PurrCrypt is a command-line encryption tool with an intentionally playful presentation. It encrypts files using public-key cryptography and then represents the resulting data as patterned cat or dog sounds such as meows, purrs and barks.
The animal-sound layer is an encoding applied around the encrypted data rather than a substitute for cryptography. Users create their own key pair, exchange public keys with recipients and keep the private key protected. Anyone who recognises PurrCrypt’s format can identify the output, so the themed representation should not be treated as anonymity.
This is free and open source software.
Key Features
- Generates named public/private key pairs for encrypting files to specific recipients.
- Imports other users’ public keys and maintains a local list of known recipients.
- Uses the secp256k1 elliptic curve for its public-key cryptographic operations.
- Encrypts arbitrary files and writes the protected result to a separate PurrCrypt file.
- Decrypts received files with the matching private key and writes the recovered plaintext to a chosen path.
- Offers separate cat and dog dialects, each mapping encrypted binary data into its own vocabulary and repetition patterns.
- Lets users set a default dialect or choose an encoding style for an individual encryption operation.
- Includes library interfaces for Rust programs that want to use its cryptographic and animal-encoding components.
