An X509 certificate (e.g. for TLS).
The X509Certificate class represents an X509 certificate. Certificates can be loaded and saved like any other Resource.
They can be used as the server certificate in StreamPeerTLS.accept_stream (along with the proper CryptoKey), and to specify the only certificate that should be accepted when connecting to an TLS server via StreamPeerTLS.connect_to_stream.
Loads a certificate from
path ("*.crt" file).
Saves a certificate to the given
path (should be a "*.crt" file).
