Types

type AESKey

type AESKey struct {
	// contains filtered or unexported fields
}

AES a AES instance is a tool to encrypt and decrypt

func (*AESKey) Bytes

func (ek *AESKey) Bytes() ([]byte, error)

Bytes return bytes

func (*AESKey) Decrypt

func (ek *AESKey) Decrypt(crypted []byte) ([]byte, error)

Decrypt decrypt

func (*AESKey) Encrypt

func (ek *AESKey) Encrypt(plain []byte) ([]byte, error)

Encrypt encrypt

func (*AESKey) Type

type ThirdDESKey

type ThirdDESKey struct {
	// contains filtered or unexported fields
}

TripleDES a 3DES instance is a tool to encrypt and decrypt Very not recommended to use 3des!!! It's slow and unsafe
