Stegger is a PHP package that can be used to hide encrypted data in images using steganography. It reads a given image in GIF, JPEG, or PNG formats, encrypts data supplied by the user (a message, a file, or a collection of both) and hides the encrypted data in the image by making subtle color changes to certain pixels to store the data in the image symbolically. It can also extract the original data previously stored in an image.
iSSL (independant Secure Sockets Layer) is a minimalistic cryptographical API that uses the RSA and AES ciphers to establish SSL-alike, secure encrypted communications between two peers communicating through a network socket, including session key generation and public key exchange.
CAKE (Key Addressed Crypto Encapsulation) is a bunch of Python and C++ for implementing the CAKE protocol. The CAKE protocol is a protocol in which all messages have source and destination addresses that are public keys. This is in the same way that IP packets have a source and destination address that is an IP address.
Lost in Translation is a steganographic encoder that exploits the possibilities of steganographically embedding information in the "noise'' created by automatic translation of natural language documents. Because natural language translation inherently creates plenty of room for variation, it is ideal for steganographic applications. Also, because there are frequent errors in legitimate automatic text translations, additional errors inserted by an information hiding mechanism are plausibly undetectable and would appear to be part of the normal noise associated with translation.
keyanalyze is designed to analyze keyrings in the OpenPGP format (PGP and GnuPG). It looks at properties of connectivity to generate strongly-connected set analysis, as well as some arbitrary statistics including a "mean shortest distance" calculation to show the most connected keys. This code is also used to create a report based on an extremely large keyset once per month.
