check / check (push) Failing after 1s
Check errors by identity, not by message text, in tests (closes #49)
Tests that asserted a failure by a fragment of its message now use
errors.Is: a refactor returning the wrong error, or wrapping with %v
instead of %w, now fails them. New tests return each exported error of
internal/vault and pkg/bip85 that no test returned, and check wrapped
causes (os.ErrNotExist, ErrMnemonicMismatch through GetSecret,
ErrInvalidPathComponent through DeriveBIP85Entropy). The 999-versions
test moves into package secret to name its unexported error. Checks of
errors no test can name keep their text; they are listed on the issue.

Completed Steps

  • 2026-10-04: Tests check which error a failure returns with errors.Is, not by matching words of its message (#49). Every exported error that can be returned has a test that the function returns it, and errors wrapping a cause are checked through the wrapping. Checks that still match text, because the error has no exported value the test can name, are listed on the issue.
  • 2026-10-04: When a vault cannot be opened through its current unlocker, because a file the unlocker needs is missing or damaged, its keychain item or Secure Enclave key is gone, or the passphrase is wrong, the error now ends by naming the vault, saying that it still opens with its mnemonic, and that secret unlocker add passphrase, run with SB_SECRET_MNEMONIC set to it, gives the vault a new unlocker; for a vault that is not the current one, as in secret move between vaults, it says to run secret vault select first (#47). Before, it ended with the bare cause. The advice is given only when the vault metadata records the key the mnemonic derives, so not for a vault created without a mnemonic, and not when the passphrase could not be read at all. secret vault import is not named: it refuses a vault that has a long-term key. secret encrypt and secret decrypt now read the key secret through vault.GetSecret, as secret get does, so they give the same advice; Secret.GetValue, the other way to get the long-term key, is removed. When a secret's current file cannot be read, the error says that secret version list lists its versions and secret version promote makes one current. The causes stay wrapped.
  • 2026-10-04: An unlocker's ID is the name of its directory in unlockers.d, so no two unlockers of a vault share one (#98). Before, a keychain or Secure Enclave unlocker's ID was its creation time to the minute and the host name, and a passphrase unlocker's the time to the minute, so two created within a minute shared an ID, and unlocker select, unlocker remove and the selection unlocker add makes acted on the older one. A PGP unlocker's ID was pgp- and its key's fingerprint; a second PGP unlocker for a key is still refused, now by comparing the fingerprint in the other unlockers' metadata. unlocker list and the shell completion of unlocker select and unlocker remove take each ID from the directory the unlocker was read from, no longer by matching metadata, so two unlockers with the same metadata are listed apart; an unlocker of an unknown type is listed under its directory name, and completion now offers Secure Enclave unlockers too. The keychain and Secure Enclave code was type-checked by script/lint-darwin, never run; a test on Linux lists, completes, selects and removes each of two passphrase unlockers with the same metadata by its own ID.
  • 2026-10-04: README's Storage Architecture, secret version promote, Technical Details and Testing text matches the code (#102). current and currentvault are plain files holding a name, not symbolic links; a version's metadata is the encrypted metadata.age; the state directory is berlin.sneak.pkg.secret in the user's configuration directory, not ~/.local/share/secret, and holds the lock file. Also corrected: the code sets up no Touch ID for the keychain or Secure Enclave unlocker, and the Secure Enclave only decrypts; per-version keys give no forward secrecy; pub.age is not age-encrypted; vault metadata holds no vault name. Testing lists only make test.
  • 2026-10-04: secret init and secret vault create create a vault whole or not at all (#105). vault.CreateVault now takes the unlocker passphrase too, writes the vault directory with its metadata, long-term public key and passphrase unlocker, longterm.age included, into a temporary directory, renames that into vaults.d once it is complete, and only then makes the vault current. Before, either command killed after the passphrase prompt but before the unlocker was written left a vault with no unlocker, which vault create had already made current and which neither command would create again. Killed part-way now, it leaves no vault, and the next command that takes the lock deletes the temporary directory; or, killed between the rename and making the vault current, a complete vault that is not current, which secret vault select makes current.
  • 2026-10-04: A failed secret unlocker add keychain or secret unlocker add secure-enclave no longer leaves its keychain item or Secure Enclave key behind (#89). CreateSecureEnclaveUnlocker gets the long-term key before it creates the Secure Enclave key, so that a wrong passphrase creates none, and deletes the key again if encrypting with it or writing the unlocker then fails. macse.CreateKey finds the new key's hash right after sc_auth creates it, and fails with an error naming the key's label if it cannot; it deletes the key again if getting its public key then fails. The Objective-C was only read, never compiled or run, and so was macse_darwin.go, which is cgo only. CreateKeychainUnlocker writes all of the unlocker's files, the metadata among them, before it stores the item in the keychain, and deletes the item again if moving the unlocker into place then fails. A failure to delete is reported along with the first error. The tests of this run only on macOS: the Secure Enclave one in a build with cgo on a Mac with a Secure Enclave, the keychain one in a build with cgo.
  • 2026-10-04: What a command killed part-way left under a .tmp- name (#75), the temporary directories of secret.TempDirFor and the temporary files of secret.WriteFileAtomic, encrypted keys included, is deleted by the next command that takes the state directory lock. Before, it stayed until deleted by hand. A command writes finished into the lock file just before it releases the lock; the next one to take the lock searches only when it does not find that, so after a command that finished nothing is searched, however many secrets and versions there are. The search looks in the state directory, each vault, each secret and each version, the only directories those helpers make them in. A command that only reads takes no lock and deletes nothing. A failure to delete is warned about and the command goes on. An unlocker directory with no metadata file was already removed by secret unlocker remove given its directory name; a test now shows it.
