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

Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.

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
