Gaurav's DES Page

So you finally stumbled on here... proves you really have nowhere better to go on the Internet. Anyhow, now that you are reading this, here is some stuff about the project that I am developing (the reason I setup this webpage):

64-bit DES encryption/decryption program in C++

I know that 64-bit encryption is outdated but its easy to implement and understand. Project information, source code etc:

 To read the formal documentation of DES visit:

FIPS 46-2 - (DES) Data Encryption Standard <accessed 29 January, 2003>

The best guide that I could find on the net and the one I used in developing the program is 'The DES Algorithm Illustrated. by J. Orlin Grabbe':

The DES Algorithm Illustrated <accessed 29 January, 2003>

Please help me out in improving the program by downloading the source code (available under GNU license) and working on it.
