Scenario 12 – RSA-2048 → FALCON-1024 Streaming Re-sign (Detached JWS)

This scenario migrates a detached JWS signature from a classical RSA-2048 key to a post-quantum FALCON-1024 key, fully server-side—no payload re-upload:

1. Generate an RSA-2048 key and stream-sign a file.
2. Generate a FALCON-1024 key.
3. Re-sign the existing detached JWS on the server (RSA-2048 → FALCON-1024).
4. Stream-verify the new FALCON signature.

Implementation notes (Java 21+):

• All filesystem work relies on Path.
• UTF-8 encoding is enforced explicitly for deterministic behaviour.
• Temporary artefacts reside under temp_files/.

Thread-safety: the class is stateless and immutable.

2.1.0
