Which hash algorithms are supported?

SHA-1, SHA-256, SHA-384 and SHA-512, computed via your browser's built-in Web Crypto API.

Can I hash a file, not just text?

Yes, drop a file to compute its hash directly, useful for verifying a download matches its published checksum.

Which algorithm should I use?

SHA-256 is the most common general-purpose choice today; SHA-1 is included mainly for compatibility with older systems.

Does Hash Generator upload my files to a server?

No. Hash Generator runs entirely in your browser using on-device processing, your files never leave your device.
