We get asked a lot about self signed certificates vs CA signed certificates — specifically why you can’t just sign your own SSL certificates and avoid working through the certificate authorities (CAs).
What is an SSL Certificate Chain and Why Should I Follow It?
To truly understand SSL certificates and what an SSL certificate chain is, you need at least a rudimentary knowledge of public key infrastructure (PKI). PKI is a system of certificate authorities (CAs), root programs, and digital certificates. PKI is the trust model that undergirds SSL/TLS.
Tomcat SSL: SSL Certificates for Tomcat Servers
Apache Tomcat servers are widely used to host websites and execute Java servlets. They’re application servers, and one of the most popular server-types our customers use. Unfortunately, sometimes Tomcat servers don’t play nicely with SSL — at least, this is the case if you’re not sure what you’re doing. That’s why we’ve written a Tomcat SSL guide that discusses SSL certificates for Tomcat Servers.
How to Set Up Multiple SSL Certificates on One IP
Before a transport layer security (TLS) extension called Server Name Indication (SNI) was published, secure sockets layer (SSL) certificates were limited to organization validation (OV) SSL certificates that secured an IP address. For a website to use SSL, it needed a dedicated IP. Today, that couldn’t be further from the truth.
How Do I find My Comodo SSL Certificate Private Key?

How to Move an SSL Certificate to Another Server
Whether it’s because of a server location change or an upgrade, you may need to transfer settings and data from one server to another.
