What is Cloudflare 15-Year Certificate?
Basic Introduction to Cloudflare 15-Year Certificate
Cloudflare 15-year certificate, fully named Cloudflare Origin CA 15-year certificate, is a self-signed SSL certificate provided by Cloudflare for users. This type of certificate is specifically designed for traffic encryption between website servers and Cloudflare, protecting data security during transmission. Compared to general SSL certificates on the market, the Cloudflare 15-year certificate has a validity period of up to 15 years, significantly reducing the frequency of re-application and deployment after the certificate expires. This is a very convenient and practical choice for website managers pursuing long-term stable operation.
Issuance and Verification of Cloudflare 15-Year Certificate
Cloudflare's 15-year certificates are issued by Cloudflare's own CA (Certificate Authority) and are only used for encrypted connections between website servers and Cloudflare. Users can easily generate a CSR (Certificate Signing Request) and download the certificate through the Cloudflare dashboard. Since these certificates are not issued by a publicly trusted third-party CA, they can only be used for connections between Cloudflare and the origin server and are not suitable for direct use on publicly accessible HTTPS websites. This design is mainly to enhance the security of internal transmission while reducing the management burden.
Application Scenarios and Pros and Cons of Cloudflare 15-Year Certificate
Which Websites or Enterprises is it Suitable For?
Cloudflare 15-year certificate is suitable for all websites that hope to simplify the SSL certificate management process, especially enterprise websites or personal blogs with large traffic that need long-term stable operation. For scenarios where server maintenance is frequently required or there is a multi-server architecture, this long-term certificate can significantly reduce the workload of the IT team. In addition, for webmasters who wish to entrust all security responsibilities to Cloudflare, this is also an ideal choice. As long as the website's front-end traffic passes through Cloudflare, the security of data transmission can be ensured.
Pros and Limitations of Cloudflare 15-Year Certificate
The biggest advantage is undoubtedly the 15-year long validity period, allowing you not to worry about certificate expiration and renewal every year. In addition, Cloudflare provides free application, reducing additional costs. Furthermore, the certificate installation and update process is simple and intuitive, suitable for all types of users. However, the Cloudflare 15-year certificate also has its limitations: this type of certificate can only be used internally by Cloudflare and is not suitable for traffic that is not proxied by Cloudflare. If some of the website's traffic does not go through Cloudflare, other publicly trusted SSL certificates still need to be applied for. In addition, if the Cloudflare service is removed from the website in the future, this certificate will also lose its function.
How to Apply for and Deploy Cloudflare 15-Year Certificate?
Detailed Steps of the Application Process
To apply for a Cloudflare 15-year certificate, first log in to the Cloudflare dashboard, select your website, enter the "SSL/TLS" settings tab, and click the "Origin Server" option. Then, click "Create Certificate," and you can choose a validity period of 15 years or 7 days. It is recommended to choose 15 years, enter your domain name and subdomains, and then Cloudflare will automatically generate a public-private key pair and certificate. You can choose to have Cloudflare generate the private key for you or upload a CSR yourself. After generation, download the certificate and private key files and prepare to deploy them to your server.
Precautions for Deployment to the Server
When installing the Cloudflare 15-year certificate on your origin server, please ensure that the server's SSL settings are correct and only allow connections from Cloudflare's IP range to avoid unauthorized access. After the certificate installation is complete, it is recommended to enable the "Full (Strict)" SSL mode in the Cloudflare dashboard to ensure that the connection between Cloudflare and the server is fully encrypted. In addition, regularly back up the certificate and private key files to avoid service interruption caused by file loss. If there are multiple servers, please deploy the same set of certificates to all hosts to ensure consistency.
