Enumerate Certificates in a PFX

See more PFX/P12 Examples

Demonstrates Pfx.CertAt, which copies the certificate at a zero-based index into a Cert object. The example enumerates all certificates in the PFX.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Dim success As Boolean = False

Dim pfx As ChilkatPfx
pfx.Initialize

'  The file path is relative to the application's current working directory.  An absolute path
'  may also be used.  Supply the path appropriate to your own environment.
'  The PFX password should come from a secure source rather than being hard-coded.
Dim password As String = "myPfxPassword"
success = pfx.LoadPfxFile("qa_data/identity.pfx", password)
If success = False Then
    Log(pfx.LastErrorText)
    Return
End If


'  Enumerate the certificates in the PFX by zero-based index.  Valid indexes are less than NumCerts.
'  The certificate at index 0 is typically the certificate that has a private key, and the remaining
'  certificates are the others in its certificate chain.
Dim numCerts As Int = pfx.NumCerts
Dim cert As ChilkatCert
cert.Initialize("cert")
Dim i As Int
For i = 0 To numCerts - 1
    success = pfx.CertAt(i, cert)
    If success = False Then
        Log(pfx.LastErrorText)
        Return
    End If

    Log("Certificate " & i & ": " & cert.SubjectCN)
