Check in seconds whether a website already uses post-quantum (hybrid ML-KEM) encryption. Free, no sign-up.
We connect to the website the way a modern browser does and report whether the connection used post-quantum key exchange such as X25519MLKEM768.
The full CipherScope report adds email servers, every tested address, certificate chains and step-by-step fixes. It is free for newsletter subscribers.
Yes: the website negotiated a hybrid post-quantum key exchange, so recorded traffic is protected against future "harvest now, decrypt later" attacks.
Partly: some tested addresses used post-quantum key exchange and others did not.
Not yet: the connection used classical key exchange only. It is secure today, but traffic recorded now could be decrypted by a future quantum computer.
