CRLite Extension

CRLite – Safer, Smarter Browsing Stay protected from unsafe websites through real-time certificate checks. CRLite automatically verifies every site’s TLS/SSL certificate to detect expired, revoked, or untrusted certificates. If something’s wrong, it blocks the page and explains why — keeping you safe from phishing, MITM, and misconfigured sites. When everything’s fine, you’ll never notice it’s there. KEY FEATURES • Blocks Unsafe Pages Stops sites with expired, revoked (OCSP-checked), or untrusted certificates. • Clear Explanations Displays an easy-to-understand block page showing the domain and reason. • Quick Status Overview The popup shows the last-checked site, status badge, and certificate details (issuer, validity dates, etc.). • Customizable Validation Use the built-in validation service or your own self-hosted one. Toggle revocation checks as you prefer. HOW IT WORKS When you open a webpage, CRLite validates its SSL certificate through a lightweight verification service. It checks: • Certificate expiry • Revocation status (OCSP) • Basic trust validity If an issue is found, CRLite blocks the page and shows the reason. Otherwise, it lets you browse normally. WHY USE CRLite • Prevents certificate-based attacks and phishing attempts • Gives clear, minimal feedback without intrusive alerts • Lets you control your own validation source and settings PRIVACY & PERMISSIONS • No personal data collected • Only the active site’s domain is sent for validation • You can self-host the validation API for complete control • Permissions used: • tabs: to read the active tab’s URL • storage: to save your settings and last result COMPATIBILITY Built for Chrome Manifest V3 Works seamlessly with other privacy and security extensions.
