StrongKey CryptoEngine (SKCE) 2.0 is a "crypto Swiss Army knife" server to perform cryptographic functions through web services, while freeing application developers to focus on business functionality. Its modules include: - A FIDO Engine to support FIDO U2F key registrations/authentications - An encryption engine to encrypt/decrypt files using AES/TDES keys - Escrowing keys to on-premises key management system (StrongAuth KeyAppliance/SAKA) - Integration to cloud storage services (AWS S3, Azure and Eucalyptus Walrus) - A signing engine to digitally sign documents, code, etc. with FIPS 140-2 HSM support - An LDAP Engine for AD/LDAP integration for authorization decisions SKCE is battle-tested and in production at one of the largest e-commerce companies in the world, protecting more than 50M documents within the business process; see http://bit.ly/14VPYlO for the case study. Download StrongKey CryptoCabinet (SKCC) on this site to see how to use SKCE.

A 100% pure Java Swing ASN.1 analysis utility for inspecting arbitrary BER-encoded data files. It allows inspection of data with unknown structure, can drill down to any nesting level and allows to interpret embedded OCTET STRING data recursively.

Java class file encryption. Class Encrypt is a program that can encrypt a developer's class files and package them into an executable jar file for deployment. The program uses modules for implementing different encryptions.

Commons-SSH is a thin bridge between different Java SSH implementations libraries. It doesn't contain any crypto-related code and created to be used by projects who doesn't want to care about export control regulations (let client to decide)

This is a JavaScript library which gives the ability to use cryptographic functionality abstracted of available technologies on the browser side. It executes a cryptographic function with the fastest technology including Java, JavaScript and Flash.

CryptoPad is a Java based file encryptor ! It can encrypt every type of file. The icing on the cake is that it's 100% cross-platform. i.e. You can run the same .jar file on Windows, Mac OS, Linux and any OS capable of running JRE 8 :) CryptoPad uses AES-128 bit symmetric key encryption to secure your data.

TextConverter is a graphical text editor allowing the user to encrypt/decrypt the textual contents displayed on the screen using a 128-bit AES (Advanced Encryption Standard) cipher.

Pure-Java cryptographic calculator, featuring basic arithmetic operators, cryptographic operations, multiple key file formats and edition of ASN.1 object files.

A collection of useful Java classes.

This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

GiANT is a graphical interface for computer algebra systems (OS X/UNIX/Win). Currently GiANT lets the user work with number fields via KASH, but we aim to develop it into a GUI Library to run on top of any CAS and expose any of its functions.

HTMF is a Java Hard Token Management Framework used to manage the complete livecycle of an organizations Smartcards and/or USB dongles. It communicates with the tokens through a PKCS11 interface.

Composed of a Java steganographic library and GUI to use steganography. Primarily intended for research communities on security and steganography to implement new dissimulation and steganalysis algorithms. More information at www.hidereveal.org

Identityflow provides a framework for building protocol flows that perform distributed Identity operations. Examples of Identity Operations are Single Sign-On (SSO) and Attribute queries.

The J-WASTE project aims at the implementation of a platform independent client/server Java implementation of the WASTE protocol. This project started as a mandatory project course in networking at the Luleĺ University of Technology in Sweden.

This project provides an interface to Sun's JCE (Java Cryptographic Extensions) as a JSP taglib. It brings strong encryption algorithms such as AES and Blowfish to your JSP applications. It uses the bouncycastle.org cleanroom JCE 1.2.1 implementation as

JConfigura is a library usable in java environments for sharing configuration parameters between different java applications. Moreover it exculpates developers of aspects like property file reading and securing property files with rsa encryption.

Jssltrace is a java-based tool, which enables it's user to intercept ssl based communication between two programs. Jssltrace works essentiallly in the same manner as tcptrace (http://www.pocketsoap.com/tcptrace), which is the main inspiration for it.
