Hash results

MD5 is computed in JavaScript; SHA hashes use the browser crypto API when available.

HMAC-SHA-256

Uses the optional local-only key.

File SHA-256

Calculated locally from the selected file.

MD5

128-bit digest

SHA-1

160-bit digest

SHA-256

256-bit digest

SHA-512

512-bit digest

All hashes are calculated locally in the browser.
SHA-1, SHA-256, and SHA-512 use Web Crypto when available.
MD5 is included for legacy checksums, but it is not suitable for passwords.
The input is treated as UTF-8 text, so multi-byte characters are handled consistently.
