Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes of text and files
Your files never leave your browser. Nothing is uploaded to any server. Privacy Policy
Generate cryptographic hashes for text and files using the browser's built-in Web Crypto API. Supports SHA-1, SHA-256, SHA-384 and SHA-512 — all run locally with no upload, ideal for verifying download integrity, generating content fingerprints or comparing files.
How to generate a hash
1
Choose source
Switch between Text or File input mode.
2
Enter or upload
Type text or pick a file — all algorithms hash automatically.
3
Copy the hash
Click the copy icon next to the algorithm you need.
All major hashes
SHA-1, SHA-256, SHA-384 and SHA-512 generated with native browser crypto.
Files and text
Hash any text input or upload a file of any size — streamed locally.
Native speed
Uses the Web Crypto API for hardware-accelerated hashing.
Never uploaded
Files and text are processed entirely on your device.
FAQ
MD5 is not part of the Web Crypto API because it's cryptographically broken. Use SHA-256 or SHA-512 instead for new uses.
SHA-256 is the modern default. Use SHA-512 for stronger security. Avoid SHA-1 for new use cases — it's deprecated.
Yes. The tool reads files in chunks using a streaming approach and never uploads them anywhere.
Yes — that's the defining property of cryptographic hashes. Identical input always produces an identical hash.
No. The Web Crypto API runs entirely in your browser. Nothing is sent anywhere.
