Loads a Java keystore file and saves the trusted certificate entries to a PEM file.

'  See Global Unlock Sample for sample code.

Dim jks As Chilkat.JavaKeyStore
Set jks = Chilkat.NewJavaKeyStore

Dim jksPassword As String
jksPassword = "myJksPassword"

'  Load the Java keystore from a file.  The JKS file password is used
'  to verify the keyed digest that is found at the very end of the keystore.
'  It verifies that the keystore has not been modified.

If (success <> True) Then
    Debug.Print jks.LastErrorText
    Exit Sub

'  Open/create the output PEM file.
'  This example uses Chilkat's file access class for writing the output file.
'  You may replace the file I/O lines of code with whatever is most convenient for you.

'  and append it to the output file.
