D Correct answer
Explanation

The sign() method creates a digital signature for the provided input data and returns the signature in a string. Digital signatures provide authentication, integrity, and non-repudiation by using cryptographic algorithms to sign data. Unlike encryption (which hides data) or encoding (which transforms representation), signing provides a verifiable signature that proves the data originated from a specific source.
