vault unlock --idle counts the duration from the last command that used the key rather than from the unlock: the agent resets its timer each time it hands the key out. The agent loop no longer needs its own goroutine. packaging/repo.sh builds the dixon-vault .deb, .rpm and Arch packages from a release tag (a clean git archive) with nfpm for amd64, arm64, armv7, 386 and riscv64, then publishes them to the apt, dnf and pacman repositories at repo.dixon.cx: apt-ftparchive with a signed InRelease, createrepo_c (in a Fedora container) with signed RPMs and repomd.xml, and repo-add (in an Arch container) with signed packages and database. Indexes cover every package in the repository, under a lock, so other projects publishing with their copy of the script are kept. The package is dixon-vault because vault is HashiCorp Vault in Arch's [extra] and HashiCorp's own repositories; it conflicts with vault. README, guide and CLAUDE.md point at the repository.

.TH VAULT-UNLOCK 1 "October 2026" "vault" "User Commands"

.SH NAME
|
|
vault-unlock, vault-lock \- remember the unlocked key for a while, or forget it
|
|
.SH SYNOPSIS
|
|
.B vault unlock
|
|
.RB [ \-\-for
|
|
.IR DURATION ]
|
|
.RB [ \-\-idle ]
|
|

.RB [ \-\-key
|
|
.IR PATH ]
|
|
.SH DESCRIPTION
|
|
.B unlock
|
|
asks for the passphrase, checks it, and starts a helper process, much like
|
|
.BR ssh\-agent (1),
|
|
that holds the unlocked key in memory until \fIDURATION\fR has passed
|
|
(default 5m). Until then every command using the same key file skips the
|
|
passphrase prompt. By default the deadline is fixed when you unlock and
|
|
using the key does not extend it; with \fB\-\-idle\fR it is \fIDURATION\fR
|
|
after the last command that used the key. Running
|
|
.B unlock
|
|
again replaces the helper with a fresh one.
|
|
.PP
|
|
.B lock
|
|
tells the helper to wipe the key and exit at once.
|
|
.PP
|
|
The key reaches the helper over a pipe and is never written to disk. Its
|
|
memory is locked against swapping and excluded from core dumps; on Linux the
|
|
helper is also not debuggable. It answers only on a Unix socket inside
|
|
\fI$XDG_RUNTIME_DIR/vault-UID\fR (or the temporary directory), a directory
|
|
that must belong to this user with mode 0700. Rebooting ends it too.
|
|
.PP
|
|
While the key is unlocked, any program running as this user can use it, and
|
|
it is whichever key the passphrase opened, real or decoy. Lock before
|
|
handing the machine to anyone.
|
|
.SH OPTIONS
|
|
.TP
|
|
.BI \-\-for " DURATION"
|
|
How long to remember the key, such as 90s, 5m or 2h. Default 5m.
|
|
.TP
|
|
.B \-\-idle
|
|
Count \fIDURATION\fR from the last time a command used the key, rather than
|
|
from the unlock, so the key stays while you keep working.
|
|
.PP
|
|
See also \fB\-\-key\fR in
|
|
.BR vault (1).
|
|
.SH ENVIRONMENT
|
|
.TP
|
|
.B VAULT_PASSPHRASE
|
|

|
|
.BR unlock .
|
|
When set for any other command, it is used instead of the remembered key.
|
|
.TP
|
|
.B XDG_RUNTIME_DIR
|
|
Where the helper's socket directory goes.
