Microsoft company does not preclude the possibility of disclosing of the source code for Skype to Russia’s Federal Security Service (FSB). The company notes, that this is just a source code, not an encryption algorithm of the program.
      
       Russian FSB will not be able to listen to individual Skype calls with only the source codes, though the data may help it hack the service, according to the Bloomberg.com. The source code is an instruction set of a software product, while coding algorithms are used to protect data.
      
       Russia’s Federal Security Service has already obtained access to a number of Microsoft's products (source code for Windows 7, Microsoft Office 2010, Microsoft SQL Server and some others).
