Common questions

Is the hash generator free and private?

Yes. Hashes are made in your browser with the Web Crypto API, so text and files are never uploaded.

How do I check if a file download is genuine?

Hash the file here, then compare it with the checksum the publisher lists. If they match, the file was not changed.

Is MD5 safe?

MD5 and SHA-1 are fine for checking files against accidental damage, but not for security. Use SHA-256 or SHA-512 for anything that matters.

Can a hash be reversed?

No. A hash is one-way. The same input always gives the same hash, but you cannot get the input back from it.
