Frequently asked questions
Is any data sent to a server?⌄
No. Encoding and hashing run locally in your browser via the built-in Web Crypto API — the text you enter is never transmitted anywhere.
What are SHA hashes used for?⌄
Hash functions are used to verify file integrity, store passwords (combined with a salt), create digital signatures, and uniquely identify data without storing the data itself.
