Why there's no upload step
Hashes are used to verify file integrity, fingerprint data, and check for tampering. This tool uses the browser's native Web Crypto API (SubtleCrypto), the same secure implementation used by browsers internally, entirely on your device.
Questions
Is my text sent anywhere?+
No. Hashing happens entirely in your browser via the Web Crypto API.
Why isn't MD5 offered?+
MD5 isn't available in the browser's native SubtleCrypto API and is considered cryptographically broken — SHA-256 or higher is recommended instead.
