# What is it?

• Manage cryptographic keys, sigchains and user identities.
• Search for keys, verify and import them.
• Securely store passwords and secrets.
• Encrypt, decrypt, sign, verify.
• Create a secure connection (Wormhole) between 2 computers.
• Most features available in both the app and on the command line.
• 100% open source (github.com/keys-pub) and cross platform (macOS, Windows, Linux).
• Coming soon: Backup keys/secrets to your private self-hosted storage on S3, GCP, etc.
• Coming soon: Support for hardware keys.
• Coming soon: Mobile apps.

Using the desktop app to encrypt a message from gabriel@github to multiple recipients.

# How does it work?

The default key is a Ed25519/X25519 key capable of signing and encryption.

We can link this key to your identity on Github, Twitter, Reddit, etc, by creating a signed statement and publishing it both there and on your sigchain. (You can revoke by removing either statement.)

You can search for keys by user name and service (e.g. gabriel@github, gabrlh@twitter), or lookup a user by a key identifier using a REST API.

The Saltpack format is used for signing and encryption, providing authenticity, repudability and anonymity.

The Noise Protocol is used to create a secure connection between two keys.

Key identifiers are Bech32 format, encode the type of key and public key bytes, and include a checksum with error correction.

Your keys and secrets are protected by a keyring which is secured by both the OS and a user supplied password.

The app and command line utility connect to a keysd daemon runs as a gRPC service on your computer.

The above example pulls the public key for the Github user gabriel, verifies it and creates an encrypted saltpack message.

# What else?

# Go Libraries

All the features in the app is available through Go libraries.

See some examples

# Similarities/Differences

• Keybase: This project borrows many ideas from Keybase, including sigchains and user (proofs), and uses Saltpack and keybase/go-keychain and other packages.
  However, this project only links a single key to a user.
• Age: We also use Bech32 as a key identifiers, and convert Ed25519 keys to X25519.

# Coming soon

• Other key types like age?
• Legacy/pgp?
• Better documentation
• More services (Facebook, Website)
• Inbox
• Import SSH ed25519 keys
• Wormhole through relays (syncthing)
• Syncthing integration
