Requests to the server, including usernames, passwords, and file paths, are always protected by AES encryption.
The "Encryption" checkbox in the upper right of the main window enables encryption of the data content being transferred.
When the checkbox is enabled, file data, directory listings, object handler data, and all other transaction contents are encrypted in addition to the request information. When the checkbox is disabled, only the request information (usernames, passwords, paths, meta data, etc.) is encrypted.
Usernames and passwords are always encrypted.
Administrators wishing to ensure that content content is always encrypted can do so using either the server's RequireEncrypt option, or by using DropDat to embed a "Require Encryption" setting into ExpeDat Desktop itself.
Using encryption will increase the CPU load of both the server and the client computers which may cause a reduction in performance. On modern CPUs, about one available CPU core is needed to support each gigabit per second of encrypted throughput.
