Frequently asked questions
Which hash should I use?
SHA-256 is a sensible default for checksums and integrity checks. SHA-1 is included for legacy compatibility but is no longer considered secure for signatures.
Is my text sent to a server?
No. Hashing uses the Web Crypto API in your browser, so nothing you type is uploaded.
