About Hash Generator (MD5, SHA-1, SHA-256, SHA-512)
Compute hashes for text input using the Web Crypto API. SHA-1, SHA-256 and SHA-512 use native browser primitives. MD5 is implemented in pure JS (legacy / non-cryptographic checks only).
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local. Free forever for everyone, with a Pro plan for power users who want an ad-free experience and API access.
