The free password manager for power users

freepass

The free password manager for power users.

What's going on?

• A password manager.
• Based on the Master Password algorithm, generates the same passwords as the Master Password apps.
• But wait, there's more! Why stop at passwords? It generates...
  • Ed25519 digital signature keys for...
    • OpenSSH: Freepass adds private keys directly to a running ssh-agent & exports public keys in OpenSSH format!
    • signify: Freepass signs files & exports public keys in signify format!
    • TODO SQRL
  • Raw 256-bit keys for symmetric ciphers.
  • TODO BIP39-compatible passphrases.
• Yes, all of the above is derived from your master password and full name, you can always recover it by entering the same data!
• The generator settings (site names, counters) are stored in vault files:
  • Serialized into CBOR.
  • Encrypted with NaCl secretbox for each entry + AES for the whole file.
  • (Keys are derived from the master password like the generated passwords.)
  • Every time you save a vault file, its size changes randomly. That's a feature. Some random junk is added to make it a bit harder to count how many passwords you have without opening the file.
• You can also store passwords and text in these vault files (for stuff that can't be generated).
• You can merge two vault files (e.g. from sync conflicts).
• You can import KeePass 2 (kdbx) files.

How?

• Freepass is written in the Rust programming language and uses libsodium as the crypto library.
• Very modular code, easy to audit.
  • You can separately check that the core library does everything correctly, and that the user interface passes your data to the core library, not to an evil server.
• Some parts were written as completely separate Rust crates:
  • secstr: secure strings
  • interactor: user interface things for the cli version
  • colorhash256: Chroma-Hash-style color feedback for password input
  • rusterpassword: the Master Password algorithm implementation
• Completely free software: public domain / Unlicense.

Where?

Freepass is (going to be) available on different platforms:

• cli: for UNIX-like systems
• A desktop GUI and mobile apps will be available in the future.

Each version has its own README!
