Client certificates are digital certificates used to identify individuals when they connect to an SSL server. Public key
lengths of at least 768 bits must be used to be considered secure. The key length is specified in the Certificate Request
used to generate a Digital Certificate.
Client Certificates may be obtained from a Certification Authority (CA) signed with their trusted root certificate, or created
by the Security Server administrator as a Self-Signed Certificate.
Client Certificates obtained from a CA carry a per user charge and must be renewed annually. Self-Signed certificates created
using the Security Server are free.
