Functions

func Pad 

func Pad(data []byte, blockLen int) ([]byte, error)

Pad appends padding to the given buffer such that the resulting slice of bytes has a length divisible by the given size. If you are using this function to pad a plaintext before encrypting it with a block cipher, the size should be equal to the block size of the cipher (e.g., aes.BlockSize).

func Unpad 

func Unpad(data []byte, blockLen int) ([]byte, error)

Unpad returns slice of original data without padding. It checks the correctness of the padding bytes in constant time, and returns an error if the padding bytes are malformed.
