This is an XTEA-Cipher implementation 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, CFB, OFB, CTR
Example:
>>> from xtea import * >>> key = b" "*16 # Never use this key >>> text = b"This is a text. "*8 >>> x = new(key, mode=MODE_OFB, IV=b"12345678") # IV's must be unpredictable >>> c = x.encrypt(text) >>> text == new(key, mode=MODE_OFB, IV=b"12345678").decrypt(c) True
