Functions

func NewCipher

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

NewCipher creates a 128-bit Grain128-AEAD AEAD.

Grain128-AEAD must not be used to encrypt more than 2^80 bits per key, nonce pair, including additional authenticated data.

func NewStreamCipher

func NewStreamCipher(key, nonce []byte) (cipher.Stream, error)

NewCipher creates a Grain128a stream cipher.

Grain128a must not be used to encrypt more than 2^80 bits per key, nonce pair.
