Constants

const BlockSize = 8

BlockSize is the number of bytes in an XTEA block (for convenience.)

Functions

func Decipher

func Decipher(key Key, buf []byte) error

Decipher decrypts a buffer of data with XTEA.

func DecipherStream

func DecipherStream(key Key, r io.Reader, w io.Writer) error

DecipherStream decrypts a stream of data with XTEA.

func DecipherStreamTrimNull

func DecipherStreamTrimNull(key Key, r io.Reader, w io.Writer) error

DecipherStreamTrimNull decrypts a stream of data with XTEA and trims nulls at the end.

func DecryptBlock

func DecryptBlock(key Key, buf []byte)

DecryptBlock decrypts a single block of data. Note that XTEA blocks are 8 bytes long.

func Encipher

func Encipher(key Key, buf []byte) error

Encipher encrypts a buffer of data with XTEA.

func EncipherStream

func EncipherStream(key Key, r io.Reader, w io.Writer) error

EncipherStream encrypts a stream of data with XTEA.

func EncipherStreamPadNull

func EncipherStreamPadNull(key Key, r io.Reader, w io.Writer) error

EncipherStreamPadNull encrypts a stream of data with XTEA, inserting null bytes to meet XTEA's block alignment requirements.

func EncryptBlock

func EncryptBlock(key Key, buf []byte)

EncryptBlock encrypts a single block of data. Note that XTEA blocks are 8 bytes long.

Types

type Key

type Key [4]uint32

Key is a type for XTEA keys.
