FlexiCA is a certification authority tool. It is implemented using Java and the Eclipse Rich Client Platform. FlexiCA is extensible and supports RSA, DSA, and Elliptic Curve cryptography out of the box. Other crypto-systems may be added easily, if ASN.1 structures for encoding are available. All cryptographic functions are provided by FlexiProvider.
The LibPKI Project is aimed to provide an easy-to-use PKI library for PKI-enabled application development. The library provides the developer with all the needed functionality to manage certificates, from generation to validation. It helps developers integrate X509 digital certificates into their applications, and implement complex cryptographic operations with a few simple function calls using a high-level cryptographic API. The library constitutes the core of other OpenCA Labs Projects like the PRQP Server, the OCSP Responder, and the OpenCA-NG PKI.
Krypt is a simple application that sits in the system tray and provides easy access to the list of volumes encrypted with LUKS. It is possible to quickly decrypt, encrypt back, mount, and umount such devices. It also monitors HAL activity, and responds by showing a pop-up with password prompt. When the password is provided, KDE's media manager kicks in and does its job. Passwords for volumes can be stored either in a configuration file or in KDE Wallet.
SILC Crypto Toolkit (SCT) is a high performance multipurpose cryptographic toolkit for application programmers. It provides ciphers, hash functions, public key cryptosystems, MAC algorithms, multi-precision integers, cryptographic accelerators, an ASN.1 encoder and decoder, and many other features.
mnkPasswordKeeper is a simple password manager. The goal of this project is to permit the saving of passwords/notes on a USB key and be able to use the software on many platforms. It uses the Qt framework for GUI and XML reading. It uses Camellia from NTT as cipher. It has been run successfully on MS Windows, GNU/Linux, and Mac OS X.
