What is a hash, and why generate one?
A hash (or checksum) is a short fingerprint of any data. Change a single byte and the hash changes completely. People use them to verify a download wasn't corrupted or tampered with, to compare two files without opening them, and to look a file up in malware databases. SHA-256 is the modern default; MD5 and SHA-1 still appear on older download pages but are no longer considered secure against deliberate collisions.
Want to know if a file is dangerous? Use the file reputation checker — it hashes locally and looks the fingerprint up against antivirus databases, still without uploading the file.
Hashes catch a bad file. Acutis catches a bad network.
Checksums tell you if a file is intact. Acutis Go does the same for your connection — a 60-second check that says plainly whether a problem is your machine, your network, or the internet. No guessing. Free.
