commit 5e6932a54efef830fd26f2a1c5580e6080a3ce28

    Update encryption.md
    
    The main change is that there is no need to call ``spp.setPermissions(ap);`` as the access permission object is already set in the constructor of ``StandardProtectionPolicy``.
    
    The other changes are minor enhancements:
    - Added ``ap.setCanExtractContent(false);`` as another example of protection
    - Added a few extra comments
