Simplified DES Simulator

Filed under: encryption — Tags: , — edipermadi @ 7:31 am

Yet another stuff about Simplified DES, i’ve coded simple program to simulate Simplified DES. I released this program as freeware. You can redistribute it as much as you want, without altering the program. You can use the program for educational use, personal use, commercial use or whatever you want.

Yeah, i think it much better than scretching on bit mapping your paper. It drives you crazy. I hope this program simplifiy your job or your homework perhaps🙂 .

I’ve verified the program and found no error. If you found something funny, wrong, stupid and unusual, please mail me on edipermadi at gmail dot com.

But, i totally take no care about innacuracy, mistakes, or even damages caused by this program. So please take your own risk and have fun. If you download and use the program, means you are ready to take your own risk.

This is the screenshoot, i made it simple and visually understandable:

How To Use It:
– first, select working mode. Initially it set to encryption
– enter 10 bit key, use only “0” and “1”.
– if you are going to encrypt, enter text into textbox labelled plaintext.
– if you are going to decrypt, enter cipher text into textbox labelled ciphertext.
– Have fun

  7. Learning Spanish Online – Buy effective online course this
    is also a vital step. Many degrees allow you the flexibility
    of allowing you to choose Spanish as a elective if you are in University or College.

    All of these things are boiled down to the fact that photography
    clubs are not merely created just for the sake of having them.

  8. That is why only two or three credit cards including nationwide visa card, Lombard
    credit card and capital one credit card are there which have almost
    zero percent foreign currency transaction fees.
    Interest rates vary from extremely high for people with low
    or no credit rating to as low as 0 percent for those with
    great credit. That helps make it vital for you to shell out off your somme stability since if your account has a substantial harmony, then interest premiums will be larger.
