Getting cert info

[GaryK]

After initiating an SSL connection is there any way to retrive specific
information about the SSL cert being used? On export I noticed
InternetGetCertByURL but this seems to be stubbed out?

Thanks.

Hi Gary

You could use InternetQueryOption passing the
INTERNET_OPTION_SECURITY_CERTIFICATE flag.

I hope this helps you

1) I use this to query our SSL certficate
ret=InternetQueryOption(hReq, INTERNET_OPTION_SECURITY_CERTIFICATE,
NULL, &len);

2) I get this information back properly filled-in
FILETIME ftExpiry;
FILETIME ftStart;
LPTSTR lpszSubjectInfo;
LPTSTR lpszIssuerInfo;
DWORD dwKeySize;

3) This information comes back as NULL
LPTSTR lpszProtocolName;
LPTSTR lpszSignatureAlgName;
LPTSTR lpszEncryptionAlgName;

Question 1) How do I get the information in item (3) above to be filled-in
properly?
Question 2) How do I get other information such as the public key?
