Need help generating a Certificate Signing Request (CSR) with this server? See our article here.

Before you begin...

• Never share private key files. 

• If you plan on using the same certificate on multiple servers always transfer the private key using a secure method (e-mail is not considered a secure method of transfer).

• Make sure you run the SSL Server Test at the end of the installation process to check your certificate configuration against SSL/TLS Best Practices.

There is a video for this solution.
