Python builds its PasswordGenerator with
`policy=self.config_manager.get_password_policy()` and merges an entry's own
`policy` block over that base per derivation. The port merged the entry block
over hardcoded defaults and never read the profile config at all, so every
entry in a profile with a non-default policy derived a *different password*
than Python. Nothing failed anywhere; it reached the user as a wrong password,
which is indistinguishable from data loss at the point of use.
materializeSecret now takes a `basePolicy` and merges the entry block over it.
All three callers supply the profile config's policy:
- program.ts via basePolicyForOptions, resolved lazily so `entry list` and
friends don't pay a second BIP-39 seed derivation for a policy they never
use. `--vault` names an index file rather than a profile, so the config is
looked for beside it and falls back to defaults when absent.
- agent.ts from join(appDir, fingerprint), so a token-scoped reveal returns
what the owner sees.
- the TUI through a new sessionSecret helper that every menu path goes
through, so a future call site cannot silently omit the base.
`util generate-password` is deliberately unchanged: it has no entry and no
profile, so its flags are the whole policy. It now says so in its own help
text rather than leaving the reader to infer it.
Evidence: js/packages/cli/test/passwordPolicy.test.ts covers config-only v2,
an entry overriding exactly one field, config-only v1 and exclude_ambiguous,
against values computed by the Python implementation — each also asserted
unequal to what the pre-fix code produced, so a regression fails loudly rather
than needing someone to notice a changed constant. Mutation-verified twice:
dropping basePolicy from the merge in secrets.ts, and making
basePolicyForOptions return {}, each turn all four red.
Found by the 2026-08-18 independent audit (js/SECURITY_AUDIT.md). The parity
fixture suite could not have caught this: those fixtures call generatePassword
with one already-resolved policy, so they prove the algorithm and say nothing
about where the policy came from.

seedpass-js
The SeedPass command-line interface, TypeScript port.
It reads and writes the same ~/.seedpass profiles as the Python
implementation — same derivations, same vault format, same Nostr sync — and
adds a session agent plus a scoped-token surface designed for AI agents and
automation.
Install
Requires Node.js 22 or newer.
# from a checkout
cd js && pnpm install && pnpm --filter @seedpass/cli build
node packages/cli/dist/seedpass-js.mjs --version
The build produces one self-contained file (dist/seedpass-js.mjs) plus a
.sha256 next to it. Copy it anywhere on your PATH; it has no runtime
dependencies beyond Node itself.
Quick start
export SEEDPASS_APP_DIR=~/.seedpass # omit to use the default
# Create a profile (mnemonic and password come from the environment,
# never from the command line)
export SEEDPASS_MNEMONIC="your twelve or twenty-four words"
export SEEDPASS_PASSWORD="your master password"
seedpass-js fingerprint add --name main
unset SEEDPASS_MNEMONIC # not needed again
# Unlock once per session through the agent
seedpass-js agent start &
seedpass-js vault unlock --ttl 900
seedpass-js entry add password github.com --length 20 --username you
seedpass-js entry reveal github.com
seedpass-js entry totp-codes
seedpass-js use github.com --clipboard
seedpass-js vault lock
Design: reference-first output
Default output never contains secret values. Entries are addressed by
reference (sp://entry/<id>), and secret-bearing fields are reported as
has_* flags:
$ seedpass-js entry get api-token
{ "id": "5", "ref": "sp://entry/5", "label": "api-token",
"kind": "key_value", "has_value": true, ... }
Plaintext leaves the vault only through commands that say so
(entry reveal, entry totp-codes, entry export-document,
util generate-password), or through a sink, which delivers a secret to its
destination without routing it through this process's output:
seedpass-js use api-token --exec ./deploy.sh # SEEDPASS_SECRET in the child env
seedpass-js use api-token --stdin-to "wc -c" # quote specs that contain flags
seedpass-js use api-token --clipboard
Scoped tokens for agents
An agent can be given a token that grants exactly what it needs and nothing else. Secrets are materialized inside the session agent, so the token holder never receives the seed and can never escalate to owner operations.
# As the owner:
seedpass-js agent token-issue --scope read use \
--kind key_value --label-regex '^api-' --uses 2 --ttl 600
# In the agent's process — no mnemonic, no password:
export SEEDPASS_TOKEN=<token>
seedpass-js entry list # metadata only
seedpass-js use api-token --exec ./deploy.sh # permitted
seedpass-js entry reveal api-token # denied: scope 'reveal' not granted
# Back as the owner — every grant, delivery and denial is recorded:
seedpass-js agent audit-verify
seedpass-js agent audit-tail -n 20
Environment
| Variable | Purpose |
|---|---|
SEEDPASS_APP_DIR |
Profile directory (default ~/.seedpass) |
SEEDPASS_MNEMONIC |
Parent seed; needed for profile creation, otherwise use the agent |
SEEDPASS_PASSWORD |
Master password, for fingerprint add and vault unlock |
SEEDPASS_TOKEN |
Scoped token; puts the CLI in token mode |
SEEDPASS_AGENT_SOCK |
Override the agent socket path |
SEEDPASS_SECRET |
Set by use --exec in the child process only |
Compatibility
Interoperability with the Python implementation is verified on every change
by scripts/cross_impl_check.py: each side opens the other's profiles,
backups round-trip, edits are mutually visible, conflict merges agree, and a
snapshot published by Python restores here with secrets intact. See
docs/typescript_port_compatibility_matrix.md.
Not yet ported: PGP RSA keys (not byte-reproducible; ed25519 is at parity),
and the semantic and api command groups.
