Functions

func NewGCM

func NewGCM(cipher cipher.Block) (*gcm, error)

NewGCM returns the given 128-bit, block cipher wrapped in Galois Counter Mode with the standard nonce length.

func XorBytes

func XorBytes(dst, a, b []byte) int

xorBytes xors the bytes in a and b. The destination is assumed to have enough space. Returns the number of bytes xor'd.
