Keys and Certificates

When you are using SSH, SSL/TLS, LDAP/Microsoft Active Directory, or HTTPS, you will need to 
install keys and/or certificates or get server keys in order to make those options work properly. All 
certificates need to be created and all keys need to be generated outside of the IOLAN, with the 
exception of the IOLAN SSH Public keys, which already exist in the IOLAN. SSH keys must be 
generated using the OpenSSH format. 
Certificate Authorities (CAs) such as Verisign, COST, GTE CyberTrust, etc. can issue certificates. Or, 
you can create a RSA or DSA self-signed certificate using a utility such as OpenSSL.
