The Real-Time Proactive Secret Sharing Library is an implementation of the Shamir's secret sharing scheme and Herzberg's proactive secret sharing algorithm. The library targets the RTAI OS. It includes a port of GNU GMP to RTAI, which is used for multiple precision arithmetic operations.
HAVEGE (HArdware Volatile Entropy Gathering and Expansion) is a user-level software unpredictable random number generator for general-purpose computers that exploits modifications of the internal volatile hardware states as a source of uncertainty. It combines on-the-fly hardware volatile entropy gathering with pseudo-random number generation. The internal state includes thousands of internal volatile hardware states and is merely unmonitorable. It can support several hundreds of megabits per second on current workstations and PCs.
Odyssi Certificate Server is a Java-based certificate authority server, comprising the heart of the Odyssi PKI Suite. When completed, it will provide users with an enterprise-quality PKI system, with features such as LDAP publishing, CRL generation, and support for popular PKI-related protocols such as XKMS and CMP.
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.
Suhosin is an advanced protection system for PHP installations. It was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts that can be used separately or in combination. The first part is a small patch against the PHP core that implements a few low-level protections against buffer overflows or format string vulnerabilities. The second part is a powerful PHP extension that implements all the other protections. Suhosin is binary compatible with plain PHP installations.
