Frequently Asked Questions
- Which algorithms are supported?
- SHA-256, SHA-512, SHA-1, and SHA-384. These use the browser's native Web Crypto API — no library required.
- Why no MD5?
- MD5 is not available in the Web Crypto API. SHA-256 is the modern equivalent for checksums and is more secure.
- Is my text sent to a server?
- No. Hashing runs entirely in your browser using the Web Crypto API.
- What is a hash used for?
- Verifying file integrity, checksums, password storage verification, and fingerprinting content.
How to Generate SHA-256 and Other Hashes Without Uploading
Generate MD5, SHA-256, SHA-512 hashes in your browser using the Web Crypto API. No data is transmitted — the hash is computed locally in JavaScript.
