AT YOUR OWN RISK

Information reported by CCADB, collected manually, or from third-party sources might be imprecise. Some root stores contain revoked, previously-included, and explicitly disabled certificates. All of these continue to be logged by CT. Ensure direct verification of the root-stores within the OS/browser of interest. Some root stores might be unavailable for live scanning unless the default security policy of your browser is modified. See browser console for debug output.

Database

SQLite database of logs and roots can be imported and exported. Direct access in the browser console via RootExplorer.db object:

RootExplorer.db.db.exec("SELECT * FROM log");
