Demonstrates how to add certificates and private keys to a PEM. B4X

Dim success As Boolean = False

'  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 ChilkatPem
pem.Initialize

'  Add the private key found in alice.key to this PEM.
'  
Dim privKey As ChilkatPrivateKey
privKey.Initialize("privKey")

success = privKey.LoadAnyFormatFile("qa_data/alice.key", "")
If success <> True Then
    Log(privKey.LastErrorText)
    Return
End If


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

'  Add the certificate found in alice.crt to this PEM.
'  
Dim cert As ChilkatCert
cert.Initialize("cert")

success = cert.LoadFromFile("qa_data/alice.crt")
If success <> True Then
    Log(cert.LastErrorText)
    Return
End If


'  Add it to the PEM:
Dim includeCertChain As Boolean = False
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..
