body: I am working on a software project that requires the use of a setup program. The one my company is using is InnoSetup.
  
  
  On their [downloads page](https://jrsoftware.org/isdl.php) towards the bottom, under the section titled **Encryption Module** it says:
  
  
  
  > 
  > "For legal reasons, encryption code is not built into Inno Setup. You must download a separate "encryption module" if you wish to utilize Inno Setup's encryption capabilities..."
  > 
  > 
  > 
  
  
  What legal reasons are they referring to?
  
  
  
title: What legal reasons prevent this software vendor from including encryption in their code?
