For an EnCase evidence file to successfully pass the verification process, what must be true?

For an EnCase evidence file to successfully pass the verification process, both the CRC values and the MD5 hash value must verify. This requirement ensures the integrity and authenticity of the evidence stored within the file.

The MD5 hash value serves as a unique digital fingerprint for the evidence file, while the CRC (Cyclic Redundancy Check) values provide an additional layer of verification by checking for data corruption. By requiring both types of verification to pass, EnCase implements a more robust method for confirming that the evidence has not been altered or damaged since it was originally collected. This dual verification process is crucial for maintaining the chain of custody and ensuring that the evidence is admissible in a legal context.

The other options do not provide the same level of assurance about the integrity of the evidence. Relying solely on the MD5 hash or CRC checks may leave room for discrepancies in the data that could jeopardize the reliability of the evidence.
