Implement PKCS#7 padding with block size of 16 (AES block size). AddPKCSPadding adds padding to a block of data.

(src []byte)

// AddPKCSPadding adds padding to a block of data.
func AddPKCSPadding(src []byte) []byte {
	padding := aes.BlockSize - len(src)%aes.BlockSize
	padtext := bytes.Repeat([]byte{byte(padding)}, padding)
	return append(src, padtext...)
}

// RemovePKCSPadding removes padding from data that was added with addPKCSPadding.
func RemovePKCSPadding(src []byte) ([]byte, error) {
