Visual Cryptography and Bit-Plane Complexity Segmentation in Python
Hide secret messages in your pictures!
Cyberbit lets you transmit a secret message to an intended person in a new manner.
The secret message is an 1-bit deep black & white image. The message can contain
written text, a drawing, a secret code etc. Using Visual Cryptography the
application splits the secret message into two "shadow images" called <<shares>>.
Any of the two shares will be embedded into a "normal" image file called by tradition
<<vessel>>. You can use a method of hand to...
Go to github.com/vlm/asn1c for the latest version.
This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the sourcecode distribution.
NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c
SSL-Explorer is a fully-featured, web-based SSL VPN server. This project is no longer actively maintained as the SSL-Explorer technology has now been acquired by Barracuda Networks, Inc.
PHPki is an Open Source Web application for managing a multi-agency PKI for HIPAA compliance. With it, you may create and centrally manage X.509 certificates for use with S/MIME enabled e-mail clients, SSL servers, and VPN applications.
Using encryption to secure your code or text. Click File->Run to run your code using Ruby, see the pop up for output. Never save your text or code to disk unencrypted. Don't forget your password. Encryption is error-persistent.
This is where web developers can get tools that can make their life easier. Web technologies and languages used contain but are not limited to HTML, XHTML, CSS, JavaScript, PHP, and AJAX. All code is extremely slim, fast running, and is W3C compliant.
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)
Finds Text in Delphi *.Pas files e.g. : button1.caption:='Hello'
Replaces Text with a function call button1.caption:=TXT(0) {##Hello##}
Generates a function „TXT“ with a String List with all found Texts at the beginning of your source.
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.

Libraries and tools written in .NET managed code (MS/mono) to interact with GRC's Perfect Paper Password system [https://www.grc.com/ppp.htm] Source moved to GitHub: http://github.com/ErebusBat/pppNET
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.
siggen is a cool email signature generator for encrypted ansi c (confused), brainf*ck, ... signatures. Use it in combination with vi(m), emacs, mutt, pine, or what ever. (tested on Solaris, Linux and Windoze). Optimized only for geeks :-)

The FreePKI project aims to create practical, interoperable & free code and services for Certificate and Registration Authorities based on the X.509 standard, including nearly zero-cost ID verification through a PGP-like web of trust scoring system.
The goal of Operation Project X is to crack the 2048-bit RSA private encryption key Microsoft uses to sign Xbox media, by using distributed computing. This key could be used by Xbox owners to run homebrew code on their machines.
bcrypt is a lightweight blowfish file encryption utility which aims for cross-platform portability of not only the actual code, but the encrypted files as well. In addition to providing 448-bit encryption, bcrypt overwrites input files with random garbage
The SLAN project is a GPL open-source project providing a cross platform Virtual Private Networking (VPN) solution focused on providing secured and accountable links over insecure broadcast media such as 802.11 wireless LANs and public ethernets.
Yavipind is a secure tunnel aka 2 peers securely forwarding
packets toward each other.It is what most people calls a VPN (virtual private
network).
It forwards any kind ofpacket (IPv4, IPv6 or other) sent over the virtual
network interface (e.g. t
