I need to connect to a WebService and validate my connection using a digital certificate. My clients have two types of certificates: A1 (pfx file) and A3 (token or smartcard).
I was able to use A1 certificates (pfx files), but now I want to know how to ask for an A3 certificate on my application for later use with Indy.
The point is: how to list the Windows' installed/available certificates? With this list, how to use the selected certificate with Indy?
The A3 certificates are selectable through the Windows' certificates stores. Below is a screenshot
Using CAPICOM e WININET I can show this dialog box and "apply" the selected certificate to the connection using InternetSetOptions, and I can also do it using pfx files.
I want to use Indy to have more control about the used protocol (TLS 1.2), because using WININET (Delphi Default for WebServices) the protocol depends on the Internet Options. See below:
