Well, in fact, very naïve, just online posts are all stereotyped, simple to tell you the steps:

1. Generate the private key file PEM.
2, do your own CA sign the private key PEM, the contents of this PEM file changed, in addition to a private key segment, there is a CRT field, the CRT segment (this is called the certificate, there is a public key and digital signature (self-signed, Complete waste). In the CRT, delete the CRT in the PEM and the remaining private key segment exists. PEM, there are two files on the hand.

Now you can put the two files in the specified location according to the requirements of Apache,lighttpd,nginx and other servers.

In the future you access the server, the. CRT is passed to the browser, the browser pops up to ask you trust distrust, you say trust, so the browser trusts the waste digital signature, began to use the public key in the certificate to encrypt a variety of things to the server, the server with. PEM decryption, just such a process.
