Microsoft Security, Compliance, and Identity Fundamentals SC-900 Practice Question
A development team plans to publish a software update for public download. They need to give customers a short value that customers can independently recalculate to confirm the file has not been modified in transit or storage. Which cryptographic technique should the team use to create this verification value?
Rely on Transport Layer Security (TLS) session encryption
Encrypt the file with AES-256 symmetric encryption
Generate a file digest with a hashing algorithm such as SHA-256
A cryptographic hash function such as SHA-256 produces a fixed-length digest that uniquely represents the original file but cannot be reversed to reveal the file contents. Customers can hash the received file and compare the result with the published digest; matching values prove integrity. Symmetric encryption and asymmetric encryption protect confidentiality, not integrity verification alone. TLS secures data in transit during a session but does not supply a standalone value that can later be compared for integrity.
