Define certificate creation facilities

What is the problem this feature will solve?

Right now, there is a gap in the crypto package in that, while one can parse existing certificates (e.g., new X509Certificate(...)), there's no exposed built-in functionality (that I could find) to create new certificates with specified properties.

This feature will close that gap.

What is the feature you are proposing to solve the problem?

Add new classes and/or methods to node:crypto, so that one can create a signed certificate from its various parts, along with a signing key, CSR, etc.

What alternatives have you considered?

I am currently using the npm package pem for this, which is a thin wrapper around call-outs to the openssl binary (which it assumes is available in the environment).

The npm packagenode-forge seems to have the right functionality and is JS-native, though it is unclear how well-maintained it is.

Beginne mit der Überprüfung der vorhandenen node:crypto X509Certificate-Funktionalität und der in diesem Issue beschriebenen Anforderungen an die Zertifikatserstellung. Definiere die benötigte API zum Erstellen signierter Zertifikate und CSRs aus Zertifikatsteilen und einem Signaturschlüssel, wobei die exponierten Klassen oder Methoden als Abschlusskriterien dienen.
