The security level Basic is just for backward compatibility. It offers only one key for encryption - the Project Secure Key (PSK).

 

If you start a new project, always use the level Advanced. If offers 3 different keys for encryption:

 

 

Licence Protector  uses 2 standard encryption methods for the licence file and then additionally the Write Key to personalize the encryption. The Read Key is used in the application to open the licence file. Read and Write Key are a pair of keys and belong together.

 

If somebody would steel the Read Key he would not be able to develop a generator which could create your licence files.

 

See chapter Project Keys how to create the keys.
