lioness - LIONESS-BLAKE2b-ChaCha20

Yawning Angel (yawning at schwanenlied dot me)

Yet another Go LIONESS implementation, similar to go-lioness, though with slightly different parameterization, and support for a nonce. The implementations are NOT interoperable.

Notes:

• H() is BLAKE2b with a 256 bit key, 96 bit nonce.
• S() is ChaCha20 with a 256 bit key, 96 bit nonce.
• The crypto implementations used have assembly for AMD64.
• It's still kind of slow, because it's LIONESS, and it's written in Go.
