## What it is
pypykatz is a pure Python implementation of parts of Mimikatz, the well-known Windows credential extraction tool. It parses LSASS process memory (live, minidump, or full memory dumps) and registry hives to extract credentials such as NT/LM hashes, domain cached credentials, and LSA secrets.

## Use cases
- extract credentials from an LSASS minidump
- parse NT and LM hashes from Windows registry hives
- dump passwords from a live Windows LSASS process
- analyze Windows memory dumps for stored credentials
- extract domain cached credentials (DCC/DCC2) from registry
- use mimikatz-like functionality on Linux or macOS
- integrate credential parsing into a Python pentesting tool

## When to choose
- you need Mimikatz-like LSASS/registry credential parsing on a non-Windows platform
- you want a scriptable Python library for credential extraction rather than a Windows binary
- you need to process offline artifacts like minidumps or memory images
- you want to integrate credential parsing into your own tooling

## When to avoid
- you need the full Mimikatz feature set, such as kerberos ticket manipulation or pass-the-hash execution
- you are not authorized to use credential extraction tools - this is offensive security software
- you need a pure Windows-native tool with the latest protocol support
