In this article, we will explain about Self Signed Certificate and the steps you need to follow when you see self signed certificate warnings  when connecting to your own VPS or Dedicated server.

What is a Self Signed Certificate?

A self signed SSL certificate is an SSL certificate that does not verify the identity of the server. It works the same as a normal SSL certificate with one major difference. Standard SSL certificates are issued and verified by a trusted Certificate Authority (CA).

Standard Certificates

These certificates are verified by a third party to confirm your server is who it says it is. This will allow visitors to your server or website to successfully connect via an encrypted connection.

Self-Signed Certificates

On the other hand, a self signed certificate is not verified by a third party. Instead, your server issues its own SSL certificate so that it may serve encrypted HTTPS access to visitors.

There is no third party to verify whether or not you are connecting to a trusted server. This causes modern web browsers to show a warning, or SSL connection error when visiting these websites.

Normally SSL certificates not verified by a third party certificate authority are not trusted by your browser by default.
