The Winja product provides a rudimentary form of security known as encryption.  Data sent from a user's workstation is passed through an algorithm that changes the form of the data from readable text to unreadable text.  When the data is received by the Winja server software it is again passed through an algorithm that changes it back to readable text.  This process is repeated, in reverse,  when data is returned from the server to the user workstation.  This process allows data to be exchanged across the network in a manner that ensures anyone intercepting the data could not easily read the information.
