흔히 이렇게 알고 있다

Plug.Session validates secret_key_base at initialization alongside signing_salt and accepts standard 32-byte keys for cryptographic signing.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• assert Plug.Session.init/1 enforces :signing_salt for cookie storage at initialization but defers :secret_key_base validation until runtime, where omitting it or providing fewer than 64 bytes raises ArgumentError only when fetching or writing cookies
• assert calling get_session/2 before fetch_session/2 raises ArgumentError stating the session is not fetched
• assert read-only session inspection never emits a set-cookie response header, while session mutations register a before_send callback to emit signed cookie headers with HttpOnly and path=/
• assert tampered or forged incoming cookie signatures are silently dropped with an empty session map rather than raising a runtime decoding error
• assert configuring :encryption_salt upgrades session payload handling from base64-encoded signed plaintext to AES-GCM ciphertext
• assert configure_session(conn, drop: true) on an active session emits a set-cookie header with max-age=0 to expire the cookie on the client
