block.go cipher.go const.go

Constants

const BlockSize = 8

The DES block size in bytes.

func NewCipher Uses

func NewCipher(key []byte) (cipher.Block, error)

NewCipher creates and returns a new cipher.Block.

func NewTripleDESCipher Uses

func NewTripleDESCipher(key []byte) (cipher.Block, error)

NewTripleDESCipher creates and returns a new cipher.Block.

Code:play 

// NewTripleDESCipher can also be used when EDE2 is required by
// duplicating the first 8 bytes of the 16-byte key.
ede2Key := []byte("example key 1234")

var tripleDESKey []byte
tripleDESKey = append(tripleDESKey, ede2Key[:16]...)
tripleDESKey = append(tripleDESKey, ede2Key[:8]...)

_, err := des.NewTripleDESCipher(tripleDESKey)
if err != nil {
    panic(err)
}

// See crypto/cipher for how to use a cipher.Block for encryption and
// decryption.

type KeySizeError Uses

type KeySizeError int

func (KeySizeError) Error Uses

func (k KeySizeError) Error() string
