This webapp is open source. All the files for the webapp are guaranteed to be served securely by TLS from this GitHub repo, as can be independently verified here, by this CNAME lookup. This webapp uses the Elliptic Curve Integrated Encryption Scheme (ECIES) algorithm with 256-bit security, which has security strength equivalent to 3072-bit RSA. For a full overview of this webapp and its security, see here.

CAUTION: Make sure to use a strong password. If you use a bad password like "password", then someone could guess it and decrypt any messages. Also, when you send your ID, do it through something that you trust not to replace your communications. You are securely protected from eavesdropping, but not communications being outright replaced. See the security overview of the webapp for details.
