KNoFault is a tool that protects your files with XOR encryption. It can use a username and a password to encrypt, or it can any file as a key. When given an incorrect decryption key, instead of showing an error it will encrypt the already encrypted file with the new info. This makes it possible to encrypt a file several times so that only two people together can use it, for example.
YOURI (Youri Offers an Upload & Repository Infrastructure) aims to build tools that make the management of a coherent set of packages easier. It assists in the many tasks involved with running a package distribution project, such as allowing individual maintainers to upload packages in a central repository, creating package indexes for package, synchronizing development resources such as CVS or bugzilla, advertising new packages, signing packages, and checking the consistency of individual packages or the global repository.
