Hello, Does somebody know whether the "Microsoft Unified Security" package for working with TLS works on win ce the same as on PC? After I succeed establishing a secured session with an authentication process (using InitializeSecurityContext), I try to call the EncryptMessage function and it doesn't work the same as on PC. The output buffer that's encrypted in place is smaller then the original one passed. Is that possible? I really appreciate your help. Best Regards, Mike.
