Hashing uses the browser's built-in SubtleCrypto API, which implements SHA-512 natively. The hash updates as you type.
The text you enter is never sent to a server. All hashing happens inside your browser tab.
Both are secure. SHA-512 produces a longer hash (128 hex chars vs 64) and can be faster on 64-bit systems. Use SHA-256 unless you have a specific reason to need SHA-512.
No. Hashing uses the browser's built-in SubtleCrypto API and runs entirely on your machine.
