Hi,
I want to be able to encrypt a CString. Since I am doing some application programming in MFC, I would like to use the CryptEncrypt() function. Can somebody show me how to use this function? The example in MSDN deals with encrpyting a file, but I need to just encrypt a string.
I don't need the encryption to be very complicated, just reasonably secure.

Thanks.

      nIdx = 0;

      while (szTemp[nIdx] != 0)
