Frequently asked questions

Can I verify a download's checksum?

Yes — pick the file, then compare the SHA-256 value with the one published by the software vendor. If they match, the file wasn't altered.

Why isn't MD5 included?

MD5 isn't available in the browser's Web Crypto API and is considered broken for security purposes. SHA-256 is the modern default.

Can a hash be reversed?

No. Cryptographic hashes are one-way functions — you can only check whether an input produces the same hash.
