A cryptographic hash is a file’s fingerprint. If even one byte has changed — whether by corruption, a man-in-the-middle attack, or malware injection — the hash will not match.

Long-term storage degrades. A corrupted backup that passes a checksum is trustworthy; one that fails is not.
In legal and forensic contexts, proving a file has not changed since acquisition requires a documented cryptographic hash.
