(VB.NET) Load Encrypted PEM Containing ECC Private Key and Certs and Examine Contents

Loads an encrypted PEM containing an ECC private key and ECC certificate (and chain), and examines the contents.

Note: This example requires Chilkat v9.5.0.66.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

' Note: This example requires Chilkat v9.5.0.66.

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

' Create a PEM containing a valid EC private key and certificates.
' The password for this encrypted PEM is "secret123"
