Description

The preview implementation (not very good) is currently in JEP 470.

The recent https://openjdk.org/jeps/524 need new JEP 524 demo implementation and JEP 470 should be turned into a linking class pointing to JEP 524.

NOTE: This is an ADVANCED task to help with. Be sure you understand the requirements. Check previous contributions with advanced label and ask if you have any questions or doubts before doing work that will not be helpful.

Contributor guide

Research direction
Implement a new demo for JEP 524 in the demos java repository. Study the current JEP 470 implementation and the new JEP 524 specification. Create a new class with examples of PEM encoding for cryptographic objects. Then refactor the JEP 470 demo into a linking class that points to the new JEP 524 demo.
