SSH Algorithm

The SSH Algorithm window allows the configuration of the desired types of SSH algorithms used for
authentication encryption. There are four categories of algorithms listed and specific algorithms of
each may be enabled or disabled by using their corresponding pull-down menus. All algorithms are
enabled by default. To open the following window, click

Security Management > Secure Shell

(SSH) > SSH Algorithm:

Figure 7- 23. Encryption Algorithm window

The following algorithms may be set:
