Windows验证来自Open SSL php的签名

Question

I use PHP to sign a string with openssl_sign. So far all ok.

The problem is that I want to verify the signature from Windows. For that I pass the certificate, the message, and it's signature to the windows app. How do I use CryptVerifyDetachedMessageSignature to force using the certificate that the PHP code used?

I tried it, but it returns "asn1 bad tag value met" on the signature created by PHP ...

Thanks...

No luck. I finally resorted to openssl_pkcs7_sign which outputs a S/MIME compatible message, which I can handle in Windows.
