CertGetCertificateChain() is the alternative, as you already noted.

Thanks.

Subject: signature verification without WinTrust


Hi,all

I would like to verify signature without using WinTrust.

Does anyone know what functions should be used and
how those functions should be used?

I know WinTrust is prepared for verification of signature. However, it
is described as follows in MSDN document.

----begin
Purpose
WinTrust includes a function and structures used by that function to
verify trust in files, catalogs, memory blobs, signatures, or
certificates. In the case of verifying certificates, WinTrust calls the
CryptoAPI trust chain building functions, CertGetCertificateChain and
CertVerifyCertificateChainPolicy. An application can use those functions
directly, and their direct use is recommended. ----end

Thank you.
