Functions

func NewCipher

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

NewCipher returns an instance of the TEA cipher with the standard number of rounds. The key argument must be 16 bytes long.

func NewCipherWithRounds

func NewCipherWithRounds(key []byte, rounds int) (cipher.Block, error)

NewCipherWithRounds returns an instance of the TEA cipher with a given number of rounds, which must be even. The key argument must be 16 bytes long.
