Hash Generator

SHA-1, SHA-256, SHA-384 and SHA-512 checksums for text or files — computed on your device with the browser's Web Crypto API.

Drop a file
or click to browse (any type, any size)

Files never leave your browser. Nothing is uploaded.

Why no MD5? The browser's Web Crypto API doesn't include MD5 (it's cryptographically broken). For integrity and security use SHA-256 or stronger — it's the recommended default here.
