        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 = " "*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

        Changelog
        ---------
        
        Version 0.7.1, former 0.6.1 / 0.7.0; Jun 16, 2018
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        - Improved tests
        - PEP8-style formatting
        - Unittests: Counter, modes (but not results of them!), test vectors
        - [BREAKING CHANGE] Counter class is now in xtea.counter
        - Python 3.3 is not tested anymore on Travis CI
        - [BREAKING CHANGE] CFB mode is now correctly implemented.
          By setting ``partition_size`` it is possible to set the
          internal partition size (in bits) as per PEP-272.
        - Python 3: An optional C extension improves speed upto a factor of 10.
        - [BREAKING CHANGE] `block_size` and `key_size` is now in bytes.
        - Skipped 0.7.0 with
