Need source code for DES Cryptography (Encryption/DeCryption) in C/C++

hi folks;

I have not been able to find a class (even C functions ) on the net .
Does anyone know where i can get copy of this source class / C++ .?

thanks.

AH,

You need source code for DES, I Just so happen to have the source code that you would be needing. The code is in C++. It works fine, but for 3 things. The method i have is triple DES meaning that it is DES encryption run 3 times. My program does not handle the file reading and writing as well as it could.
My program is a very simple implementation, don't get me wrong, it works perfectly, but this is not a user friends application. I could make it a lot more user friendly, but at the moment i'm not motivated.

Great ..
Love to take a look at teh source and make sense of it myself
Please email saeedr43 at yahoo

Thanks alot :thumb: :wave: ;)

It is a VERY BAD IDEA to use home grown encryption algorithms (even experts with decades of experience screw up), use open source libraries instead like OpenSSL.

You may use the source code on my webpage here:

The DES is in C and should compile for windows. The code works very good and I think it's pretty well optimized (I didn't write it...check the headers for info).

well good, I'm glad my work isn't HOME GROWN, I did it at an internship.

But thanks for your faith

PS. Go to my site for a brief report on the algorithm and a working example. The example was written with MS Visual C++ 6.0 and compiles and runs.
