Description
Check whether the current page's TLS connection uses post-quantum key exchange. Are We Post-Quantum Yet? shows whether the current page's TLS key exchange includes post-quantum cryptography (PQC), such as ML-KEM, either directly or in a hybrid group with a classical algorithm. Open the extension popup to inspect: - The negotiated key exchange group - The TLS protocol version - The cipher suite - Whether a PQC algorithm was detected in the TLS key exchange - The observed subresource URLs grouped by detected PQC key exchange, classical-only key exchange, or unavailable information The main status describes only the key exchange used by the page's main TLS connection. The resource details classify subresources separately when the browser exposes enough TLS information; resources that cannot be determined are clearly marked as unclassified. A detected result does not claim that the certificate signature, application, server, stored data, or every connection used by the website is protected against quantum computers. All detection is performed locally using security information provided by the browser. The extension processes page URLs, observed resource URLs, and TLS details only to produce the current tab's status and resource report. It does not transmit this information to the developer or any third party, and it does not use telemetry or analytics.
