What type of Application is it? (In what language is it written)

If it's compiled you could put it into the application directly, or encrypt the configuration file and put the decryption key into the application itself.

the application is written in .NET, it use a xml configuration file with differents parameters (connection string, login, password ...)

If this is an ordinary "windows form" application, then take a look at this article:

Simple encryption works well when you're using the "low level" ADO.Net components...  however, if you're using any of the wizard-based features (such as TableAdapters or Entity Framework), then you'll have trouble.   This issues is discussed in the article...
