PyCryptoPlus
Revision as of 14:11, 1 September 2008 by <bdi>Tiftof</bdi> (talk | contribs)
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
Licenses
- used from python truecrypt implementation
all original code is under MIT license (much freedom according to [1])- pyTwofish (untouched)
python truecrypt author isn't the original author = > extra copyright notice that should be left in place - pyserpent (untouched)
python truecrypt author isn't the original author = > extra copyright notice that should be left in place - XTS (modified)
python truecrypt author is the original author => only MIT License - GF2n.py(untouched)

- pyTwofish (untouched)
- pyblowfish (untouched)
gpl or artistic license
gpl is compatible with public domain - rijndael.py (untouched)
using tls lite (public domain) implementation which uses code from Bram Cohen (public domain) - pyDes (untouched)
public domain according to its homepage - blockciphers CBC, ECB, CTR from [2] (modified)
keep copyright notice in place?
