Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert 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 success As Long
success = 0

Dim pfx As New ChilkatPfx

'  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
password = "myPfxPassword"
success = pfx.LoadPfxFile("qa_data/identity.pfx",password)
If (success = 0) Then
    Debug.Print pfx.LastErrorText
    Exit Sub
End If

'  Find a certificate whose certificate-bag localKeyId attribute matches the given value.  The 2nd
'  argument names the binary representation of the id, such as decimal, base64, or hex.
Dim cert As New ChilkatCert
success = pfx.CertByLocalKeyId("01","hex",cert)
If (success = 0) Then
    Debug.Print pfx.LastErrorText
    Exit Sub
End If

Debug.Print "Found certificate: " & cert.SubjectCN
