Can handle numbers of any size
This library is a set of classes for handling large numbers . It includes the frameworks to handle numbers in various forms (Integer, Decimal, Fraction, Complex) as well as perform all the basic math functions in any form (addition, subtraction, multiplication, division, modular reduction, exponentiation, shifts...) There are native and managed versions of the classes, as well as classes to take advantage of the library (matrices, crypto, and so on). I have been working on this library as a hobby for quite some time. I started it in order to teach myself programming while chasing my idea that rsa is breakable.
A program to generate random reciprocal bigram tables
A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given. This program was written to supplement the Enigma Simulator by Dirk Rijmenants. http://users.telenet.be/d.rijmenants/en/enigmasim.htm Enigma message procedures: http://users.telenet.be/d.rijmenants/en/enigmaproc.htm

A package of free or open source software for Emergency Purposes
to spread the idea of creating a Emergency Care Package of sorts that can be distributed via hand out or the web.. What I am getting at is the creation of a easy to use software suite that contains information on how to survive disasters or emergency situations in general. The idea would work similar to what Anonymous offers with their "Earthquake in a Box and provide a means to get info out to people and also help defeat censorship

Utility to generate and verify checksums/hashes
CheckMate is a program designed to generate all kinds of checksums and/or hashes. Checksums can simply be displayed or saved and used to verify the integrity of a file later on.
Check some checksum!
A secure and centralized way to get checksums of common downloads. You will find the usual MD5 hash, but also the newer and more secure hashes like SHA-1, SHA-256 and even SHA-512. If the filesize and all up to four hashes match, you should be save to use that downloaded file.

Crybt is a Data-Encryption-Tool. You can use it easily for Dropbox.
Crybt is based on the Rijandael algorithm (AES). You can use it to encrypt your sensitive files direct into your Dropbox. But you can also use it for normal file-encryption. Crybt works with a new algorithm built by me ,that allowes you to save your password almost uncrackable.
Crypt encryption and decryption is based on ASCII Table Shift.
Crypt is the developed based on the ASCII Table shift and it can customized based on the user requirements, right from the shifting order and the level of encryption or decryption. It can be integrated to any of the programming language with the custom build of the source code. It can secure from text file to binary code.
