🔒 Deze tool werkt volledig in je browser. Je bestanden worden nooit naar een server geüpload.
Keys are generated and used entirely in your browser using Web Crypto, and nothing is transmitted or stored. Encryption proves nobody else can read the message; it does not prove who sent it, because anyone with the public key can encrypt to it.
