Hi Kerberos!
You may read it here the fastest one DES implementaion. There is a source code.

Do you know an exists BruteForce program? Did you find one like this?
I have a DES coded chipertext: 1234567890ABCDEF
I know the plaintext: FEDCBA0987654321
It's a simple DES, not triple DES!
How it is possible to get the key from the plaintext and chipertext pair?
Can somebody write on a program on this?
