What is a hash function?

A hash function takes input data and produces a fixed-size string of characters (hash). The same input always produces the same hash, but you cannot reverse a hash back to the original data.

Which hash algorithm should I use?

SHA-256 is recommended for most purposes. SHA-512 offers more security. MD5 and SHA-1 are considered weak for security but are still used for checksums.

Yes. All hash computation happens in your browser using the Web Crypto API. No data is sent to any server.
