A python 3 version of XTEA

Project description

This is an XTEA-Cipher implementation in Python 3 (eXtended Tiny Encryption Algorithm).

XTEA is a small blockcipher with 8 bytes blocksize and 16 bytes Keysize (128-Bit). The algorithm is secure at 2014 with the recommend 64 rounds (32 cycles). The minimum for rounds is 38 (19 cycles). This implementation supports following modes of operation: ECB, CFB, CBC, OFB, CTR It also supports CBC-MAC

Documentation is here.


>>> from xtea3 import *
>>> key = b" "*16  # Never use this key
>>> text = b"This is a text. "*8
>>> x = new(key, mode=MODE_OFB, IV=b"12345678")  # Never reuse the IV!
>>> c = x.encrypt(text)
>>> text == x.decrypt(c)


I does NOT guarantee that this implementation is secure. If there are bugs, tell me them. The old version for Python 2 still will be updated. My GPG/PGP key: 0CB97138 (full fingerprint: 8F93 4984 3BA7 4A1C E5F2 A1BA 1338 DFDE 0CB9 7138)
