Open Source Perl Cryptography Software

The OpenCA PKI Development Project is a collaborative effort to develop a robust, full-featured and Open Source out-of-the-box Certification Authority implementing the most used protocols with full-strength cryptography world-wide.

WEPCrack is a tool that cracks 802.11 WEP encryption keys using the latest discovered weakness of RC4 key scheduling.

IKECrack is an IKE/IPSec crack tool designed to perform Pre-Shared-Key [password] analysis of RFC compliant aggressive mode authentication.

Live Security/Forensics Linux Distribution, built from scratch and packed full of tools useful for vulnerability analysis, penetration tests, and forensic analysis.

pgpenvelope is an interface between Pine and the GNU Privacy Guard (GnuPG). It allows one to perform expected OpenPGP-related operations on messages. Ease of installation, setup, and use are distinguishing features.

The Entropy Gathering Daemon is a portable perl script which provides a source of randomness on systems that lack an in-kernel /dev/random. GnuPG, OpenSSH, and the OpenSSL toolkit can use EGD to seed their random number generators.

Juggernaut v1000 can crack MD4, MD5, MD6, SHA1, SHA256, SHA384, SHA512, HMAC-MD5, HMAC-SHA1 and also all the Base-64 version of them in minutes... but the cracking process depends in your password wordlist/dictionary.

Designed to use what is known about users via the /etc/passwd file on unix/linux systems to generate a dynamic dictionary or csv file of more accurate guesses as to what their possible password may be, to look for bad password protection practices.

MD5-utils is a script for MD5 hash function manipulations. It can crypt one or more word(s) and try to crack one or more hash(es) using online servers.

Released under 'Creative Commons v3' license Alien Cipher is an endeavour to build my own symmetric cipher. The primary aim is to simply learn the fundamentals and finer details of cryptography in general and build working examples of my ideas in code. The code is shared here for posterity (future folk) in the guise that it may help others also on the path to cryptography. This code demo uses a 256bit rolling hash table (8x8bytes) at its heart to mix together pre-defined parameters in a way that allows the cipher to produce encoded output that is locked to a key of arbitrary length without padding. Based upon some random data points the cipher produces encoded output that is non-deterministic in nature, the same key and message will never produce the same output each time it's run. The cipher attempts to render output that is resistant to several types of analysis although this has yet to be proven. Please note that I make no claims to this being safe. Cheers o7

Alist is a program that collects hardware and software information about systems and stores it in a database for users to browse and search via a Web interface. The program consists of three parts: a client portion that collects the information, a daemon

A library implementing the AES (American Encryption Standard) or Rijndael algorithms, intended to provide a neat packaged solution for other projects to use. Package includes C and Intel Pentium/MMX assembler versions of AES, along with an extensive

BoCrypto encrypts/decrypts files using one-time-pad keys. Mersenne Twist PRNG is utilized for the key stream. Features enc/dec benchmarking as well as 'duress' key generation. OTP encryption is the only unbreakable encryption, if implemented correctly.

This software is a set of tools that hides C source code in txt files. Also the software is able to restore the txt files to C source code again. This work is based on the tool c2txt2c by Leevi Martilla. Csteg needs a book file in txt format to hide C so

Set of perl scripts to analyse and check expiration of user certificates in Microsoft Windows Certification Authority. Output is in HTML with list of expiration state of latest user certificates. Expirated are marked. List can be sent by e-mail.

CommCA - A Community-driven Certificate Authority for distribution of free X.509 digital certificates for personal email and server use.

Cryptix is an international volunteer effort to produce robust, open-source cryptographic software libraries. Cryptix products are free, both for commercial and non-commercial use and are being used by developers all over the world.

DES Cracker is a small perl script that cracks DES encrypted passwords.Currently there is only a brute force implementation where phrases are generated. Later version will have a possibility to use word lists for cracking.

In DeCrypto you will find a collection of scripts for helping decrypt messages. Eventully I am going to put these scripts together into a nice interface.

EnigmaLike is an Enigma-like encoding tool for text files that encodes word-by-word using a dictionary/code book/encryption reel set-up. EnigmaLike is written using PerlTk and has instructions in PDF format. For Linux.

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.

GNet Server - Network compression client/server software. Compresses data over slow networks to save on the cost of bandwidth. Server is developed for Unix and Windows platforms, The client will run on Windows based PCs.

Use of Michael Rabin's Information Dispersal Algorithm to provide secure, dispersed storage in a networked environment. For full download, please get both Math-FastGF2 and Crypt-IDA releases under the files link. See project wiki for more information.

GnuPG::Interface is a Perl module interface to interacting with GnuPG. It implements a rich set of filehandle communications with GnuPG and includes a key object organization structure, with information gathered from GnuPG's with-colons option.

This perl script merges two keepassx databases into one.
