func ComputeRawMAC1 ¶

func ComputeRawMAC1(key, data []byte) ([]byte, error)

func ComputeRawMAC3 ¶

func ComputeRawMAC3(key1, key2, data []byte) ([]byte, error)

func Pad00 ¶

func Pad00(data []byte, blockSize int) []byte

Pad00 is an alias to PadBytesMethod1

func Pad80 ¶

func Pad80(data []byte, blockSize int) []byte

Pad80 is an alias to PadBytesMethod2

func PadBytesMethod1 ¶

func PadBytesMethod1(data []byte, blockSize int) []byte

PadBytesMethod1 adds bits with value 0 to the end of the data until the padded data is a multiple of n. If the original data was already a multiple of n, no bits are added.

func PadBytesMethod2 ¶

func PadBytesMethod2(data []byte, blockSize int) []byte

PadBytesMethod2 pads the data with byte 0x80 and then 0x00s until the data is an exact multiple of the block size. When the data size is already a multiple of the block size, nothing will be added

func UnpadBytesMethod2 ¶

func UnpadBytesMethod2(data []byte) ([]byte, error)
