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

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
password = "myPassword"
success = pem.LoadPemFile("../myPemFiles/myPem.pem",password)
If (success = False) Then
    System.DebugLog(pem.LastErrorText)
    Return
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
pemContent = "... the PEM contents ..."
success = pem.LoadPem(pemContent,password)
// Check for success as before..

// Iterate over the private keys.
