Detailed Description

template<class T>
struct Chusov::Memory::secure_allocator< T >

A class template redefining the behavior of the Chusov::Memory::allocator class template so that the deallocation function randomizes the memory before the deallocation.

Template Parameters

T	is a type of an element kept in memory managed by the allocator.

Remarks

Use allocator allocator class to manage memory that does not keep sensitive data. This will help avoiding unnecessary performance overhead introduced by the randomizing.
