Proteus library is a licensing system for Embarcadero Delphi programmers. Proteus helps you "sell" your program to your customers. With Proteus library you can create demo/trial versions of your application that are time-limited or feature-limited.

 

Typical usage

Deliver your application to your customers where it will work for a period of time (Trial period) then it will switch to Demo mode where program's functionality is severely crippled, or a "nag" screen is shown to encourage the customer to purchase a license.

Once the customers pays you email the Unlock Key to him. The customer enters the key and the program switches back from Trial/Demo to Fully-Functional mode.

 Software Access

Temporary/permanent license:

Limited/total access to your software modules:

Based on which license the customer purchased you will send him a unlock key that unlocks

 

One ring to rule them all
Proteus is really easy to use: you only have to write a single one line of code in order to integrate Proteus in your application:

 

procedure TMyForm.FormCreate(Sender: TObject);
begin
 Proteus.Initialize;
end;

 

Countermeasures

If the keys are leaked by your customers on serial/cracking web sites you can immediately take measure by invalidating the leaked keys. Also, Proteus has measures put in place to make sure the customer does not try to temper with the Trial period or with the license key he has received.
