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.
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.

phpCA is a PHP-based framework to operate a certificate authority (CA). It uses the openssl functions of PHP to generate CSRs and X.509-certificates as well as mySQL to store these data.
AES.g is a port of the Advanced Encryption Standard (or Rijndael) to the GPU using a mix of C++ and Cg programming languages. It is portable and built as a class-based program, using OpenGL or DirectX libraries.
Merovingian is very easy to use but powerful GUI interface for GnuPG. It intends to be well integrated with GNOME, but still usable with other desktop environments too.
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.
PHP script to protect DIV content (e.g. private data) from indexation by bots, spammers etc...The content is encrypted in the source and decrypted by entering the key in the CAPTCHA.
OpenVPN Key Distribution System allows a web server and a OpenVPN server to exist at the edge of a network and gives a reliable system for passing out openVPN keys to the user base using ssl and php5.
Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).
Stegeek is very simple tool, that takes several files,encrypt, and mix them into one file. Also add some redundancy. The result is, that we have one archive and N keys. It should not be possible to guess N, if you have archive and up to N-1 keys.
Waste.net is a .NET-driven application geared towards providing a secure online encrypted file-sharing service. This is a purely managed .NET 2.0 port of the original Waste client/server.
Powerful 512bit pseudo random encryption, optimized for the x86-64 architecture. Coded in x86-64 assembly language, this has the potential to be one of the most powerful and fastest file encryption engines to date.
MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may however be used in any domain where efficient integer, modular, and floating-point computations involving large numbers are required.
A simple, secure and free tool for encryption and signature for Microsoft Windows and Unix. Part of the IDEALX "OpenTrust" suite (IDX-PKI, IMC, IDX-smbldap-tools...), it provides confidentiality and security through X.509-PKCS certificates. Languages:
secureDATA is a simple and easy to use encrypted personal information manager. It can store both textual information (passwords, usernames, electronic receipts, etc), and (as of v1.6) files. It uses AES-128 encryption via the Python Cryptography Toolkit.
MUSASH provides a utility to digest text, file and a byte char. It also able to compare two files, compare file, text and char to a hash. It also allows user to search for a string that evaluates to a hash given. Supported algo: MD5, SHA1 and SHA2 family
B-Trust eDoc is a program built on top of LibDigiDoc a free implementation of the OpenXAdES standard for signing/encrypting files using smartcard tokens. It also contains Openssl and PKCS11 wrapper classes in C++ which might be useful to developers.
The Password Auditing Project will be a compilation of other, previously released password auditing programs, in such a fashion as to reap the best benefits of each portion. Pulling innovations from John the Ripper, Lepton, Rainbow Tables, and more.
The OpenSSL shell/batch script collection offers insight in how to setup a hierarchical PKI structure consisting of a Root CA, several sub CA's and end entity digital certificates. The scripts are available for unix and windows.
