Expected value (optional)

Hashing uses your browser's WebCrypto API. The file is read into memory and never sent anywhere.
The expected value field accepts hex, base64, sha256-… (SRI) and sha256sum output. It works out which algorithm matches by itself.
SHA-1 is no longer considered collision-resistant; use it only for compatibility with old systems. MD5 is not offered because WebCrypto does not support it.
