Scenario 3 – AES-256 Streaming Encrypt / Decrypt

This scenario demonstrates a symmetric workflow via the streaming APIs. In streaming mode the service returns a detached JWE (General JSON): the header portion is delivered separately from the raw ciphertext, keeping memory usage constant.

1. Generate an AES-256 key (kty="oct").
2. Stream-encrypt a plaintext file (detached JWE).
3. Stream-decrypt the ciphertext.
4. Validate that the plaintext round-trips.

All artefacts are written under temp_files/.

Implementation notes (Java 21+):

• All filesystem operations use the Path API.
• UTF-8 is explicitly specified to avoid platform defaults.
• Directory creation relies on Files.createDirectories(Path, FileAttribute[]) via ExampleUtil.ensureTempDir(Path).

Thread-safety: this class is stateless and immutable.
