friend x said someone impersonates me to send a mail to him. What should we do? I sent the letter I want to send. The content is C. I used my private key 2 to encrypt it. The encrypted content is D.

It is very convenient to use a digital signature in VC 2005, as long as it contains wintrust. h. softpub. H and mscat. h, and add wintrust. LIB; you can call the API directly, but it is troublesome to use vc6. You need to refer to the function and struct Declaration on msdn and define the function pointer for the final call. Because the project uses vc6, there is no way, so I had to pin the pointer to the
