=== Python ===

Es existieren zwei Packages:
  - ''pip install pycryptopan'' - funktioniert nicht, Python2?
  - ''pip install yacryptopan'' - funktioniert auch mit IPv6
     - https://github.com/keiichishima/yacryptopan 

<code Python>
>>> from yacryptopan import CryptoPAn
>>> cp = CryptoPAn(b'32-char-str-for-AES-key-and-pad.')
>>> cp.anonymize('192.0.2.1')

# Test the key from the C++ reference implementation:
>>> a = (21,34,23,141,51,164,207,128,19,10,91,22,73,144,125,16,216,152,143,131,121,121,101,39,98,87,76,45,42,132,34,2)
>>> c = bytes(a)
>>> cp = CryptoPAn(c)

# Test the randomness for the first oktett
for i in range(0,256):
...   s = (str(i)+".1.1.1")
...   print(s + " -> ", end=""); cp.anonymize(s)
