create the same secret.
This lab executes cryptographic operations in your browser, then reveals the bytes that cross the network and the secrets that never do.
Important: ML-KEM establishes key material. AES-GCM still encrypts the request and response.

No. Browsers do not expose their live TLS secrets. This is a TLS-shaped teaching model executing the same classes of primitives.
Classical operations use Web Crypto. ML-KEM loads as a version-pinned JavaScript module and executes locally in the page.
No. The lab is for education, not for protecting production traffic or generating long-lived keys.
