Functions ¶

func NewCipher ¶

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

NewCipher creates and returns a new cipher.Block. The key argument should be the RC5 key, the wordSize arguement should be word size in bits, the r argument should be number of rounds.

func NewCipher16 ¶ added in v1.0.2033

func NewCipher16(key []byte, r uint) (cipher.Block, error)

NewCipher16 creates and returns a new cipher.Block with 16 bits word size. The key argument should be the RC5 key, the r argument should be number of rounds.

func NewCipher32 ¶

func NewCipher32(key []byte, r uint) (cipher.Block, error)

NewCipher32 creates and returns a new cipher.Block with 32 bits word size. The key argument should be the RC5 key, the r argument should be number of rounds.

func NewCipher64 ¶

func NewCipher64(key []byte, r uint) (cipher.Block, error)

NewCipher64 creates and returns a new cipher.Block with 64 bits word size. The key argument should be the RC5 key, the r argument should be number of rounds.

Types ¶

type KeySizeError ¶ added in v1.0.2033

type KeySizeError int

KeySizeError

func (KeySizeError) Error ¶ added in v1.0.2033
