Package xtea
import "crypto/xtea"
Package xtea implements XTEA encryption, as defined in Needham and Wheeler's 1997 technical report, "Tea extensions."
Package files
block.go cipher.goConstants
The XTEA block size in bytes.
const BlockSize = 8
type Cipher
A Cipher is an instance of an XTEA cipher using a particular key. table contains a series of precalculated values that are used each round.
type Cipher struct {
// contains filtered or unexported fields
}
func NewCipher
func NewCipher(key []byte) (*Cipher, os.Error)
NewCipher creates and returns a new Cipher. The key argument should be the XTEA key. XTEA only supports 128 bit (16 byte) keys.
func (*Cipher) BlockSize
func (c *Cipher) BlockSize() int
BlockSize returns the XTEA block size, 8 bytes. It is necessary to satisfy the Cipher interface in the package "crypto/cipher".
func (*Cipher) Decrypt
func (c *Cipher) Decrypt(dst, src []byte)
Decrypt decrypts the 8 byte buffer src using the key k and stores the result in dst.
func (*Cipher) Encrypt
func (c *Cipher) Encrypt(dst, src []byte)
Encrypt encrypts the 8 byte buffer src using the key 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 (*Cipher) Reset
func (c *Cipher) Reset()
Reset zeros the table, so that it will no longer appear in the process's memory.
type KeySizeError
type KeySizeError int
func (KeySizeError) String
func (k KeySizeError) String() string
