Keyczar is a cryptographic toolkit designed to make it easier and safer for developers to use cryptography in their applications. It supports authentication and encryption with both symmetric and asymmetric keys. Cryptography is easy to get wrong. Developers can choose improper cipher modes, use obsolete algorithms, compose primitives in an unsafe manner, or fail to anticipate the need for key rotation. Keyczar abstracts some of these details by choosing safe defaults, automatically tagging outputs with key version information, and providing a simple programming interface.
LibRCrypt is an Objective C library for complex data encryption based on Rubik's Cubes. The idea's pretty simple: If you represent data as the squares on a Rubik's Cube, you can apply transformations to the data and get back encrypted data, all of which is commutatitive. Just as a Rubik's Cube can be solved if you know all of the moves, this data can be "unwound", so to speak, if you know all of the transforms applied, but the encryption is even deeper than that. A cube can only cover (9 squares per face x 6 faces) 54 significant bits of data. Therefore, compressed data must be composed of multiple (even thousands) of Rubik's Cubes.
OpenXPKI is a Web and CLI-based enterprise-grade PKI/trust center system (X509 public key infrastructure) complete with CA, Web interfaces, offline support, and support for well established infrastructure components like RDBMS and Hardware Security Modules. Flexibility and modularity are the project's key design objectives. Unlike many other PKI solutions, it offers powerful features necessary for professional environments. However, small scale installations are also targeted by providing quick-start configuration examples that allow you to get a usable PKI running quickly.
The Secure Storage service for the gLite middleware provides users with a set of tools for storing data securely and in an encrypted format on the grid storage elements. Data is accessible and readable by authorized users only. Moreover, it solves the insider abuse problem by also preventing administrators of the storage elements from accessing the confidential data in a clear format. The service has been designed and developed for the grid middleware of the EGEE Project, gLite, in the context of the TriGrid VL Project.
Sleutel is a multi-platform password manager that is written using the Eclipse Rich Client Platform (RCP). Its goal is to manage password/ID pairs for accessing Web sites and to provide an example RCP application. It features configurable password generation, labeling of password entries (a la GMail), an intuitive UI following the Eclipse model, merge capabilities, and the ability to track usage count and dates of password entries. Sleutel is the Dutch word for key.
