lyra

README

---

Lyra is a lightweight and fast encryption tool that makes protecting your sensitive files easy.

Features

• Simple command line encryption and decryption.
  • Encrypting is as easy as entering: lyra encrypt file and to decrypting is just as simple: lyra decrypt file
• No need to worry about complex cipher options and configurations.
  • Lyra uses a single strong time tested cipher to protect your data. Your data is encrypted with AES-256-GCM which simultaneously provides data confidentiality, authenticity and integrity (see authenticated encryption).
  • Values that need to be unique and random (salt and nonce) are generated via a cryptographically secure pseudo random number generator.
• Strong GPU and ASIC resistant KDF being used to protect your passphrase.
  • Lyra uses argon2 to make dictionary attacks and brute force guessing even harder.
• Generate strong memorable passphrases via the diceware method.

Requirements (if building from source)

• Go 1.9 and above
• Go Deps for dependency management.

Dependencies

• gware for diceware passphrase generation.
• golang.org/x/crypto for argon2 and passphrase terminal.
• memguard for handling keys and plaintext secrurely in memory.
