A python version of XTEA
Project description
Python XTEA
This is an implementation of XTEA-Cipher in Python (eXtended Tiny Encryption Algorithm).
XTEA is a blockcipher with 8 bytes blocksize and 16 bytes Keysize (128-Bit). The algorithm is secure at 2014 with the recommend 64 rounds (32 cycles). This implementation supports following modes of operation: ECB, CBC, OFB, CTR (buggy)
Example:
>>> from xtea import * >>> key = " "*16 # Never use this >>> text = "This is a text. "*8 >>> x = new(key, mode=MODE_OFB, IV="12345678") >>> c = x.encrypt(text) >>> text == x.decrypt(c) True
Note
I does NOT guarantee that this implementation is secure. If there are bugs, tell me them. Python 3 support is at work. My GPG/PGP key: 0CB97138 (full fingerprint: 8F93 4984 3BA7 4A1C E5F2 A1BA 1338 DFDE 0CB9 7138)
