Hash Generator — SHA-256, SHA-512 & More
Free hash generator. Compute SHA-1, SHA-256, SHA-384, SHA-512 hashes instantly using Web Crypto API.
🔒100% Private — Your files never leave your device. All processing runs locally in your browser.
How It Works
Type or paste text, click Generate Hashes. The tool computes SHA-1, SHA-256, SHA-384, and SHA-512 hashes simultaneously using the Web Crypto API — entirely in your browser.
Hashing is a one-way function: you can generate a hash from any text, but you cannot reverse a hash back to text. This makes hashes useful for verifying file integrity, storing password fingerprints, and creating digital signatures.
