Load Certificate (.cer) and Private Key (.pvk) generated from makecert

See more Certificates Examples

Demonstrates how to load a certificate (.cer) and private key (.pvk) from the files produced by makecert, such as in the following command:

makecert -sv mycertificate.pvk -n "CN=My Simple Certificate" mycertificate.cer -sky Exchange

Visual Basic 6.0

Dim success As Long
success = 0

' First load the .cer file.
' The certificate file (.cer) contains only the certificate (does not include the private key)
Dim cert As New ChilkatCert
success = cert.LoadFromFile("qa_data/certs_and_keys/makecert/mycertificate.cer")
If (success = 0) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

' Next, load the .pvk file.
' Note: The password "secret" is what you entered when makecert displayed the dialog asking for a password..
Dim privKey As New PrivateKey
success = privKey.LoadPvkFile("qa_data/certs_and_keys/makecert/mycertificate.pvk","secret")
If (success = 0) Then
    Debug.Print privKey.LastErrorText
    Exit Sub
End If

' Finally, associate the private key with the certificate.
success = cert.SetPrivateKey(privKey)
If (success = 0) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

' At this point, the certificate can be used for signing.  For example..
Dim pdf As New ChilkatPdf

' ....
' ....

success = pdf.SetSigningCert(cert)

' ...
' ....

' Some Chilkat classes also provide a method where the cert and private key can be passed separately.
' For example, if SetSigningCert2 is called, then we don't need to explicitly associate the private key with the cert.
success = pdf.SetSigningCert2(cert,privKey)
