Frequently asked questions
Why is MD5 not available?
MD5 is cryptographically broken and isn't part of the browser's Web Crypto API. We offer SHA-256 and stronger, which are secure and recommended.
What is a hash used for?
Hashes produce a fixed fingerprint of data, used for integrity checks, checksums, and storing password representations. The same input always gives the same hash.
Is my text sent to a server?
No, hashing is done entirely in your browser with the Web Crypto API.
