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, Tomb support and more.

mv ./prs /usr/local/bin/prs

./prs --help

Build

To build and install prs yourself, you need the following:

• Rust 1.64 or newer (MSRV)
• The 'Build' requirements.

Not all features are supported on macOS or Windows. The default configuration should work. When changing compile time features, make sure to check for compatibility. See compiler features.

Compile and install

To compile and install prs with the default features follow these steps:

• Compile and install it directly from cargo:

  # Compile and install from cargo
  cargo install prs-cli -f
  
  # Start using prs
  prs --help

• Or clone the repository and install it with cargo:

  # Clone the project
  git clone https://github.com/timvisee/prs.git
  cd prs
  
  # Compile and install
  cargo install --path cli -f
  
  # Start using prs
  prs --help
  
  # or run it directly from cargo
  cargo run --release --package prs-cli -- --help
  
  # or invoke release binary directly
  ./target/release/prs --help

Compile features / use flags

Different use flags are available for prs to toggle whether to include various features and cryptography backends. The following features are available, some of which are enabled by default:

To enable features during building or installation, specify them with --features <features...> when using cargo. You may want to disable default features first using --no-default-features. Here are some examples:

# Default set of features with backend-gnupg-bin, install or build, one of
cargo install --path cli --features backend-gnupg-bin
cargo build --path cli --release --features backend-gnupg-bin

# No default features, except required, one of
cargo install --path cli --no-default-features --features backend-gpgme
cargo install --path cli --no-default-features --features backend-gnupg-bin

# With alias, clipboard and notification support, one of
cargo install --path cli --no-default-features --features backend-gpgme,alias,clipboard,notify
cargo install --path cli --no-default-features --features backend-gnupg-bin,alias,clipboard,notify

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. To protect against this metadata leakage you may use a Tomb.

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 its 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.

What is Tomb?

Tomb is a file encryption system. It can be used with prs to protect against metadata leakage of your password store.

When using Tomb with prs, your password store is stored inside an encrypted file. prs automatically opens and closes your password store Tomb for you as needed. This makes it significantly harder for malicious programs to list your password store contents.

This feature is inspired by pass-tomb, which is a pass extension for Tomb support. In prs this functionality is built-in.

Note: Tomb is only supported on Linux.

How to use Tomb?

prs has built-in support for Tomb on Linux systems. Please make sure prs is compiled with the tomb feature, and that Tomb is installed.

To initialize a Tomb for your current password store, simply invoke:

# Initialize tomb, this may take some time
prs tomb init

# Read tomb status
prs tomb status

To initialize a new password store in a Tomb, first initialize the password store then initialize the Tomb:

# Initialize new password store
prs init

# ...

# Initialize tomb, this may take some time
prs tomb init

If you already have a Tomb created with pass-tomb, no action is required. prs has seamless support for it, and it should automatically manage it for you. Invoke prs tomb status to confirm it is detected.

How to use Tomb on multiple machines?

A Tomb is local on your machine and is not synced. To use a Tomb on multiple machines you must initialize it on each of them.

Simply run prs tomb init on machines you don't use a Tomb on yet, and after cloning your password store on a new machine.

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 may not work with other pass clients.

While the backing file structure is compatible, the command-line interface is not and differs from pass. This is to remove ambiguity and to improve overall usability.

See a list of compatible pass clients here.
