Strong Encryption Support
Not all Citrix ICA clients support the use of strong encryption to provide secure ICA connectivity to a MetaFrame server running Feature Release 1 or the SecureICA option pack. Table 4 summarizes the available clients and their supported encryption level. I recommend that you periodically check the Citrix Web site for updated information on the status of a specific client and its support for strong encryption.
