HTTPS Checker

WHAT IT DOES

HTTPS Checker checks if the current page is loaded over HTTPS, analyzes the SSL/TLS certificate details (issuer, validity, encryption strength) via the browser's security context, and displays a summary with warnings for insecure or expired certificates. The tool provides immediate visibility into the security of your connection, helping you identify pages that may be vulnerable to man-in-the-middle attacks or data interception.

WHERE IT RUNS

This tool works on any webpage, including HTTP and HTTPS sites. It detects the current protocol and provides security analysis based on available browser security context information. It runs on all websites as designated in its match patterns, making it useful for security audits, browsing protection, and developer testing.

HOW TO USE

After installing the BotGentz extension, the tool automatically checks the HTTPS status of the current page when you load it (configurable in settings). The panel displays a clear status indicator: "Secure (HTTPS)" with a green checkmark, or "Insecure (HTTP)" with a red warning. When certificate details are available, the tool displays protocol information, host details, HSTS status, CSP headers, and port information. Use the settings to toggle certificate details, insecure page highlighting (adds a red banner to insecure pages), security badge display, and auto-check on page load. The panel also includes a "Copy URL" button for quick sharing or reference.

TECHNICAL SECTION — SECURITY CONTEXT ANALYSIS

The tool determines HTTPS status directly from the page's protocol using window.location.protocol. For secure pages, it attempts to gather SSL/TLS-related information through browser security context APIs. While browser APIs do not expose full certificate details for security reasons, the tool provides available context including protocol version, hostname, port, and security-related headers (HSTS, CSP) fetched via fetch HEAD requests. The tool identifies HTTP versus HTTPS connections and provides appropriate warnings for insecure pages, including optional visual highlighting with a red banner across the top of the page. This approach provides practical security information without requiring privileged browser permissions or external services.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position per site. It can snap to the left, right, top, or bottom edges, or float freely. Collapse it to a small status indicator when you need more page visibility, and expand it again with a single click. Resize it vertically or horizontally to see more certificate details. Press Escape to close the panel instantly. All settings (show certificate details, highlight insecure pages, show badge, auto-check) are saved globally and persist across sessions.

PLEASE NOTE

This tool requires the free BotGentz extension. It only reads page protocol information and does not intercept, modify, or block any network traffic. Certificate details available via browser APIs are limited for security reasons; the tool shows what information is accessible without requiring extra permissions. The tool does not verify certificate trust chain or check for known compromised certificates. For comprehensive certificate validation, use your browser's built-in security indicator. Websites change their layouts and security configurations frequently; scripts may need updates, and we work to keep them current but cannot guarantee uninterrupted operation.
