Tool
Hash text
SHA-1, SHA-256, and SHA-512 digests are computed together, locally in your browser.

About the hash generator
Compute SHA-1, SHA-256, and SHA-512 digests of any text using your browser’s built-in Web Crypto API. All three run together, in hexadecimal.
How it works
Your text is encoded as UTF-8 bytes, then hashed with crypto.subtle.digest — the same standard cryptographic primitive used by native apps and servers, run locally instead of on a server.
Choosing an algorithm
SHA-256 is the common general-purpose choice. SHA-1 is weaker and mainly useful for legacy compatibility (e.g. Git object IDs). SHA-512 trades a longer digest for extra margin.
Requirements
Requires a browser with the Web Crypto API (every current version of Chrome, Firefox, Safari, and Edge). Input is limited to 5,000,000 characters.
Privacy first
Hashing runs locally in your browser. Nothing you type is sent to a Dockzio server.
