		A cryptographic key (RSA or elliptic-curve).
	</brief_description>
	<description>
		The CryptoKey class represents a cryptographic key. Keys can be loaded and saved like any other [Resource].
		They can be used to generate a self-signed [X509Certificate] via [method Crypto.generate_self_signed_certificate] and as private key in [method StreamPeerTLS.accept_stream] along with the appropriate certificate.

		<method name="is_public_only" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this CryptoKey only has the public part, and not the private one.

		<method name="load">
			<return type="int" enum="Error" />
			<param index="0" name="path" type="String" />
			<param index="1" name="public_only" type="bool" default="false" />
			<description>
				Loads a key from [param path]. If [param public_only] is [code]true[/code], only the public key will be loaded.
				[b]Note:[/b] [param path] should be a "*.pub" file if [param public_only] is [code]true[/code], a "*.key" file otherwise.
