Documentation¶
Overview¶
Package des implements the Data Encryption Standard (DES) and theTriple Data Encryption Algorithm (TDEA) as definedin U.S. Federal Information Processing Standards Publication 46-3.
DES is cryptographically broken and should not be used for secureapplications.
Index¶
Examples¶
Constants¶
const BlockSize = 8The DES block size in bytes.
Variables¶
This section is empty.
Functions¶
funcNewCipher¶
NewCipher creates and returns a newcipher.Block.
funcNewTripleDESCipher¶
NewTripleDESCipher creates and returns a newcipher.Block.
Example¶
package mainimport ("crypto/des")func main() {// 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 []bytetripleDESKey = 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.}
