Cryptography Commands

A digital certificate is a form of electronic identification for computers. The

UNIVERGE WL Controller requires digital certificates to authenticate its

communications to UNIVERGE WLMS and WebView, to Web Authentication

clients, and to Extensible Authentication Protocol (EAP) clients for which the

UNIVERGE WL performs all EAP processing. Certificates can be generated on

the UNIVERGE WL or obtained from a certificate authority (CA). Keys

contained within the certificates allow the UNIVERGE WL, its servers, and its

wireless clients to exchange information secured by encryption.

This chapter presents cryptography commands alphabetically. Use the following

table to locate commands in this chapter based on their use.

Note. If the UNIVERGE WL Controller does not already have certificates, The

UNIVERGE WL Control System automatically generates the missing ones the

first time you boot using UNIVERGE WL Control System. You do not need to

install certificates unless you want to replace the ones automatically generated

by UNIVERGE WL Control System. (For more information, see the “Certificates

Automatically Generated by UNIVERGE WL Control System” section in the

“Managing Keys and Certificates” chapter of the Configuration Guide.)

Note. Before installing a new certificate, verify with the show timedate and

show timezone commands that the UNIVERGE WL Controller is set to the

correct date, time, and time zone. Otherwise, certificates might not be installed

correctly.
