Cisco Cisco Email Security Appliance C160 Mode D'Emploi

You can create one or more encryption profiles if you use a local key service. You 
might want to create different encryption profiles if you want to use different 
levels of security for different groups of email. For example, you might want 
messages containing sensitive material to be sent with high security, but other 
messages to be sent with medium security. In this case, you might create a high 
security encryption profile to associate with the messages containing certain key 
words (such as ‘confidential’), and create another encryption profile for other 
outgoing messages.

You can configure multiple encryption profiles for a hosted key service. If your 
organization has multiple brands, this allows you to reference different logos 
stored on the key server for the PXE envelopes.

You create and save an encryption profile to store the following encryption 
settings:

Key server settings. Specify a key server and information for connecting to 
that key server.

Envelope settings. Specify details about the message envelope, such as the 
level of security, whether to return read receipts, the length of time a message 
is queued for encryption before it times out, the type of encryption algorithm 
to use, and whether to enable a decryption applet to run on the browser.
