Overview ¶
Package des implements the Data Encryption Standard (DES) and the Triple Data Encryption Algorithm (TDEA) as defined in U.S. Federal Information Processing Standards Publication 46-3.
DES is cryptographically broken and should not be used for secure applications.

Functions ¶
func NewTripleDESCipher ¶
NewTripleDESCipher creates and returns a new cipher.Block.
Example ¶
// 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]...)
l := log.Default
l.HexDump("tripleDESKey", tripleDESKey)
_, err := NewTripleDESCipher(tripleDESKey)
if err != nil {
panic(err)
}
// See crypto/cipher for how to use a cipher.Block for encryption and
// decryption.
