// 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-----
