A Correct answer
Explanation

The seal() method creates a cryptographic seal that binds data together with an expiration timestamp, ensuring data integrity and freshness. Unlike encoding or hashing which only transform data, sealing provides tamper evidence by cryptographically linking the data to a specific time window. This prevents replay attacks where old captured data could be reused.
