TinyCrypT

Personal-use implementations of various cryptographic algorithms (NOT INTENDED FOR PRODUCTION USE)

Algorithms

• ChaCha20-Poly1305 for combined encryption and MAC
• KangarooTwelve128 for hashing
• X25519 for elliptic-curve Diffie-Hellman key exchange
• SHA-256 and SHA-512 for hashing, ECDH, and Ed25519
• Ed25519 for EdDSA

Testing Validations

• The SHA-2 implementations pass all 586 NIST-provided test cases without memory violations (according to valgrind).
• The Ed25519 implementation passes all 1024 provided test cases without memory violations (according to valgrind).

Benchmarking

• The 64-bit implementation of Ed25519 (automatically compiled against when the target platform supports __uint128_t) is able to generate a signature in 0.086ms on an Intel Core i3-1315U processor (single core).
• The 64-bit implementation of ChaCha20-Poly1305 (automatically compiled against when the target platform supports __uint128_t) is able to encrypt, authenticate, decrypt, and verify 128MiB of data in 1.7s on an Intel Core i3-1315U processor (single core).
