What is the purpose of the safe_deserialize function when key verification fails?

• A. To verify key equality and prevent tampering
• B. To speed up deserialization
• C. To compress data
• D. To encrypt data

Answer: (A)

The function is about ensuring integrity and authenticity of serialized data. It checks that the key used to verify or decrypt the data matches what is expected. When that verification fails, the correct behavior is to stop the deserialization process and reject the data, preventing any tampering from being exploited. This safeguards against malformed or malicious input being turned into usable objects or executed by the program. Because the goal here is to protect against tampering, not to speed up deserialization, compress data, or encrypt data, the other options don’t fit. Speed, compression, or encryption are separate concerns and don’t address the risk exposed when the key verification fails.
