Frequently asked questions

Which hash algorithms are supported?

SHA-1, SHA-256, SHA-384 and SHA-512, computed with the browser Web Crypto API.

Can I reverse a hash back to the original text?

No. Cryptographic hashes are one-way, so the original input cannot be recovered from the hash.

Is SHA-1 still safe to use?

SHA-1 is deprecated for security purposes. Use SHA-256 or stronger for anything security-related.

Is my input uploaded?

No. Hashing happens locally in your browser.
