OCSP Checker is a browser extension for Chrome that performs an OCSP request to obtain the revocation status of all used SSL certificates on the currently visited website.

Due to restrictions in the Chrome APIs the OCSP request cannot be performed by the browser itself. Therefore the request is done on a server which provides a simple REST Api to trigger the OCSP Request and retrieve the results. The only information passed to the server is the domain (not the entire URL).

The results of the OCSP request (plus some basic certificate information) is displayed in a popup when clicking the extension's icon in the browser's menu bar. If one of the certificates is revoked the extension displays an error page (or only warning if changed in settings).

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

OCSP Checker requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

OCSP Checker may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
