Functions

func HChaCha20

func HChaCha20(out *[32]byte, nonce *[16]byte, key *[32]byte)

HChaCha20 generates 32 pseudo-random bytes from a 128 bit nonce and a 256 bit secret key. It can be used as a key-derivation-function (KDF).

func New

func New(key []byte) (cipher.AEAD, error)

New xChaChapoly1305 AEAD with 24 byte nonces
