FAQ

Are the results identical to the command line? Yes. The SHA family uses the browser's native WebCrypto and MD5 is implemented locally; all of them were checked against the md5 command line for 'abc', the empty string and a multi-byte UTF-8 string. MD5 is no longer secure - use it for integrity checks only.
