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

Dim success As Boolean = False

'  First load the .cer file.
'  The certificate file (.cer) contains only the certificate (does not include the private key)
Dim cert As ChilkatCert
cert.Initialize("cert")
success = cert.LoadFromFile("qa_data/certs_and_keys/makecert/mycertificate.cer")
If success = False Then
    Log(cert.LastErrorText)
    Return
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 ChilkatPrivateKey
privKey.Initialize("privKey")
success = privKey.LoadPvkFile("qa_data/certs_and_keys/makecert/mycertificate.pvk", "secret")
If success = False Then
    Log(privKey.LastErrorText)
    Return
End If


'  Finally, associate the private key with the certificate.
success = cert.SetPrivateKey(privKey)
If success = False Then
    Log(cert.LastErrorText)
    Return
End If


'  At this point, the certificate can be used for signing.  For example..
Dim pdf As ChilkatPdf
pdf.Initialize("pdf")

'  ....
'  ....

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)
