Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store & categorize your passwords, which are encrypted using the blowfish algorithm. It can launch applications using the host names, user names, and passwords you supply.
Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.
wlfXchanger is a point-to-point communication software which enable developers to cooperate in a secure way, using an asymmetric encryption system (Public Key Cryptography).
B-Trust eDoc is a program built on top of LibDigiDoc a free implementation of the OpenXAdES standard for signing/encrypting files using smartcard tokens. It also contains Openssl and PKCS11 wrapper classes in C++ which might be useful to developers.
distDES is a Java RMI-based application which manages load balancing on heterogeneous clusters. Development will extend the theoretical initial implementation to include clustered Rainbow Table generation and encryption algorithm collision detection.
AED Ž (Arash's Encryption/Decryption) is a perfect software for encrypting/decrypting any kind of files using a "Password" (which is optional and you can enter an space in the password field.) and a "Digital Key" which is a necessary file.
NoFault is a library written in C used to encrypt or decrypt data with XOR encryption. KNoFault, NoFault32 and CLNoFault are direct applications of the library, which is easy to use in your own programs.
An almost complete one-time-pad suite. Has many features which are non-existant in other OTP programs, and includes 5 programs (plus an uninstaller) which allow the user to create keys, create fake keys, encrypt, and decrypt files.
IMPORTANT -- This is an old project that is no longer supported and should not be relied upon for serious applications. If your looking for encryption software, I suggest OpenSSL or GnuPG which are better equipped.
