### chacha20 - ChaCha20
#### Yawning Angel (yawning at schwanenlied dot me)
Yet another Go ChaCha20 implementation. Everything else I found was slow,
didn't support all the variants I need to use, or relied on cgo to go fast.
Features:
* 20 round, 256 bit key only. Everything else is pointless and stupid.
* IETF 96 bit nonce variant.
* XChaCha 24 byte nonce variant.
* SSE2 and AVX2 support on amd64 targets.
* Incremental encrypt/decrypt support, unlike golang.org/x/crypto/salsa20.
