sanesigner is a high level digital signature api component. it support generating and verifying digital signatures as well as encryption and decryption using public keys, and lots of other features in between.

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.

Hash mode interface to the Keccak code package. This program illustrates the use of the Keccak permutation. Usage is much more than a hash function. The NIST compatible settings are subject to change when they publish FIPS PUB 180-5. I wrote this program when evaluating the permutation and developing tree hashing for the Intel(R) MIC architecture.

Shasummer is a SHA hashsum utility in Java. It can calculate SHA1, SHA256 and SHA512 hashes of a file or of a directory (and its subdirectories) and verify the hashes later. Shasummer has a graphical and a command-line interface.

SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.

the "Simple Password Displayer" is a multiuser password managing software based on GnuPG, so every user has his own password to decrypt/sign the container.

spule stands for "secure practical universal lecture evaluator". spule is a program to automatize the evaluation of lecture polls.

ssh host keyserver: extends the pgp web of trust to ssh host keys.

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.

Tcpconns:simple package for rapid development of multi-threaded client/server solutions (JAVA OpenJDK17+) with TLS (V1.3).

TCPFile is a friend to friend file sharing / instant messaging Java (1.6) program offering zipped and fully encrypted (RSA, AES) communication.

tinySSO is a simple Single Sign-On in Java based on a secure cookie protocol.

A PHP-GTK based GUI for truecrypt on linux. Requires PHP cli with PHP-GTK2 installed to run.

Being that Sun\'s Java Cryptography Extension (JCE) is not well-documented and has a steep learning curve, the vH Crypto API for Java is being created to abstract the procedures which are commonly used in cryptography.

For details of this cipher see; http://en.wikipedia.org/wiki/Vigenere_cipher This cipher can be broken by frequency analysis, this is a toy project, and should not be used in situations where security is important.

WEB-interface for Public key Infrastructure.

It load the current public-timestamp-block from publictimestamp.org and store it in a file to use it e.g. as a signature in an e-mail software. The project is inactive and not under development anymore.

cross-plattform user interface for gnu-pg

xhelix: python C extension implementing Helix encryption and authentication. Based on the article named "Helix: Fast Encryption and Authentication" by Niels Ferguson and Bruce Schneier, published in the Nov 2003 issue of Dr Dobbs Journal.

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

One of the project groups in Intake 6 is planning on doing a IM client which is secure. This includes messenging, file sending, picture drawing, video transmissions by far.

A smart card-based public key cryptography system based on elliptic curves, using AES for session key generation and SHA for hashing. This project will include the smart card software, terminal software, and a public key server.

A powerful, provider-based .NET CAPTCHA control with audio challenge and Microsoft Visual Studio design-time support.

This project provides a steganography tool that allows to know, use and compare the results of current steganographic techniques. It also incorporates a comprehensive set of stegoanalitics methods for images.

A multi-platform tool to convert RSA private keys between SFM format (modulus, public exponent, private exponent) and CRT format, in both ways.
