Certification Authority
A Certification Authority (CA) issues certificates and guarantees the identity of
each certificate owner. There are commercial certification authorities like
CyberTrust or VeriSign and government certification authorities. The certification
authority uses its private key to sign certificates. Anyone can then use the
certification authority's public key to verify the certificates. You can use the P-
2812HNU-51c to generate certification requests that contain identifying
information and public keys and then send the certification requests to a
certification authority.
