Your data can be protected with AES encryption by enabling encryption in the ExpeDat or SyncDat clients.  Refer to the documentation for MTPexpedat, DropDat, movedat, or syncdat for details.

Usernames and passwords are always encrypted, even when content encryption is turned off.

Administrators wishing to ensure that data is always encrypted can do so using the server's RequireEncrypt option.  When this is selected, unencrypted transactions will be rejected with an error telling the user that they must enable encryption.

Using encryption will increase the CPU load of both the server and the client computers.  This may cause a slight reduction in performance on very fast networks or very busy CPUs.

Due to U.S. export restrictions, encryption may not be available in some regions.
