Demonstrates how to add certificates and private keys to a PEM. Visual Basic 6.0

Dim success As Long

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' The Chilkat PEM class was introduced in v9.5.0.49.  
' It requires the bundle to be unlocked, as shown above.
Dim pem As New ChilkatPem

' Add the private key found in alice.key to this PEM.
' 
Dim privKey As New PrivateKey

success = privKey.LoadAnyFormatFile("qa_data/alice.key","")
If (success <> 1) Then
    Debug.Print privKey.LastErrorText
    Exit Sub
End If

' Add it to the PEM:
success = pem.AddPrivateKey(privKey)

' Add the certificate found in alice.crt to this PEM.
' 
Dim cert As New ChilkatCert

success = cert.LoadFromFile("qa_data/alice.crt")
If (success <> 1) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

' Add it to the PEM:
Dim includeCertChain As Long
includeCertChain = 0
success = pem.AddCert(cert,includeCertChain)

' Write the PEM containing the private key and certificate.
' The private key will be output in PKCS8 encrypted form.
' Certificates are never encrypted.

' This is the password that will be required to open and access the private key
' from the PEM we're about to write..
