FileVerifier++ is a Windows utility for calculating hashes using a number of algorithms including CRC32, MD5, SHA-1, SHA-256/224/384/512, WHIRLPOOL, and RIPEMD-128/160/256/320. Supported hash file formats include MD5SUM .MD5, SFV, BSD CKSUM, and others.

Seahorse is a Gnome front end for GnuPG. It is a tool for secure communications and data storage. Data encryption and digital signature creation can easily be performed through a GUI, and Key Management operations also can be performed.

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

The JWA library aims to provide a conversion from C to Delphi of as many headers as possible from the PSDK etc. The JWSCL (security library) is an advanced object-oriented framework for programming with the Windows security features (ACL, Tokens, etc.)
