Paste the hash you expect (the one the download page gives). It's compared against every algorithm here, so you don't have to eyeball 64 characters.
Everything is computed locally, with no network access. The SHA family uses the browser's WebCrypto; MD5 is implemented in this project. MD5 and SHA-1 are no longer suitable for passwords or signatures, but they remain common for integrity checks (confirming a download isn't corrupted). Checksums defend against transmission damage, not a malicious attacker.
