handling of corrupted or missing key files with recovery
suggestions.
- Validate GPG key existence before creating PGP unlock keys.
- Split oversized CLI functions.
- mlock/munlock for sensitive allocations.
- Cleanups: read statedir from environment or default instead of
passing it around.
- Enhancements: help examples, shell completion, colored output,
--quiet flag, name suggestions on miss, audit logging, hardware
integration tests (Keychain, GPG), naming consistency, vault
export/import, batch operations, search, secret metadata
(descriptions, tags).
### Functions returning unprotected secrets
- [x] **5. GetValue returns unprotected secret**: `internal/secret/secret.go:93` - `GetValue(unlocker Unlocker) ([]byte, error)` - ✓ FIXED - now returns LockedBuffer internally
- [x] **6. DecryptWithIdentity returns unprotected data**: `internal/secret/crypto.go:57` - `DecryptWithIdentity(data []byte, identity age.Identity) ([]byte, error)` - ✓ FIXED - now returns LockedBuffer
- [x] **7. DecryptWithPassphrase returns unprotected data**: `internal/secret/crypto.go:94` - `DecryptWithPassphrase(encryptedData []byte, passphrase *memguard.LockedBuffer) ([]byte, error)` - ✓ FIXED - now returns LockedBuffer
- [x] **8. gpgDecryptDefault returns unprotected data**: `internal/secret/pgpunlocker.go:368` - `gpgDecryptDefault(encryptedData []byte) ([]byte, error)` - ✓ FIXED - now returns LockedBuffer
- [x] **9. getSecretValue returns unprotected data**: `internal/cli/crypto.go:269` - `getSecretValue()` returns bare []byte - ✓ ALREADY FIXED - returns LockedBuffer
### Intermediate string variables for passphrases
- [x] **10. Passphrase extracted to string**: `internal/secret/crypto.go:79,100` - `passphraseStr := passphrase.String()` - ✓ UNAVOIDABLE - age library requires string parameter
- [ ] **11. Age secret key in plain string**: `internal/cli/crypto.go:86,91,113` - Age secret key stored in plain string variable before conversion back to secure buffer
### Unprotected buffer.Bytes() usage
- [ ] **12. GPG encrypt exposes private key**: `internal/secret/pgpunlocker.go:256` - `GPGEncryptFunc(agePrivateKeyBuffer.Bytes(), gpgKeyID)` - private key exposed to external function
- [ ] **13. Keychain encrypt exposes private key**: `internal/secret/keychainunlocker.go:371` - `EncryptWithPassphrase(agePrivKeyBuffer.Bytes(), passphraseBuffer)` - private key passed as bare bytes
## Code Cleanups
* we shouldn't be passing around a statedir, it should be read from the
environment or default.
## HIGH PRIORITY SECURITY ISSUES
- [ ] **4. Application crashes on corrupted metadata**: Code panics instead
of returning errors when metadata is corrupt, causing denial of service.
Found in pgpunlocker.go:116 and keychainunlocker.go:141.
- [ ] **5. Insufficient input validation**: Secret names allow potentially
dangerous patterns including dots that could enable path traversal attacks
(vault/secrets.go:70-93).
- [ ] **6. Race conditions in file operations**: Multiple concurrent
operations could corrupt the vault state due to lack of file locking
mechanisms.
- [ ] **7. Insecure temporary file handling**: Temporary files containing
sensitive data may not be properly cleaned up or secured.
## HIGH PRIORITY FUNCTIONALITY ISSUES
- [ ] **8. Inappropriate Cobra usage printing**: Commands currently print
usage information for all errors, including internal program failures.
Usage should only be printed when the user provides incorrect arguments or
invalid commands.
- [ ] **9. Missing current unlock key initialization**: When creating
vaults, no default unlock key is selected, which can cause operations to
fail.
- [ ] **10. Add confirmation prompts for destructive operations**:
Operations like `keys rm` and vault deletion should require confirmation.
- [ ] **11. No secret deletion command**: Missing `secret rm <secret-name>`
functionality.
- [ ] **12. Missing vault deletion command**: No way to delete vaults that
are no longer needed.
## MEDIUM PRIORITY ISSUES
- [ ] **13. Inconsistent error messages**: Error messages need
standardization and should be user-friendly. Many errors currently expose
internal implementation details.
- [ ] **14. No graceful handling of corrupted state**: If key files are
corrupted or missing, the tool should provide clear error messages and
recovery suggestions.
- [ ] **15. No validation of GPG key existence**: Should verify the
specified GPG key exists before creating PGP unlock keys.
- [ ] **16. Better separation of concerns**: Some functions in CLI do too
much and should be split.
- [ ] **17. Environment variable security**: Sensitive data read from
environment variables (SB_UNLOCK_PASSPHRASE, SB_SECRET_MNEMONIC) without
proper clearing. Document security implications.
- [ ] **18. No secure memory allocation**: No use of mlock/munlock to
prevent sensitive data from being swapped to disk.
## LOWER PRIORITY ENHANCEMENTS
- [ ] **19. Add `--help` examples**: Command help should include practical examples for each operation.
- [ ] **20. Add shell completion**: Bash/Zsh completion for commands and secret names.
- [ ] **21. Colored output**: Use colors to improve readability of lists and error messages.
- [ ] **22. Add `--quiet` flag**: Option to suppress non-essential output.
- [ ] **23. Smart secret name suggestions**: When a secret name is not found, suggest similar names.
- [ ] **24. Audit logging**: Log all secret access and modifications for security auditing.
- [ ] **25. Integration tests for hardware features**: Automated testing of Keychain and GPG functionality.
- [ ] **26. Consistent naming conventions**: Some variables and functions use inconsistent naming patterns.
- [ ] **27. Export/import functionality**: Add ability to export/import entire vaults, not just individual secrets.
- [ ] **28. Batch operations**: Add commands to process multiple secrets at once.
- [ ] **29. Search functionality**: Add ability to search secret names and potentially contents.
- [ ] **30. Secret metadata**: Add support for descriptions, tags, or other metadata with secrets.
## COMPLETED ITEMS ✓
- [x] **Missing secret history/versioning**: ✓ Implemented - versioning system exists with --version flag support
- [x] **XDG compliance on Linux**: ✓ Implemented - uses os.UserConfigDir() which respects XDG_CONFIG_HOME
- [x] **Consistent interface implementation**: ✓ Implemented - Unlocker interface is well-defined and consistently implemented
