A PKI certificate is used as a way to protect the public keys that are a part of your digital signature or digital certificate. These certificates are used as a way to validate 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 issues your digital certificate and allows you to merge your digital signature with a public key and where necessary a personal identifier such as your real name.
You Need to Verify the Identity of the Company Issuing Your PKI Certificate
One of the most important steps you need to take is to make sure that the certificate authority you are planning to use is a legal provider for the PKI Certificate you are planning to use. You can verify this 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 on revocation list.
