Install scrt4

One command. macOS, Linux, and WSL. Hardware-bound by FIDO2.

Install with a single command — same on every OS

# Requires curl, bash, and a FIDO2 authenticator (YubiKey, Touch ID, Windows Hello, or phone passkey).
curl -fsSL https://install.llmsecrets.com/native | sh
# After install, enroll your authenticator and open a session:
scrt4 setup && scrt4 unlock
AGPL-3.0 · source-available · SHA256-verified · no license key · no telemetry

Quick start

1

Register your hardware authenticator (one-time).

scrt4 setup
2

Unlock a session (default 20 hours).

scrt4 unlock
3

Move a secret out of your .env and into the vault.

scrt4 add API_KEY=sk-live-...
4

Run commands with placeholder injection — the AI never sees the values.

scrt4 run 'curl -H "Authorization: Bearer $env[API_KEY]" https://api.example.com'

Uninstall

One-shot uninstaller. Removes the daemon, CLI, and session data. Your vault stays on disk until you delete it.

Verify the installer script (before piping to sh)

Download the installer, hash it, and compare against the digest published beside it. If they match, the bytes you are about to run are the bytes we published.

# Published SHA256 for scrt4-native.sh
13aed19159e4cc87f581aa594bf7766caf777c9b9a03c0ef91a4de12ce795656 scrt4-native.sh
# The published digest for the installer:
curl -fsSL https://install.llmsecrets.com/native.sha256
# Verify locally, then run:
curl -fsSL https://install.llmsecrets.com/native -o scrt4-native.sh && sha256sum scrt4-native.sh && sh scrt4-native.sh

Verify your install (SHA256)

The installer verifies these checksums automatically. You can also verify by hand — the current release tag is v0.4.6, and the live manifest lives at SHA256SUMS.
