   4 Subject: [PATCH] explicit_bzero: Do not call SecureZeroMemory on UWP builds
   5
   6 The call is forbidden:
   7 https://docs.microsoft.com/en-us/previous-versions/windows/desktop/legacy/aa366877(v=vs.85)
   8
   9 It's considered a legacy API and is implemented as an always inline function.
  10
  11 There is no good replacement API that is available in UWP.
