Each of these encryption options is better than the once preceding it. DES is the weakest algorithm, but it often used even on newer servers in order to maintain compatibility between older and newer systems. For maximum security, the general consensus is to use Blowfish encryption when possible.

The SuSE configuration next asks that you provide details about your system's network connectivity and to provide information regarding remote management capability.

The two items you do not see listed above are "Proxy" and "VNC Remote Administration".
