Using SecureZeroMemory in Delphi
c, c++, delphi, memory, security
Solution
As far as I understand, the only difference between `ZeroMemory` and `SecureZeroMemory` is `SecureZeroMemory` is implemented as an inline function, ensuring it won't be optimised out by the compiler.
I don't think Delphi performs the same level of compiler optimisation, so `ZeroMemory` calls shouldn't be optimised out.
Problem
I understand there is a `SecureZeroMemory` function in C. The function implementation is defined in `<WinnNT.h>` as `RtlSecureZeroMemory` function. QNS: How can `SecureZeroMemory` be used in Delphi? Did Delphi release a library that contains that function? I'm using Delphi 7. `Windows.pas` only has `ZeroMemory` but not `SecureZeroMemory`.
