' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim http As Chilkat.Http
Set http = Chilkat.NewHttp

' Call SetSslCertRequirement to require that the SSL server certificate's domain
' matches only the domain we are intending to communicate with.

' In this example we will test with the URL https://wrong.host.badssl.com/
' which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

http.SetSslCertRequirement "SAN","wrong.host.badssl.com"

' Also validate the server cert..
http.RequireSslCertVerify = True

' Try sending the request.  It should fail within the SSL/TLS handshake
' because the server's certificate does not match the domain "wrong.host.badssl.com"

html = http.QuickGetStr("https://wrong.host.badssl.com/")
If (http.LastMethodSuccess = False) Then
    Debug.Print http.LastErrorText
Else
    Debug.Print "Unexpected success."
End If
