    ISC - The ISAAC Stream Cipher

    ISC - The ISAAC Stream Cipher

    ISC lets you encrypt & decrypt text and files of any type up to 4GB

    ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key.

    FactHash

    Factorial Hashing Function

    My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's less than the block size. I hold no guarantee of the security of this algorithm, USE AT YOUR OWN RISK. I have had no 3rd party analysis done on the algorithm to date, but research is welcome, and a challenge is even provided in CHALLENGE.txt.

    Fileprivacy

    Fileprivacy

    Fileprivacy easily encrypts your files

    Fileprivacy is a small tool which easily encrypts and decrypts files with common algorithms like AES, Blowfish, Triple DES and RSA. You can either use passwords or keyfiles. Since Fileprivacy is coded in Java it should run on all popular operating systems. #######BETA 2####### Bugfix - Beta 1 stopped working if filename was too short or long - added .exe file ####### NOTE ####### This is an early beta implying there are some issues left. The Keygenerator stops working if you change the algorithm after setting the keylength. It has to be restarted for further use. Because there are no start scripts, yet, you have to start Fileprivacy from console by typing: java -jar Fileprivacy-1.0_<version>.jar ####### ALSO NOTE ####### The author of this software is not responsible for the safety of your data. There is no guarantee that one or more of the implemented algorithms cannot be compromised.
