There are different options you can use, depending on the type of your application.

 

 

 

 

Command Line Parameter for EXE file (password for EXE file)

The protection can be improved significantly by providing a password as a command line parameter. This option should be used if source code is available. If you do not have a source code, you could use an EXE packer to add the password.

 

•The application only starts, if the password, provided in the command line, is correct
•The password should be at least 30 characters long and should contain numbers, upper and lower case characters e.g.r1nBLCV1rZLZI0YyG7J1BiGNc2cLtZg21pfxm1nv9Jl2f34fs2ajVw31ToTQL1QYt

 

  The password may not contain spaces and the character "

 

When a EXE file is specified as a start file, a new option is visible: Command line parameter for EXE file

 

The Multimedia Player provides the password during runtime when the EXE file is invoked.

 

We recommend splitting the password in different parts and variables of the application to prevent, that a hacker can find out the command line by analyzing the EXE file.

 

Sample

 

A very simple method would be to hide the strings in different program parts and make calculations. You can implement more sophistic code like the one below. This is just to outline an idea.

 

x$=”2”

a$=r1nBLCV1rZLZI0YyG7J1BiGNc2cLtZg+str$((val(x$)+1)*7)pfxm1nv9Jl+x$

c$=f34fs+x$+ajVw31ToTQL1QYt

 

commandparameter$=a$+b$+c$

 

.NET offers a SecureString Class. It represents text that should be kept confidential. The text is encrypted for privacy when being used, and deleted from computer memory when no longer needed. For details see: http://msdn2.microsoft.com/en-us/library/system.security.securestring.aspx

 

 

 

Extract all files

 

This option extracts the EXE file AND all other files in the database to a temporary folder. Import only additional files if they should be protected (e.g. if you use the PowerPoint Viewer you also have to import the PPT files). During runtime, the additional files are not protected.

 

 

Delete all files when EXE is terminated

 

This option deletes all files on the temporary folder after the EXE file is terminated. Only uncheck this option if the main EXE file invokes other EXE files. If the application is one EXE file then always check this option.

 

 

Run EXE unprotected on installation directory

 

This option would extract the EXE file to the folder, where the Multimedia Player is located. You could use this option if you have no source code and the EXE file must be on the same folder like the other files. You could additional use a file encryption tool.
