1.0 Important Information about Certified and Self-Signed Certificates

An SSL connection with a self-signed certificate creates an encrypted connection between the server and web browser to assure the information flowing in between can’t be intercepted or interpreted by a 3rd party. A self-signed certificate does not guarantee the server is who they claim to be.

The highest level of security is achieved with a certificate provided from a 3rd party CA (Certification Authority) such as Digicert and GlobalSign. Certificates must be registered to a domain and require the domain owner to submit an application to the CA; however, this process is not covered in this document.
