Functions

func Decrypt

func Decrypt(cipherText []byte, key []byte, iv ...[]byte) ([]byte, error)

Decrypt is alias of DecryptCBC.

func DecryptCBC

func DecryptCBC(cipherText []byte, key []byte, iv ...[]byte) ([]byte, error)

DecryptCBC decrypts `cipherText` using CBC mode. Note that the key must be 16/24/32 bit length. The parameter `iv` initialization vector is unnecessary.

func DecryptCFB

func DecryptCFB(cipherText []byte, key []byte, unPadding int, iv ...[]byte) ([]byte, error)

DecryptCFB decrypts `plainText` using CFB mode. Note that the key must be 16/24/32 bit length. The parameter `iv` initialization vector is unnecessary.

func Encrypt

func Encrypt(plainText []byte, key []byte, iv ...[]byte) ([]byte, error)

Encrypt is alias of EncryptCBC.

func EncryptCBC

func EncryptCBC(plainText []byte, key []byte, iv ...[]byte) ([]byte, error)

EncryptCBC encrypts `plainText` using CBC mode. Note that the key must be 16/24/32 bit length. The parameter `iv` initialization vector is unnecessary.

func EncryptCFB

func EncryptCFB(plainText []byte, key []byte, padding *int, iv ...[]byte) ([]byte, error)

EncryptCFB encrypts `plainText` using CFB mode. Note that the key must be 16/24/32 bit length. The parameter `iv` initialization vector is unnecessary.

func PKCS5Padding

func PKCS5Padding(src []byte, blockSize int) []byte

func PKCS5UnPadding

func PKCS5UnPadding(src []byte, blockSize int) ([]byte, error)

func ZeroPadding

func ZeroPadding(cipherText []byte, blockSize int) ([]byte, int)

func ZeroUnPadding

func ZeroUnPadding(plaintext []byte, unPadding int) []byte
