[dushantha12]

Hi,

I need a help. I want to generate a MAC using " C ". I tried with google. But it's not work. If anyone have a code please post it.

Thank you.

What exactly do you mean by "generate" a MAC?
Are we talking about 'MAC' like in Network Device MAC Address?

Hi,

Sorry for that I mean Message Authentication Code.

I would suggest that you take a look at the OpenSSL library:

This is a windows forum, the operating system provides already Crypto API. Of course, if for some reason don't want to use it, thenn OpenSSL is a good choice.
