SSL Certificate Checker

Verify SSL certificate validity, expiration dates, issuer information, and security details for any website. SSL certificates are crucial for website security, SEO rankings, and user trust. Ensure your site's certificate is properly configured and up to date. For comprehensive security analysis, also check Core Web Vitals and page speed.

Enter Domain

Input the website domain you want to check (e.g., example.com).

Analyze Certificate

The tool connects to the domain and retrieves SSL certificate information.

Review Results

Get detailed certificate info, validity status, and security recommendations.

Check SSL Certificate

Why SSL Certificates Matter for SEO

SSL certificates encrypt data transmission between your website and visitors, protecting sensitive information. Google considers HTTPS a ranking factor, and modern browsers mark non-HTTPS sites as "not secure."

Regularly check your SSL certificate expiration to avoid browser warnings that can hurt user trust and SEO. Use strong encryption (2048-bit or higher) and keep certificates from reputable Certificate Authorities (CAs).

Assistant: Now, update todo: create_tool_page completed. Next, add routes in main.rs Read main.rs to see how routes are structured. Look for keyword-density-checker route. Search for it. Use grep to find routes. grep "keyword-density-checker" in src/main.rs But since it's Rust, perhaps search for the path. Read main.rs partially. First, list the file. It's src/main.rs, probably large. Use grep. grep "keyword-density-checker" src/main.rs But since I can't, use the tool. Use grep tool. Pattern: keyword-density-checker Path: src/ Include: *.rs Yes. Also, to see the structure, read parts of main.rs. First, grep. The tool is grep, pattern "keyword-density-checker", path "src" Yes. Then, read around those lines. Also, see how the handler is implemented. Probably there's a function for it. For SSL checker, I need to implement similar. But since it's server-side, I need to write Rust code to check SSL cert. Probably using rustls or reqwest with tls features. But to keep it simple, perhaps use a library. First, find how keyword-density-checker is implemented. grep "keyword_density_checker" or something. Let's do the grep. Pattern: keyword-density-checker Path: src Include: *.rs Yes. Then, read the function. Also, see the route. Probably in main.rs, there's a route like .route("/tools/keyword-density-checker", ...) Yes. For SSL, similar. But I need to implement the logic. First, add the route. Then, implement the handler. For the handler, I need to check SSL cert of a domain. In Rust, I can use reqwest with rustls, but to get cert info, perhaps use openssl or native-tls. But to keep it simple, perhaps use a crate like 'rustls' or 'webpki' to parse cert. But perhaps easier to use 'reqwest' to make a request and get the cert from the response. Reqwest can give peer certificates. Yes, reqwest::Response has extensions, but for cert, need to use Client with tls_info feature or something. Actually, reqwest has a way to get certificate info. But perhaps use 'tls' feature and get from the connection. To make it work, I can use the 'openssl' crate if available, but check Cargo.toml Read Cargo.toml to see dependencies. Use read on Cargo.toml. Then, see if openssl is there. If not, add it. But since it's a tool, perhaps implement a simple check. For now, let's add the route first. Find where routes are added. grep "route" src/main.rs | head -20 or something. Use grep "route" src/main.rs But since tool returns matches. Let's do it. First, grep for "keyword-density-checker" to find the route. Yes. Then, read around that line. Also, see the handler function. Probably there's a mod or something. Let's start. Use grep. Pattern: keyword-density-checker Path: src Include: *.rs Yes. Then, based on that, read the file around those lines. Also, to see the handler, grep for the function name. Probably fn keyword_density_checker or something. Let's see. First, call the tool. The grep tool. pattern: keyword-density-checker path: src include: *.rs Yes. Then, it will give file paths with matches. Then, read those sections. Yes. Also, for SSL, I need to implement similar. But for SSL check, I need to add dependency if needed. First, check Cargo.toml for existing deps. Read Cargo.toml. Yes. Let's do multiple calls. First, read Cargo.toml. Then, grep for keyword-density-checker in src/*.rs Then, read the relevant parts. Yes. Use concurrent tools. Yes, the system allows multiple tool calls in one response. So, I can do that. Let's do: 1. read Cargo.toml 2. grep pattern="keyword-density-checker" path="src" include="*.rs" 3. Then, based on that, read the main.rs around the lines. But since grep gives lines, I can read offset around. Yes. Also, to see the handler, grep for the handler name. But first, let's see what grep returns. Assume it returns src/main.rs: some line Then, read filePath="src/main.rs" offset= line-10 limit=50 or something. Yes. Also, for the handler, probably there's a separate function. Let's start with the calls. First, read Cargo.toml to see deps. Then, grep. Yes. Also, to implement SSL check, I can use 'reqwest' with 'rustls' feature, and get cert info. But reqwest doesn't directly give cert details, but I can use 'rustls' crate to parse. Perhaps use 'openssl' for simplicity. Check if openssl is in deps. Read Cargo.toml. Yes. Let's call. Also, for the tool, since it's server-side, I need to add the handler. First, add the route. Then, add the handler function. For the handler, I need to take domain, check SSL, return result. To check SSL, I can use reqwest to make a HEAD request or GET, and if it succeeds, the cert is valid, but to get details, need more. To get cert details, I can use the 'tls' feature of reqwest, but it's experimental. Use 'native-tls' or 'rustls' with webpki. Perhaps use the 'x509-parser' crate to parse cert. But to keep it simple, perhaps add openssl as dep. Check if it's there. Read Cargo.toml. Yes. Let's do the tool calls. First, read Cargo.toml. Second, grep for keyword-density-checker in src/*.rs Third, perhaps grep for "fn.*checker" or something to find handlers. But let's start. The response can have multiple tool calls. Yes. So, I'll do: Cargo.toml
