The Racal Simulator Library is an implementation of a software emulation of the Thales (formerly Zaxus, formerly Racal) RG7000 Host Security Module cryptographic device. (Note: This project is now hosted at Codeplex as ThalesSim).

This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

AESEncryptor is a fast and simple utility to protect your files with the Advanced Encryptation Standard algorithm. It is safer than zip or rar files because a simple force-attack can reveal their password. A force-attack to an AES encriptation could delay millions of years. There are available the source code of the GUI, a CaptionProgressBar and the RijndaelCryptorProvider, the core of the application which can start a encriptation process in a simple code line. New Version released (v2.5): - Add English Language - Some Bug Fixes - Added some options - Added some encriptation parameters IMPORTANT CRITICAL UPDATE (V2.5.0.1)!!!!! Fixes an error occurred with the Auto Delete option activated NEW UPDATE (V2.5.0.2) Fixes an crash when the program start or decrypt a file. Thanks to a SourceForge user for report the error UPDATED RijndaelCryptoProvider with a serious bug fix. Also, has been updated v2.5.0.2 and v2.5.0.1 with this new library

A small encryption / decryption application that we are giving away free of charge. Version 1.0.00 - RSA only at the moment. But later versions will have a plug-in system for adding more algorithms.

In this program you will find tools like : Rawdata tool , file encryption , text encryption , program updater , program protecter , password manager , program settings , defult settings , settings viewer and the last is the file hashing. the file hashing you can use 6 hashing types for the file encryption 1 since i ran out of time for it , and the text encryption has 17 different types 12 encrypt and 5 hashing types. some uses encryption keys and some dont. there are AES , 4DES , RC2 , RC4 , MD5 , SHA1 , SHA2 , SHA3 , SHA4 , XoR , Crypt , HeX , BINARY , Rijndael 256 , Obfuscation String , RSA , BASE64. The password manager anything saved WILL NOT BE ENCRYPTED so it is smart to protect the program from others not using it.
