Overview ¶
Package xtea implements XTEA encryption, as defined in Needham and Wheeler's 1997 technical report, "Tea extensions."
Index ¶
Constants ¶

Types ¶
type Cipher ¶
type Cipher struct {
// contains filtered or unexported fields
}
A Cipher is an instance of an XTEA cipher using a particular key.
func NewCipher ¶
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 ¶
BlockSize returns the XTEA block size, 8 bytes. It is necessary to satisfy the Block interface in the package "crypto/cipher".
func (*Cipher) Decrypt ¶
Decrypt decrypts the 8 byte buffer src using the key and stores the result in dst.
func (*Cipher) Encrypt ¶
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).
type KeySizeError ¶
type KeySizeError int
func (KeySizeError) Error ¶
func (k KeySizeError) Error() string
