If you have been told that you should be using a PKI certificate on your web site and have no idea what it is, this may explain it for you. This certificate is used to validate your public cryptographic keys when the time comes for the public keys to be renewed. The PKI certificate is usually issued by the same Certificate Authority that issued you your digital certificate that allows you to merge your digital signature with a public key and where necessary a personal identifier such as your real name to prove you are who you say you are.
You Need to Be Certain You Are Using a Legit PKI Certificate Issuer
One of the most important things you need to know is that it is vital that you make sure that the certificate authority you are planning to go through is a legal provider for the PKI Certificate you are planning to use. You can find this out by looking them up on the PKI Certificate Revocation List before you spend any money. You will find that we are fully authorized to issue PKI certificates and that we have never been placed on the revocation list.
