JSerpent is an easy to use Java implementation of the powerful Serpent cryptography algorithm. It can be easily implemented into any project, and is complete with ECB, padding, and a simple API.
JFish is a simple Java implementation of the popular Twofish cryptography algorithm. It allows any application to easily implement powerful encryption, using a single small library and minimal code changes.
JRijndael is a 100% pure Java implementation of the popular Rijndael (aka AES) cryptography algorithm. It's designed to be implemented as easily as possible and features ECB, padding, and a simple API.
The Eclipse XML-Security Plug-In allows you to experiment with the W3C recommendations on digital signatures and encryption and to learn all about their background. Arbitrary XML documents can be canonicalized, signed, verified and en- or decrypted.
aamFetch is a utility for fetching your anonymous esub nym messages from the alt.anonymous.messages newsgroup (or other newsgroups). It allows multiple encrypt-subjects to scan, multiple "destination files" to save messages to and random chaff downloads.
A java application that allows you to store files into a "data store". These files are encrypted by passphrases and padded with random garbage to provide plausible deniability (you cannot know if there are any more files in the store or not).
JEraser is a very simple but extremely effective tool to erase a file or and entire directory so that no one could recover it.
It's written in Java so you can run it on every platform.

A web search engine for the CVE dictionary, targeted to be used on a intranet.
CVEBrowser uses Java Servlets / JSP and MySQL and its designed to work well on RedHat
crcRepair is a utility that is able to fix corrupt files by consulting a database and file mirrors. It is written in pure Java, so it can be used on all platforms with the Java JRE installed.
Please note: not having time to complete jSai myself; I came across the ACEGI project which I now recommend instead.
jSai; a Servlet Authentication Implementation. jSai aims to allow easier to use, more powerful authentication for Java Servlets.
Secrets is a complete, standalone, personal encryption solution that works much like PGP (Pretty Good Privacy). With Secrets you can encrypt information before emailing it to a friend or coworker, or before storing it on a removable disk. Secrets is buil
VPNmonitor is a Java tool for network administrators to monitor VPN and SSL connections. The graphical representation makes it easy to visualize messages between computer nodes. Users can also read messages not of the above types in plain text.
The MuPPIT is cross-platform, open source Multi-Purpose Peons Internet Toolkit written in Java and C++, providing a collection of new, useful applications for the average internet user.
Simple Encoder/Decoder, written in the .net framework.
It is basicly an encryption program which supports serveral encryption methods.
It can encode or decode texts in the forms of files or just plain text written directly in the program.
OpenSST (Open Simple Secure Transaction) is a project to create a simple security protocol for making transaction between (un)trusted parties. The project includes a protocol design specification and a cross-platform software implementation of the speci
