Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.
The main philosophy of the project is "the best protection a bad password can give". People will choose bad password as long as they have this option, so Neocryptex builds a strong crypographical defence between the password and encrypted data.
stores a free text field strongly encrypted on a cell-phone or PDA using AES encryption with 256 bit -- can be used for storing passwords, pins and other sensitive data

BarTex is a system designed to create inexpensive tickets for events. It uses a crypto system to verify tickets using barcodes; thus eliminating the cost of expensive, colorful tickets that cannot be photocopied/forged.
a small library for cryptography (e.g. for the MicroEdition of Java) that supports AES (256 bit only), SHA-512 and CBC. The library is available in Java and JavaScript.
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.
Hash Cracker is an application developed in java swings that allows a user to crack MD2, MD5, SHA-1,SHA-256,SHA-384,SHA-512 hashes either using brute force or using wordlists of the user's choice based on the users choice.

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.
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.
HashserGUI is a GUI interface for Jacksum. It is intended to provide a graphical tool to create hashes for files within a directory, and check the hashes generated. It works with many hash functions, as md5, sha1, sha256, sha512, md4, crc, etc.
An implementation of Shoup's "Practical Threshold Signature" in Java. This is an (n,k)-threshold signature system: at least k parties out of n must independently sign a piece of data to produce a valid group signature.
Encryption plugin for Alfresco. Enables the user to crypt and decrypt (it handles the 'pkcs5' MIME-type). This is a component of the IDX-eDOC project (OpenTrust suite), contributed by IDEALX
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.
INTIX-JSIGNER is a java web application for signing documents (XML and/or PDF) of unattended way and in the server side. It has as main modules the following: Authentication, XML and PDF Signing and Keys and Certificates Management.
The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.