  • 2026-10-04: An age identity's private key goes into a locked buffer through secret.IdentityToLockedBuffer everywhere (#38): the vault's long-term key when a passphrase, PGP, keychain or Secure Enclave unlocker is created, the new unlocker's own key, a new secret version's key, and the key secret encrypt generates. Before, each place converted the string age returns to bytes and left the string in ordinary memory. The function moves the string's own bytes into the buffer, which overwrites them; the copies age makes while writing the string remain, as its comment says. The 1.0 memory-security entry below no longer lists these places, internal/cli/crypto.go among them, nor version.go:155, which was internal/secret/version.go, not internal/cli/version.go.
  • 2026-10-04: script/lint-darwin (make lint-darwin) runs go vet and golangci-lint in docker on the code as a macOS build compiles it (GOOS=darwin), with cgo off (#50). script/check runs it, and the Dockerfile lint stage runs its commands, so script/cibuild does too. Before, CI on Linux never compiled the files built only for macOS. Compiling cgo code for macOS needs Apple's SDK headers, and both internal/macse and github.com/keybase/go-keychain are cgo on macOS. So the three functions that call go-keychain moved from keychainunlocker.go to keychainunlocker_cgo.go, built only with cgo on macOS like macse_darwin.go. A macOS build without cgo, which before did not compile, gets keychainunlocker_nocgo.go and the macse stub instead, whose errors say the keychain or Secure Enclave needs a macOS build with cgo. The check covers the rest of the keychain unlocker, the Secure Enclave unlocker and the macOS-only tests other than keychainunlocker_test.go, whose lint findings are fixed. For the length and complexity limits, parts of GetIdentity, getLongTermPrivateKey and CreateKeychainUnlocker moved into functions of their own, and the Secure Enclave unlocker derives the long-term key from the mnemonic through the same function as the keychain unlocker instead of a copy of it. Lines over 88 columns in the files the check cannot see are wrapped.
  • 2026-10-04: secret rm, secret version rm, secret vault remove and secret unlocker remove ask [y/N] before removing anything (#39), naming what they remove: the secret, its vault and its version count; the version, secret and vault; the vault and its secret count; the unlocker, its vault and whether it is the last, and for the last the vault's secret count and that the vault then opens only with its mnemonic. Only y or yes goes ahead. Without --force, a command whose stdin is not a terminal fails at once. --force (now also on rm and version rm) removes without asking; it replaces the old refusals to remove a vault with secrets or the last unlocker of one without --force, which the question now covers. The checks run, and the question is asked, before the state directory lock is taken; under the lock the checks run again, and if they would ask a different question, nothing is removed. secret rm fails when it cannot count the versions.
  • 2026-10-04: A crash while an unlocker is being replaced no longer leaves a current unlocker that cannot open the vault (#71). Every new unlocker gets a directory of its own, named with the time to the nanosecond: passphrase-<time>, <host>-pgp-<time>, and for a keychain or Secure Enclave unlocker the keychain item or Secure Enclave key, which names the directory, carries the time instead of the day. secret.WriteDir fails on a directory that exists instead of writing into it. unlocker add passphrase writes the new unlocker, makes it current, and only then removes the vault's other passphrase unlockers; a crash between the last two steps leaves the old one beside the new, and the old passphrase still opens the vault through it until the next unlocker add passphrase or an unlocker remove removes it. A PGP, keychain or Secure Enclave unlocker added on the same host and day as another of its type is added beside it instead of replacing it.
  • 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 (#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: .golangci.yml is again the canonical file from sneak/prompts, byte for byte (#66). It runs gomodguard_v2 in place of the deprecated gomodguard, so the lint no longer warns, and enables depguard with a rule that keeps net/http/httptest out of non-test files. Neither raised a finding in this repo.
  • 2026-10-04: secret unlocker add pgp works on Linux (#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 .. (#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 (#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 (#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.
  • 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 (#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 (#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 (#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 (#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.
  • 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.
  • 2026-08-07: Added .editorconfig (#27).
  • 2026-07-07 Adopted scripts-to-rule-them-all: script/ entrypoints, Makefile shims, README Entrypoints section
  • 2026-07-07: Added REPO_POLICIES.md and the make hooks target; .gitea/workflows/check.yml now runs script/cibuild.
  • 2026-03-30: Added the make fmt-check target and .gitea/workflows/check.yml, which runs docker build on every push; the Dockerfile base images are pinned by sha256.
  • 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).

Future Steps

  • 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).
  • CI does not compile, lint or test the files built only with cgo on macOS, since compiling them needs Apple's SDK: internal/secret/keychainunlocker_cgo.go (the three functions that call go-keychain) with keychainunlocker_test.go, and internal/macse (macse_darwin.go, macse_test.go, the Objective-C sources). Lint has never run on them, so it would likely find more there than the line lengths. No macOS test runs in CI. A macOS runner would cover all of it (asked on #50).
  • 1.0 critical security blockers (from repo TODO.md):
    • Memory security: age writes an identity's private key out as a string in ordinary memory, and the copies it makes on the way stay there (secret.IdentityToLockedBuffer overwrites only the string itself).
  • Medium priority:
    • Standardize error messages; stop leaking internals.
    • Split oversized CLI functions.
  • Cleanups: read statedir from environment or default instead of passing it around.
  • Enhancements: help examples, 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).
