What are SSL or digital certificates?

SSL or digital certificates are basically small pieces of code created by using sophisticated mathematics that ensures that communication between devices or websites are sent in an encrypted manner, and are therefore secure.

They play an essential role in keeping IT infrastructure up and running safely and are issued by certificate authorities, who electronically verify that the certificates are genuine.

When issued, these certificates are given an expiration date of anything between a few months and several years.
