'  Chilkat supports SSL with all of its Internet components:
'  SMTP, POP3, IMAP, FTP, and HTTP.

'  Each component includes a method named SetSslClientCert
'  which has one argument -- a Chilkat certificate object.
'  You'll need to use a certificate where you have
'  a private key.  There are many ways to instantiate
'  and load a certificate into a Chilkat certificate object.
'  It may be loaded directly from a .pfx (or .p12) file.
'  It may be loaded from a certificate that has already
'  been installed into the local machine's (registry-based)
'  certificate store, or the current-user certificate store.
'  It may be loaded from a pair of PEM or DER encoded files
'  (one file for the ceritifcate, and one for the corresponding
'  private key).  Browse through the examples at
'  example-code.com for various examples (in the Digital
'  Certificates section).

'  This example will load a cert from a .pfx (i.e. p12) file.

'  Create an instance of a certificate store object, load a PFX file,
'  locate the certificate we need, and use it for signing.
'  (a PFX file may contain more than one certificate.)
set certStore = Server.CreateObject("Chilkat.CertStore")
'  The 1st argument is the filename, the 2nd arg is the
'  PFX file's password:
success = certStore.LoadPfxFile("chilkat.pfx","secret")
If (success <> 1) Then
    Response.Write Server.HtmlEncode(certStore.LastErrorText) & "<br>"

End If

Set cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.")
If (cert Is Nothing ) Then
    Response.Write Server.HtmlEncode(certStore.LastErrorText) & "<br>"

End If

'  If a PFX file is known to contain a single certificate,
'  you may load it directly into a Chilkat certificate object.
'  This snippet of source code shows how:
set cert2 = Server.CreateObject("Chilkat.Cert")
'  The 1st argument is the filename, the 2nd arg is the
'  PFX file's password:
success = cert2.LoadPfxFile("chilkat.pfx","secret")
If (success <> 1) Then
    Response.Write Server.HtmlEncode(cert2.LastErrorText) & "<br>"

End If

set http = Server.CreateObject("Chilkat.Http")

'  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial")
If (success <> 1) Then
    Response.Write Server.HtmlEncode(http.LastErrorText) & "<br>"

End If

'  Set your HTTPS client certificate:
http.SetSslClientCert cert

'  Build a HTTPS upload request with the files to be uploaded:
set req = Server.CreateObject("Chilkat.HttpRequest")
req.UseUpload 

'  The URL we'll be posting to is:
'  http://www.yourwebserver123abc.com/ConsumeUpload.aspx
'  Therefore, the path part of the URL is:
req.Path = "/ConsumeUpload.aspx"

'  Note: You'll need to edit this example to upload to your
'  own web server.

'  Add some files to the request:
'  The 1st argument is an arbitrary name.  It's the POST form field name.
'  The 2nd argument is the filename currently existing on
'  the local filesystem.  It may include an absolute or relative
'  path, or no path at all if it's in the current working directory.
success = req.AddFileForUpload("file1","hamlet.xml")
If (success <> 1) Then
    Response.Write Server.HtmlEncode(req.LastErrorText) & "<br>"

End If

success = req.AddFileForUpload("file2","dude.gif")
If (success <> 1) Then
    Response.Write Server.HtmlEncode(req.LastErrorText) & "<br>"

End If

'  Send the HTTPS POST and get the response.  Note: This is a blocking call.
'  The method does not return until the full HTTPS response is received.

domain = "www.yourwebserver123abc.com"
'  The only difference in coding between non-SSL and SSL is
'  the setting of these two arguments to SynchronousRequest:
port = 443
ssl = 1

Set resp = http.SynchronousRequest(domain,port,ssl,req)
If (resp Is Nothing ) Then
    Response.Write Server.HtmlEncode(http.LastErrorText) & "<br>"
Else
    '  Display the HTML source of the page returned.
    Response.Write Server.HtmlEncode(resp.BodyStr) & "<br>"
End If
