libkrypton

libkrypton is my toy cryptography library.

Security

It's strongly recommended to never use this, as it's completely unaudited. Theoretically, it should be correctly implemented and resistant against side-channel attacks such as timing attacks.

Algorithms

libkrypton implements various algorithms including:

• ChaCha20, a 256-bit strong stream cipher and pseudorandom entropy source
• Poly1305, a ~100-bit strong MAC / authenticator
• X25519, a 128-bit strong Diffie-Hellman key exchange over the Curve25519 elliptic curve
