Comment (by teor):

 Replying to [comment:22 teor]:
 > Win32 also apparently has memset_s.

 Windows has SecureZeroMemory in Windows.h.
 https://msdn.microsoft.com/en-us/library/windows/desktop/aa366877.aspx

 As long as we build with headers that contain SecureZeroMemory, the code
 will work on any Windows version:

 "This function is defined as the RtlSecureZeroMemory function (see
 WinBase.h). The implementation of RtlSecureZeroMemory is provided inline
 and can be used on any version of Windows (see WinNT.h.)"
