PyCryptoPlus

TODO

add chaining modes
further importing of pycrypto
make test vectors available as variables
add tests:
- CBC for serpent, twofish, blowfish
- XTS is only tested by comparing deciphered ciphertext, not by checking ciphertext
check other implementation of Blowfish
final() method of chains
- add a cipher.final() method? pycrypto doesn't have it, but it doesn't really conflict with the pycrypto API. It will just extend it
- final() method should use padding. Choose padding function at initialization of the cipher => again: extending the API
XTS <-> XTS-AES?
XTS-AES just denotes XTS using AES cipher? Make only that one available?
add rijndael instead of only AES
