Cyberbit
Visual Cryptography and Bit-Plane Complexity Segmentation in Python
...Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. ... -

PyEvcs
Extended Visual Cryptography Schemes in Python
Visual Cryptography is a graphical form of information concealing. In a 2-out-of-2 Visual Cryptography Scheme a dealer will "split" a secret image into two shares, print the shares onto separate transparencies and hand them to the participants to the scheme. If the two participants come together, they'll be able to reveal the secret image without a computer, perfectly superimposing the transparencies they own. -

FactHash
Factorial Hashing Function
My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's... -

tickets
pythonic kerberosish ticket system: easy to use, easy to subclass
A SecureTicket, or Ticket, consists of salt, hash, valid_until, public_flags, flags, data and "invisible" hashed entropy. Tickets are symmetrically signed using SHA256-HMAC. Fields 'valid_until', 'flags' and 'data' may be optionally encrypted using AES128-CBC or TripleAES128-CBC. Values 'data' and 'entropy' may consist of arbitrary objects which are transparently pickled(serialized), optionally gzipped and of course securely signed. Specific implementations are included: FormTicket:... -
