Privacy

Everything you send is visible to everyone who opens this page, including the sender IP address. Do not send confidential data, credentials or personal data.

This also applies to DTLS and TLS: the server decrypts your messages and shows their content. Your keys are never shown; the Keys page only lists the identity and a short fingerprint of each key.
