PKI Tutorial Video

This PKI Tutorial Video provides a description of the elements required to create a secure Public Key Infrastructure (PKI) to issue, manage and revoke certificates.

It provides an overview of a Certificate Authority and how it digitally signs certificates.  It continues with how resources use hashing and the Certificate Authority’s public-private key pair to ensure certificates are valid.

It concludes with a discussion of revocation checking via a Certificate Revocation List (CRL) or an Online Certificate Status Protocol (OCSP) responder.
