prs

A secure, fast & convenient password manager CLI using GPG and git to sync.

prs is a secure, fast and convenient password manager for the terminal. It features GPG to securely store your secrets and integrates git for automatic synchronization between multiple machines. It also features a built-in password generator, recipient management, history tracking, rollbacks, housekeeping utilities and more.

prs usage demo

prs is heavily inspired by pass and uses the same file structure with some additions. prs therefore works alongside with pass and all other compatible clients, extensions and migration scripts.

Features

  • Fully featured fast & friendly command line tool
  • Temporary copy secrets to clipboard
  • Uses the battle-tested GPG to secure your secrets
  • Automatic synchronization with git including history tracking
  • Supports multiple machines with easy recipient management
  • Easily edit secrets using your default editor
  • Supports smart aliases, property selection
  • Compatible with pass
  • Scriptable with -y, -f, -I flags
  • Accurate & useful error reporting

prs includes some awesome tweaks and optimizations:

  • Greatly improved synchronisation speed through git with connection reuse
  • Super fast interactive secret/recipient selection through skim
  • Prevents messing with your clipboard with unexpected overwrites
  • Commands have short and conventional aliases for faster and more convenient usage
  • Uses security best practices (secrets: zeroed, mlock, madvice, no format, etc)

Usage

# Show useful commands (based on current password store state)
prs

# Easily add, modify and remove secrets with your default editor:
prs add site/gitlab.com
prs edit site/gitlab.com
prs duplicate my/secret extra/secret
prs alias my/secret extra/alias
prs move my/secret extra/secret
prs remove site/gitlab.com

# Or generate a new secure password
prs generate site/gitlab.com

# Temporary show or copy secrets to clipboard:
prs show
prs show site/gitlab.com
prs copy
prs copy site/gitlab.com

# Manually synchronize password store with remote repository or do some housekeeping
prs sync
prs housekeeping
prs housekeeping run
prs housekeeping recrypt

# Manage recipients when using multiple machines
prs recipients add
prs recipients list
prs recipients remove
prs recipients generate
prs recipients export

# Commands support shorter/conventional commands and aliases
prs a secret  # add
prs c         # copy
prs s         # show
prs rm        # remove
prs yeet      # remove

# List all commands and help
prs help

Requirements

  • Linux, macOS, FreeBSD, Android (other BSDs might work)
  • A terminal 😎
  • gpg, gpgme and git
    • Ubuntu, Debian and derivatives: apt install git gpg libgpgme11
    • CentOS/Red Hat/openSUSE/Fedora: yum install git gnupg gpgme
    • Arch: pacman -S git gnupg gpgme
    • Alpine: apk add git gnupg gpgme
    • macOS: brew install gpg gpgme (+ gtk+3)

Install

Because prs is still in early stages, only limited installation options are available right now. Feel free to contribute.

Make sure you meet and install the requirements.

Find the latest binaries on the latest release page:

Note: for Linux the GNU (not musl) binary is recommended if it works, because it has better clipboard/notification support.

Security

Security is backed by gpg which is used all over the world and has been battle-tested for more than 20 years.

In summary, prs is secure to keep your deepest secrets when assuming the following:

  • You keep the password store directory (~/.password-store) safe
  • When using sync with git: you keep your remote repository safe
  • You use secure GPG keys
  • Your machines are secure

The content of secrets is encrypted and secured. Secrets are stored as encrypted GPG files. Some metadata is visible without decryption however. The name of a secret (file name), modification time (file modification time) and encrypted size (file size) are visible when you have access to the password store directory.

Security best practices are used in prs to prevent accidentally leaking any secret data. Sensitive data such as plaintext, ciphertext and others are referred to as 'secret' here.

Secrets are/use:

  • Zeroed on drop
  • Locked to physical memory, cannot leak to swap/disk (mlock)
  • Locked into memory, cannot be dumped/not included in core (madvice)
  • Not written to disk to edit (if possible)
  • String formatting is blocked
  • Constant time comparison to prevent time based attacks
  • Minimally cloned

The protection against leaking secrets has its boundaries, notably:

  • prs show prints secret data to stdout
  • prs edit may store secrets in a secure temporary file on disk if secure locations such as (/dev/shm) are not available, it then opens it in your default editor, and removes it afterwards
  • prs copy copies secret data to your clipboard, and clears it after 20 seconds

Note: prs does not provide any warranty in any way, shape or form for damage due to leaked secrets or other issues.

FAQ

Is prs secure? How secure is prs?

Please read the Security section.

How do I use sync with git?

If you already have a remote password store repository that is compatible with prs, clone it using:

# Clone existing remote password store, automatically enables sync
prs clone MY_GIT_URL

# List secrets
prs list

If you do not have a remote password store repository yet, create one (an empty private repository on GitHub or GitLab for example), and run the following:

# Initialize new password store (if you haven't done so yet)
prs init

# Initialize sync functionality (if you haven't done so yet)
prs sync init

# Set your remote repository URL and sync to push your password store
prs sync remote MY_GIT_URL
prs sync

When sync is enabled on your password store, all commands that modify your secrets will automatically keep your remote store in sync.

To manually trigger a sync because you edited a secret on a different machine, run:

prs sync

How do I use prs on multiple machines and sync between them?

Note: adding and using your existing password store on a new/additional machine requires you to have access to a machine that already uses the store during setup.

First, you must have a password store on one machine. Create one (with prs init) if you don't have any yet. You must set up sync with a remote git repository for this passwords store, see the How do I use sync with git section.

To use your existing password store on a new machine, install prs and clone your remote password store:

# On new machine: clone existing password store from git remote
prs clone MY_GIT_URL

Then add a recipient to the password store for your new machine. I highly recommend to use a new recipient (GPG key pair) for each machine (so you won't have to share secret GPG keys). Add an existing secret GPG key as recipient, or generate a new GPG key pair, using:

# On new machine: add existing recipient or generate new one
prs recipients add --secret
# or
prs recipients generate

Your new machine can't read any password store secrets yet, because they are not encrypted for its recipient yet. Go back to an existing machine you already use the store on, and re-encrypt all secrets to also encrypt them for the new recipient:

# On existing machine: re-encrypt all secrets
prs housekeeping recrypt --all

This may take a while. Once done, sync on your new machine to pull in the updated secrets:

# On new machine: pull in all re-crypted secrets
prs sync

# You're done!
prs list

How do I use prs on mobile?

prs itself does not support mobile, but there are compatible clients you can use to use your password store on mobile.

See Compatible Clients on passs website.

Can I recover my secrets if I lost my key?

No, if you lose all keys, there is no way to recover your secrets.

You might lose your key (recipient, GPG secret key) if your machine crashes or if you reinstall it's operating system.

If you are using the same password store on multiple machines with git sync, you can still read the secrets on your other machines. To re-add the machine you lost your key on, remove the password store from it and see this section.

Is prs compatible with pass?

Yes.

prs uses the same file structure as pass. Other pass clients should be able to view and edit your secrets.

prs does add additional files and settings, some prs features might not work with other pass clients.

See a list of compatible pass clients here.
