Has Your File Been Tampered With?

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.

Why Verifying File Integrity Matters

Download tampering

Malicious actors intercept software downloads and inject malware. The official SHA-256 hash is your only reliable protection.

Disk corruption

Long-term storage degrades. A corrupted backup that passes a checksum is trustworthy; one that fails is not.

Forensic evidence

In legal and forensic contexts, proving a file has not changed since acquisition requires a documented cryptographic hash.
