//  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-----
//  MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
//  EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
//  ...
