  • Compatible with pass's password store.
  • Clears the clipboard after a timeout.
  • Configurable password generation using /dev/urandom.
  • Guards against set -x, ps and /proc leakage.
  • Easily extendible through the shell.

FAQ

How does this differ from pass or etc?

I was looking for a CLI password manager (written in shell) and wasn't happy with the options I had found. They either had multiple instances of eval (on user inputted data), lots of unsafe shell (nowhere near being shellcheck compliant.) or they were overly complex. The opposites for what I'd want in a password manager.

I decided to write my own. pash is written in POSIX sh and the codebase is minimal (120~ LOC minus blank lines and comments).

Where are passwords stored?

The passwords are stored in GPG encrypted files located at ${XDG_DATA_HOME:=$HOME/.local/share}/pash}.

How can I use a public key?

Set the environment variable PASH_KEYID to the ID of the key you'd like to encrypt and decrypt passwords with.

Example:

# Default: 'unset'.
export PASH_KEYID=XXXXXXXX

# This can also be an email.
export PASH_KEYID=dylan.araps@gmail.com

# This can also be used as a one-off.
PASH_KEYID=XXXXXXXX pash add github

How do I change the password length?

Set the environment variable PASH_LENGTH to a valid integer.

Example:

# Default: '50'.
export PASH_LENGTH=50

# This can also be used as a one-off.
PASH_LENGTH=10 pash add github

How do I change the password generation pattern?

Set the environment variable PASH_PATTERN to a valid tr string.

# Default: '_A-Z-a-z-0-9'.
export PASH_PATTERN=_A-Z-a-z-0-9

# This can also be used as a one-off.
PASH_PATTERN=_A-Z-a-z-0-9 pash add hackernews

How do I change the password store location?

Set the environment variable PASH_DIR to a directory.

# Default: '~/.local/share/pash'.
export PASH_DIR=~/.local/share/pash

# This can also be used as a one-off.
PASH_DIR=/mnt/drive/pash pash list

How do I change the clipboard tool?

Set the environment variable PASH_CLIP to a command.

NOTE: I advise that you disable clipboard history in managers like KDE's klipper before copying passwords through pash. Your Desktop Environment's clipboard manager may read entries from the X clipboard when xclip is used.

NOTE: pash will correctly clear all clipboards which have history disabled.

# Default: 'xclip -sel c'.
export PASH_CLIP='xclip -sel c'

# This can also be used as a one-off.
PASH_CLIP='xclip -sel c' pash copy github

How do I change the clipboard timeout?

Set the environment variable PASH_TIMEOUT to a valid sleep interval or off to disable the feature.

# Default: '15'
export PASH_TIMEOUT=15

# Disable timeout.
export PASH_TIMEOUT=off

# This can also be used as a one-off.
PASH_TIMEOUT=5 pash copy github

How do I rename an entry?

It's a file! Standard UNIX utilities can be used here.

How can I migrate from pass to pash?

I cannot guarantee 100% compatibility with the stores from pass as pash wasn't written as a 1:1 replacement, however users have reported that pash does in fact work fine with pass' store.

Add the following to your .shellrc or .profile.

read -r PASH_KEYID < "$PASH_DIR/.gpg-id"

export PASH_DIR=${PASSWORD_STORE_DIR:-$HOME/.password-store}
export PASH_KEYID

How can I extend pash?

A shell function can be used to add new commands and functionality to pash. The following example adds pash git to execute git commands on the password store.

pash() {
    case $1 in
        g*)
            cd "${PASH_DIR:=${XDG_DATA_HOME:=$HOME/.local/share}/pash}"
            shift
            git "$@"
        ;;

        *)
            command pash "$@"
        ;;
    esac
}
You can’t perform that action at this time.
