Hash generator and comparer

SHA-256, SHA-384, SHA-512 and SHA-1 over text or a whole file, computed by your browser's own crypto engine. The file never leaves the tab, which is the point: checking an installer against a vendor's published digest should not mean uploading the installer to a stranger.

Everything you type stays in this tab. Share copies a link, never your inputs, unless the tool says it encodes them in the URL.

Algorithm

Text

Or a file

Read in chunks, so a large ISO will not exhaust memory.

Compare against a published digest

Compared without regard to case or whitespace, byte by byte.

SHA-1 is here because a lot of older advisories still publish it. It is broken for collision resistance and has been since 2017, so use it to match an old record, never to decide that two files are the same.
