Thanks Chelliah,

And I have one morequestion, "CryptSignMessage()" function works only under
situation of "one signer".I tried
to Sign by two or more signer certificate,the function failed with internal
error(0x80090020).

like tihis
SigParams.cSigningCert      = 4;
SigParams.rgpSigningCert         = rgpSignerCertArray; // initialize somewhere

Is this specification of SimplifiedCryptographicFunction too? or am I
wrong? If is there anyone who succeeded
with this usage, please respond even if only "I can".

Best Regards.
