How to use Hash Generator

Generate hexadecimal digests using your browser’s native Web Crypto API. Text is encoded as UTF-8, with line breaks preserved. Files stay on your device.

Details and limits

SHA-1 is legacy and is not recommended for security-sensitive use. Hashing is not encryption. File input is limited to 20 MiB because Web Crypto requires the complete buffer in memory. Text is limited to 1,000,000 characters; HTTPS is required.
