Which integrity check is used by EnCase to ensure forensic evidence remains unchanged?

• A. MD5 hash
• B. Copy to three drives
• C. Encrypt files
• D. CRC

Answer: (D)

Integrity verification in digital forensics centers on proving the evidence hasn’t changed since it was collected. A CRC, or cyclic redundancy check, is a fast checksum designed to detect most accidental changes that can occur during storage or transfer. In EnCase workflows, CRCs are used as a quick, lightweight way to verify that the evidence image and related files remain intact before deeper analysis. While cryptographic hashes like MD5 provide stronger protection against tampering, CRCs offer a rapid integrity check that EnCase can rely on for routine verification of data integrity.
