Certificate Classes

The types of certificates available can vary between different CAs, but usually at least three different types are available, and they are referred to as classes:

Class 1: A Class 1 certificate is usually used to verify an individual's identity through email. A person who receives a Class 1 certificate can use his public/private key pair to digitally sign e-mail and encrypt message contents.

Class 2: A Class 2 certificate can be used for software signing. A software vendor would register for this type of certificate so that it could digitally sign its software. This provides integrity for the software after it is developed and released, and it allows the receiver of the software to verify from where the software actually came.

Class 3: A Class 3 certificate can be used by a company to set up its own CA, which will allow it to carry out its own identification verification and generate certificates internally.
