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.
