🔐 sekrt

sekrt — secret, with the vowels taken out. Everything else is AES-256, and only you can read it.

A fast TUI + CLI secret manager for developers and DevOps engineers. Like pass, but with a modern Textual interface, first-class API key, SSH keypair and .env file support, and painless sync through any private git remote (GitHub, GitLab, self-hosted — anything).

• 🔑 Passwords & API keys — organised in folders, generated, copied with auto-clearing clipboard
• 📄 .env files — encrypt the .env of any repo into your vault, restore it in any fresh clone with one command
• 🗝️ SSH keypairs — import, generate (ed25519), and restore with correct permissions
• ☁️ Git sync — every change is a commit; sekrt sync pushes/pulls a private repo
• 🖥️ TUI + CLI — a full keyboard-driven interface and script-friendly commands
• 🪶 Lightweight — three dependencies (textual, click, cryptography), no daemon, no sudo, no gpg setup

Install

uv tool install sekrt      # recommended
# or: pipx install sekrt
# or: pip install --user sekrt

Requires Python 3.11+. Nothing else to set up — no daemon, no GPG keyring, no sudo.

Quickstart

sekrt init                             # create a vault at ~/.local/share/sekrt
sekrt add work/github -u alberto -g    # generate & store a password
sekrt get work/github -c               # copy it (clipboard clears in 45s)
sekrt                                  # open the TUI

That's a working local vault. init prompts you to choose (and confirm) a passphrase — that passphrase is the vault; there's no recovery if you lose it, so pick something you'll remember, and see the security model below before you rely on it for real.

Anything that touches a secret's contents (get, show, edit, add, mv, env, ssh, …) decrypts the vault key on demand, so by default you'll be prompted for the passphrase each time — ls, find, rm and status don't need to decrypt anything, so they never prompt. Run sekrt unlock once and the rest stop prompting for an hour (-t MIN to change that), courtesy of a RAM-backed, user-private session cache — like gpg-agent, without the agent. sekrt lock forgets it immediately.

sekrt unlock              # cache the key for 60 min
sekrt get work/github -c  # no prompt this time
sekrt lock                # forget it now

Syncing with a git remote

The vault is a plain git repository. sekrt sync is git pull --rebase then git push against origin — so you need an empty private repo to point it at (GitHub, GitLab, Gitea, a bare repo over SSH — anything git can push to).

# 1. create an empty private repo, e.g. `gh repo create secrets --private --clone=false`
sekrt remote git@github.com:you/secrets.git   # or: sekrt init --remote <url> on a fresh vault
sekrt sync                                    # first push

On another machine, point $SEKRT_VAULT at a fresh directory (or just run sekrt init, then sekrt remote <url> — sync will pull the rest):

sekrt remote git@github.com:you/secrets.git
sekrt sync

Every add/edit/mv/rm auto-commits locally; sekrt sync is what actually talks to the remote. Want every change pushed immediately instead?

sekrt autosync on

Remember: the remote only ever sees ciphertext and entry names — see what the remote sees below.

The .env workflow

.env files never land in your project repos — so every fresh clone starts with a scavenger hunt. sekrt ends it:

cd ~/code/my-saas       # any git repo
sekrt env push         # encrypts .env into the vault, keyed by the repo's origin URL
sekrt sync

Months later, on another machine:

git clone git@github.com:you/my-saas.git && cd my-saas
sekrt env pull         # .env is back, byte for byte (0600 perms)

The key is the repo's origin URL, not the path on disk — so a clone anywhere finds its own file, and HTTPS vs SSH remotes resolve to the same key. It handles several env files per repo (sekrt env push .env apps/*/.env.*), reports what actually changed rather than rewriting blindly, and never overwrites a local file you've edited without --force.

📄 Full guide: the .env workflow — how repos are identified, monorepos with one env file per service, the overwrite rules, using --repo for forks and renames, what the remote can see, and troubleshooting.

SSH keys

sekrt ssh add laptop --key ~/.ssh/id_ed25519    # import an existing keypair
sekrt ssh add deploy --generate                 # or generate a fresh ed25519 key
sekrt ssh pub deploy                            # print the public key for GitHub
sekrt ssh restore deploy --dir ~/.ssh           # on a new machine: 0600/0644, done

The TUI

sekrt with no arguments (or sekrt tui) opens the interface: a folder tree of your vault, fuzzy filtering, a masked detail view, add/edit forms with a built-in password generator, and one-key sync.

