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 xtea4 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 do NOT guarantee that this implementation (or the base cipher) is secure. If you find bugs, please report them at https://github.com/tgates42/xtea/issues .
