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.
Index ¶
Constants ¶
const BlockSize = 8
The DES block size in bytes.

Functions ¶

Types ¶
type Cipher ¶
type Cipher struct {
// contains filtered or unexported fields
}
Cipher is an instance of DES encryption.
type KeySizeError ¶
type KeySizeError int
func (KeySizeError) String ¶
func (k KeySizeError) String() string
type TripleDESCipher ¶
type TripleDESCipher struct {
// contains filtered or unexported fields
}
A TripleDESCipher is an instance of TripleDES encryption.
func NewTripleDESCipher ¶
func NewTripleDESCipher(key []byte) (*TripleDESCipher, os.Error)
NewCipher creates and returns a new Cipher.
func (*TripleDESCipher) BlockSize ¶
func (c *TripleDESCipher) BlockSize() int
BlockSize returns the TripleDES block size, 8 bytes. It is necessary to satisfy the Block interface in the package "crypto/cipher".
func (*TripleDESCipher) Decrypt ¶
func (c *TripleDESCipher) Decrypt(dst, src []byte)
Decrypts the 8-byte buffer src and stores the result in dst.
func (*TripleDESCipher) Encrypt ¶
func (c *TripleDESCipher) Encrypt(dst, src []byte)
Encrypts the 8-byte buffer src and stores the result in dst. Note that for amounts of data larger than a block, it is not safe to just call Encrypt on successive blocks; instead, use an encryption mode like CBC (see crypto/cipher/cbc.go).
func (*TripleDESCipher) Reset ¶
func (c *TripleDESCipher) Reset()
Reset zeros the key data, so that it will no longer appear in the process's memory.
