Why verify file hashes?
A hash (or checksum) is like a digital fingerprint for a file. If even a single byte of the file is changed, the hash changes completely. Use this tool to:
- Verify that a downloaded file (like an ISO or software installer) is not corrupted.
- Ensure that a file hasn't been tampered with or infected by malware.
- Compare two versions of a file to see if they are identical.
