' This example requires 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 Chilkat.Pem

' Load the PEM from a file.
' If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
Dim password As String = "myPassword"
Dim success As Boolean = Await pem.LoadPemFileAsync("../myPemFiles/myPem.pem",password)
If (success <> True) Then
    Debug.WriteLine(pem.LastErrorText)
    Exit Sub
End If


' Note: If the app already has the PEM pre-loaded in a string variable, then load it 
' by calling LoadPem instead.  
Dim pemContent As String = "... the PEM contents ..."
success = Await pem.LoadPemAsync(pemContent,password)
' Check for success as before..

' Convert to a JavaKeyStore object.
' The alias, if a non-empty string, will be applied to the 1st private key or 
' certificate.  All other keys and/or certificates will be assigned an auto-generated
' alias.
Dim alias As String = "anything_I_want_here"

' This is the passord that will be required to access the created JKS.
Dim jksPassword As String = "myJksSecret"
Dim jks As Chilkat.JavaKeyStore = pem.ToJks(alias,jksPassword)
If (pem.LastMethodSuccess = False) Then
    Debug.WriteLine(pem.LastErrorText)
    Exit Sub
End If


' Save the JKS to a file.  The password passed here is used for the keyed hash of the
' entire JKS file.  This may be different (if desired) than the password for individual private keys
' contained within the JKS.  
success = jks.ToFile(jksPassword,"../myJksFiles/myJks.jks")
If (success <> True) Then
    Debug.WriteLine(jks.LastErrorText)
