Add a Private Key and Certificate Chain to a PFX

See more PFX/P12 Examples

Demonstrates Pfx.AddPrivateKey, which adds a private key together with its certificate chain to the PFX object.

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 fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

set pfx = CreateObject("Chilkat.Pfx")

'  The file path is relative to the application's current working directory.  An absolute path

'  Load the private key.

If (success = 0) Then
    outFile.WriteLine(privKey.LastErrorText)

'  Load the certificate and build its chain of authority.  The chain must contain at least one
'  certificate; the certificate at index 0 is treated as the leaf.