Key	Action
/	filter entries
c	copy the entry's secret (auto-clears in 45s)
u	copy the entry's username
r	reveal / mask fields
a / e / d	add / edit / delete
s	sync with the git remote
l	lock the vault (prompts for the passphrase again)
q	quit

.env and SSH entries show up in the tree read-only — add, restore and inspect those from the CLI (sekrt env, sekrt ssh) instead.

Security model

• Encryption: every entry is an independent file encrypted with AES-256-GCM. The key is derived from your passphrase with scrypt (N=2¹⁵, r=8, p=1, random per-vault salt).
• Tamper binding: an entry's logical name is the GCM associated data — a ciphertext moved or renamed by an attacker fails to decrypt.
• What the remote sees: entry names and folder structure (like pass), timestamps, and commit history. Entry contents are always ciphertext. Use names accordingly (work/github, not password-is-hunter2).
• Session cache: sekrt unlock stores the derived key (never the passphrase) in $XDG_RUNTIME_DIR — tmpfs on Linux: RAM-backed, user-only (0600), wiped on logout — with a TTL. sekrt lock clears it immediately.
• Clipboard: auto-clears after 45 s, and only if it still holds the copied value. Secrets are never passed through argv.
• Files: vault dir 0700, entries 0600, atomic writes, restored SSH keys 0600/0644.
• Threat model: protects secrets at rest and in your git remote. It does not protect against an attacker with root/physical access to your unlocked machine — nothing userspace does.
• Your passphrase is the whole game: anyone who obtains the vault files (including whoever hosts your sync remote) can attempt an offline brute-force. scrypt makes each guess expensive, but a weak passphrase falls anyway — use a long one. sekrt enforces a minimum of 8 characters; treat that as a floor, not a target.
• A compromised remote cannot read entry contents or swap ciphertexts between names (AEAD name binding), but it can delete entries, serve you an old version of the vault (rollback), or corrupt the vault config. If sekrt sync suddenly reports missing entries or a passphrase failure, investigate before typing your passphrase anywhere else.

Vault location & configuration

What	Default	Override
Vault directory	~/.local/share/sekrt	$SEKRT_VAULT
Passphrase (CI/scripts)	interactive prompt	$SEKRT_PASSPHRASE
Editor for sekrt edit	$EDITOR	$VISUAL

The vault is a plain git repository — inspect it any time with sekrt git log.

Upgrading from tupacs? This project was published under that name through 0.1.0. The TUPACS_* variables above still work as fallbacks, and vaults written by 0.1.0 (.tup entry files) are read as-is. Only the vault directory needs a hand — see the migration note.

Why not just pass?

pass is excellent, and sekrt borrows its best idea (one encrypted file per secret, git-friendly). Differences: no GPG key management — a single passphrase with scrypt+AES-GCM; a real TUI; structured entries (username, URL, notes — not just a text blob); and purpose-built .env and SSH-key workflows.

Development

git clone https://github.com/alberto-rota/sekrt && cd sekrt
uv sync                 # installs everything incl. dev deps
uv run pytest           # tests
uv run ruff check .     # lint
uv run sekrt --help

Try changes against a throwaway vault so you never touch your real one:

export SEKRT_VAULT=/tmp/sekrt-dev SEKRT_PASSPHRASE=dev
uv run sekrt init && uv run sekrt

Contributions welcome — see CONTRIBUTING.md.

The docs/*.gif demos are recorded with VHS from the tapes in docs/vhs/. Run them from the repo root with sekrt on $PATH (brew install vhs, then uv tool install --editable .):

vhs docs/vhs/quickstart.tape   # -> docs/quickstart.gif
vhs docs/vhs/tui.tape          # -> docs/tui.gif (run quickstart.tape first to seed the demo vault)
vhs docs/vhs/env.tape          # -> docs/env.gif
vhs docs/vhs/env-multi.tape    # -> docs/env-multi.gif
vhs docs/vhs/env-safety.tape   # -> docs/env-safety.gif

The three env tapes are self-contained: each one rebuilds its fixture — real git repos with remotes, a fresh clone, and a scratch vault under /tmp/sekrt-vhs-env — by running docs/vhs/setup-env-demo.sh, and points $HOME at it, so your real vault and ~/.gitconfig are never touched.

docs/screenshot.svg (the image at the top of this file) is a Textual export rather than a recording, so it has its own generator:

uv run python docs/vhs/make-screenshot.py   # -> docs/screenshot.svg

Roadmap

• sekrt grep — search inside decrypted entries
• TOTP / 2FA codes (sekrt otp NAME)
• Import from pass, Bitwarden, 1Password CSV
• Diceware passphrase generation
• Windows clipboard & session-cache support
