hi, I have a key which is in hex as "1C19D5ED8D88DC40" and the data in hex as "041164DFFFFE7FF7". I am supposed to do DES encryption to obtain the encrypted value in hex as "B652FF1BA23C279B". i struggled a lot with all possible encrypting methods of DES but couldn't get the exact value. I found it in this link http://mavroudisv.eu/des/index.php[^] I passed the binary values of the above hex as input and got the desired. Help with C# code to get the above value.

Post the code you've tried. I can't see what you've done from here.

Have tried that already but couldn't get what i expect.

Well it's impossible to guess why you think that encryption will provide the value you are looking for.

Actually i have a tool developed in c++ producing the value which i need. But i need to implement it in c#.

Richard MacCutchan 29-Oct-13 12:05pm

Then you need to see what is different between the C++ implementation and the C# version.

unfortunately, i dont have those codings. I have only the exe.
