    //  LoadFromFile will load virtually any certificate format file.
    //  It will auto-recognize the format and load appropiately.
    //  A base64-encoded DER X.509 certificate file
    //  contains the binary DER in base64 encoded form.
    //  Therefore, it is a text file that will begin like this:
    //  -----BEGIN CERTIFICATE-----
