> You may notice the file name “Certificate Revocation Lists.”
> What it is: CRLSets help block website certificates that are potentially unsafe.
> How it's used by Chrome: Chrome can sense when there’s something wrong with a website’s security certificate. When a site is suspected to be unsafe (for example, one that pretends to be a trusted website and tricks you into sharing sensitive information), Chrome uses CRLSets to react quickly.
