SSL certificate check

There are three main types of SSL certificates: DV (Domain Validation), OV (Organization Validation), and EV (Extended Validation). DV certificates are the most basic type, verifying only domain ownership, making them suitable for small websites and personal blogs. OV certificates require validation of the organization behind the domain, providing more trust and security, making them ideal for business websites and online stores. EV certificates offer the highest level of verification, displaying the company name in the browser’s address bar, which is especially important for banks, financial institutions, and large e-commerce platforms. Additionally, there are Wildcard SSL certificates, which secure a domain and all its subdomains, and Multi-Domain SSL (SAN) certificates, which allow multiple domains to be protected under a single certificate.

There are several ways to obtain an SSL certificate. The first option is to purchase it from an official certification authority (CA), such as Sectigo, DigiCert, or GlobalSign. The second option is to get it through your hosting provider, as many hosting companies offer both free and paid SSL certificates with easy installation. Additionally, there are free SSL certificates like Let's Encrypt, which you can install yourself or through your hosting control panel. To obtain an SSL certificate, you need to choose the type (DV, OV, EV), generate a CSR (Certificate Signing Request), verify domain ownership (or provide documents for OV/EV), and install the certificate on your server. Having an SSL certificate not only secures user data but also improves SEO rankings and increases user trust.

There are several ways to check an SSL certificate. The first method is to open the website in a browser and click on the padlock icon in the address bar. This will show details about the certificate, including the issuer, expiration date, and security level. The second method is using our online service – Quickly analyze SSL configuration, detect potential vulnerabilities, and verify proper installation. You can also check an SSL certificate using the OpenSSL command-line tool. Regularly checking your SSL certificate helps prevent security issues and ensures timely renewal.

If your SSL certificate expires, you need to renew it immediately to avoid security risks and potential trust issues with your website visitors. Follow these steps to renew your SSL certificate: 1. **Check the certificate’s expiration date** – Click the padlock icon in your browser’s address bar or use online tools like SSL Labs to verify its status. 2. **Contact your SSL provider** – Purchase a new certificate or check if you can renew your existing one. 3. **Generate a new CSR (Certificate Signing Request)** if required, and complete the verification process. 4. **Install the new certificate on your server** and ensure that the certificate chain is correctly configured. 5. **Enable automatic renewal** (if possible) to prevent expiration issues in the future. If your SSL certificate has already expired, visitors may see security warnings, which can reduce trust, impact SEO rankings, and potentially lead to lost traffic. To maintain a secure and trustworthy website, always renew your SSL certificate before it expires.
