Description

A passive certificate sensor: every certificate, key and chain your browser meets, inventoried locally. Network lookups are opt-in. CertLens turns your browser into a passive TLS certificate sensor. Every HTTPS connection your browser makes shows it a certificate; CertLens keeps every one, and the public keys, issuers and hosts behind them, in a local inventory, and runs 43 rules over it.
