XML : Creating sha256 hashes like the one on this code

Does anyone here know how to create the hashes like one's written in the "AppxBlockMap.xml"? If not, does anyone know how to make it ignore these checks and make the app run in desktop environment?

  [Device_REF]Surface RT 8.1[Device_REF]    [REF]C:\Program Files\WindowsApps[REF]    

I am able to edit the file using the add SID method I asked about previously.

An example:
