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. Resolve a pre-provisioned AES-GCM-256 key from the demo-cli playground (the SDK is data-plane-only — it does not create keys).
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 enforced explicitly to avoid platform defaults.
• Directory creation relies on ExampleUtil.ensureTempDir(Path).

Thread-safety: this class is stateless and immutable.

3.0.0

Method Details

main

public static void main(String[] args)

Runs the AES-256 streaming encrypt/decrypt scenario.

Loads CLI properties, authenticates against ANKASecure©, and delegates to the scenario logic. On any unrecoverable error the JVM terminates via ExampleUtil.fatal(String, Throwable).

Parameters:

args - command-line arguments (ignored)
