Php – How to use SSL certificate on the web-site

htmlPHPssl

I'm new to SSL, but my php web-site will contain secret information from users. I hear that ssl (https) can establish a solid security level. But, how to use it? How to implement it to my html files?

Any guides, links or information will be great.

Thanks in advance.

SSL has nothing to do with your php or html-pages. It's encryption of communication between (web-)server and client (usually a webbrowser) on the application layer.

The way to set it up depends on the web-server used. To cover the two most popular servers:

SSL-Certificates need to be signed by a trusted authority like Verisign to not produce warning messages on the user side.

SSL Certificate – Displaying Remote SSL Certificate Details Using CLI Tools

You should be able to use OpenSSL for your purpose:

echo | openssl s_client -showcerts -servername gnupg.org -connect gnupg.org:443 2>/dev/null | openssl x509 -inform pem -noout -text

That command connects to the desired website and pipes the certificate in PEM format on to another openssl command that reads and parses the details.

(Note that "redundant" -servername parameter is necessary to make openssl do a request with SNI support.)

SSL Certificate on Load Balancer

Depending on the website(s) behind the load balancer, it sounds like you might need a wildcard cert for *.yourwebsite.com , or something similar if all URLs behind the balancer share a common URL.

You could also generate a cert for one of the specific sites with something like Lets Encrypt.
