*** DLL Memory Management ***Because it's possible for the Crypto++ DLL to delete objects allocated
by the calling application, they must use the same C++ memory heap. Three
methods are provided to achieve this.
1. The calling application can tell Crypto++ what heap to use. This method
is required when the calling application uses a non-standard heap.
2. Crypto++ can tell the calling application what heap to use. This method
is required when the calling application uses a statically linked C++ Run
Time Library. (Method 1 does not work in this case because the Crypto++ DLL
is initialized before the calling application's heap is initialized.)
3. Crypto++ can automatically use the heap provided by the calling application's
dynamically linked C++ Run Time Library. The calling application must
make sure that the dynamically linked C++ Run Time Library is initialized
before Crypto++ is loaded. (At this time it is not clear if it is possible
to control the order in which DLLs are initialized on Windows 9x machines,
so it might be best to avoid using this method.)When Crypto++ attaches to a new process, it searches all modules loaded
into the process space for exported functions "GetNewAndDeleteForCryptoPP"
and "SetNewAndDeleteFromCryptoPP". If one of these functions is found,
Crypto++ uses methods 1 or 2, respectively, by calling the function.
Otherwise, method 3 is used.
This all leads me to believe this is at the root of the issues I'm encountering. I've tried adding the following code to my application
#include "stdafx.h"
#include <dll.h>
#include <malloc.h>
using namespace CryptoPP;
#ifdef CRYPTOPP_IMPORTS
static bool cryptoppDllInitialized = false;
extern "C" __declspec(dllexport) void __cdecl GetNewAndDeleteForCryptoPP(PNew &newFcn, PDelete &deleteFcn) {
#if 0
newFcn = &operator new;
deleteFcn = &operator delete;
#else
newFcn = malloc;
deleteFcn = free;
#endif
}
#endif
bool isFipsInitialized () {
return cryptoppDllInitialized;
}
bool initializeFipsLibrary () {
// Make sure the connections to the FIPS DLL are loaded and ready
if (!cryptoppDllInitialized) {
if (!FIPS_140_2_ComplianceEnabled()) {
AfxMessageBox ("FIPS 140-2 compliance was turned off at compile time.", MB_ICONERROR);
return false;
}
// check self test status
PowerUpSelfTestStatus puts = GetPowerUpSelfTestStatus();
if (puts != POWER_UP_SELF_TEST_PASSED) {
AfxMessageBox ("Automatic power-up self test failed.", MB_ICONERROR);
return false;
}
cryptoppDllInitialized = true;
}
return true;
}
#endif
Thanks in advance.
