Source code for DES algorithm in c++

Triple Data Encryption Standard (DES) is a type of computerized cryptography where block cipher algorithms are applied three times to each data block. The key size is increased in Triple DES to ensure additional security through encryption capabilities. Each block contains 64 bits of data. Three keys are referred to as bundle keys with 56 bits per key. There are three keying options in data encryption standards:

1. All keys being independent
2. Key 1 and key 2 being independent keys
3. All three keys being identical

Key option #3 is known as triple DES. The triple DES key length contains 168 bits but the key security falls to 112 bits.

Why can you not just use an existing encryption library? It will be much more reliable. If on windows you can use the MS CryptoAPI library to encrypt using the DES.

If you still wish to make your own algorithm I found a page with javascript, perl, and php examples you can use to base your own custom conversion on at http://tero.co.uk/des/code.php

Si vous essayez d'installer Win NT, vous pourriez ne pas avoir de support; pas beaucoup de gens l'utilise et la nouvelle g?n?ration informatique pourrait m?me ne pas savoir comment vous aider ? l'installer, sp?cialement avec des "disquettes".

This is a simple network switch and it doesn't require any drivers. You just connect all the computers & other network devices to it using twisted pair LAN cables and that's it.

The DES-3526 has a lot of features and it would be quite hard to teach you everything through FixYa.

I suggest you start by carefully reading the manual. Everything is very well documented:
ftp://ftp.dlink.com/Switch/des3526/Manual/des3526_Manual_500b27.zip

Then, once you have learned more about it, if you still have problems, feel free to write back and we will help you.

Please replace the cable using a D-link straight - through cable. Connect the port 1 to the server
