<?xml version="1.0" encoding="UTF-8" ?> <class name="Crypto" inherits="Reference" version="4.0"> <brief_description> Access to advanced cryptographic functionalities. </brief_description> <description> The Crypto class allows you to access some more advanced cryptographic functionalities in Godot. For now, this includes generating cryptographically secure random bytes, and RSA keys and self-signed X509 certificates generation. More functionalities are planned for future releases.
