Encryption settings

The MC5-IP offers a great deal of flexibility in its configuration and this extends
equally to its encryption settings that are used to prevent unauthorised
interception of signals. Due to the variety of situations in which the MC5-IP
might be used and the range of viewer applications that need to view it, a
number of settings are available. The encryption settings to use depend upon
how the potential global users will operate.
Important factors to consider when setting these options might be:

• Do all global user connections and operations require encryption?
• Will some global users be using older VNC viewer versions?

MC5-IP encryption settings

The MC5-IP configuration menu offers three encryption settings:

•

Always on

- This setting will force all viewers to use encryption.

Note:

This setting will preclude any VNC viewer versions that do not support
encryption.

•

Prefer off

- This setting does not enforce encryption unless a viewer

specifically requests it. If a viewer has its ‘Let server choose’ setting, then an
un-encrypted link will be set up.

•

Prefer on

- This setting generally enforces encryption unless an earlier

viewer version is unable to support it, in which case the link will be un-
encrypted. If a viewer has its ‘Let server choose’ setting, then the link will be
encrypted.

Viewer encryption settings

The web browser viewers and VNC viewers (of level 4.0b5S or higher) offer four
encryption settings:

•

Always on

- This setting will ensure that the link is encrypted, regardless of

the MC5-IP encryption setting.

•

Let server choose

- This setting will follow the configuration of the MC5-

IP. If the MC5-IP has ‘Always on’ or ‘Prefer on’ set, then the link will be
encrypted. If the ‘Prefer off’ setting is selected at the MC5-IP, then the link
will not be encrypted.

•

Prefer off

- This setting will configure an un-encrypted link if the MC5-IP

will allow it, otherwise it will be encrypted.

•

Prefer on

- If the MC5-IP allows it, this setting will configure an encrypted

link, otherwise it will be un-encrypted.
