Volatility is an advanced memory forensics framework. It is a command-line tool used to analyze RAM dumps.

Abstract In the field of Digital Forensics and Incident Response (DFIR), the ability to extract encryption keys from volatile memory is a critical capability. This paper provides a technical analysis of the utility dmp2mkey.exe, a tool designed to parse Microsoft Windows memory dump files (.dmp) to derive Master Keys required for decrypting DPAPI (Data Protection API) protected blobs. This process is essential for investigators needing to access encrypted user data, such as saved browser credentials, Wi-Fi keys, and encrypted files, without the user's login password.

In Windows, the DPAPI key cache resides in structures that often resemble the following C-struct simplification:

typedef struct _DPAPI_MASTER_KEY_CACHE_ENTRY 
    struct _DPAPI_MASTER_KEY_CACHE_ENTRY *Flink;
    struct _DPAPI_MASTER_KEY_CACHE_ENTRY *Blink;
    LUID LogonId;
    GUID MasterKeyGuid;
    PVOID KeyPointer;
    ULONG KeySize;
    // ...
 DPAPI_MASTER_KEY_CACHE_ENTRY;

dmp2mkey traverses these linked lists within the memory dump. Once a valid entry is identified, it extracts the MasterKeyGuid (the ID) and the actual cryptographic key bytes. In Windows, the DPAPI key cache resides in

The extracted keys are formatted and output, often into a file format compatible with other forensic tools like Mimikatz or the Impacket library (specifically dpapi.py).

Dmp2mkey.exe (Dump to Memory Key) is a utility program historically associated with Microsoft Windows debugging and crash analysis tools, particularly from the era of Windows XP, Windows Vista, and Windows 7. Its primary function is to convert a Windows crash dump file (.dmp) into a “memory key” or a more structured format that can be analyzed by other debugging tools, such as the now-deprecated UMDH (User Mode Dump Helper) or early versions of the Windows Driver Kit (WDK).
