CAD Password is advanced and extremely fast password recovery tool for AutoCAD drawing files (*.dwg).
Several configurable attacks can be queued: Dictionary (with several languages included), Brute-force with length and charset selectable and Mixed (combinations of independent parts based on dictionary, brute-force or fixed).
Advanced keyboard layouts-aware recovery technique (on the fly conversion from one keyboard layout to another).
Char replacement option (e.g. S,s with 5 or Z,z with 2, etc.)
Highly optimized code (SSE2, AVX) and GPU (AMD, NVIDIA, Intel) utilization guarantees fastest recovery speed.
Latest Intel HD Graphics integrated GPUs can be used for password recovery acceleration.
For example password recovery speed on Intel Core i3 4130 at 3.40GHz + integrated Intel HD 4400 GPU + AMD Radeon R9 270 = ~25 million passwords per second.
NOTE: The default key length used in *.dwg files encryption is 40-bit long. So for every original password there is a multitude of equivalent passwords and equivalent password can be found within a limited timeframe (from hours on i7 to days on core 2 duo) regardless of the original password length. For default 40-bit encryption with no additional knowledge of the password used you can start the search with 8 chars length with "a...z" + "0...9" charset or 13 chars length with "0...9" charset for the guaranteed result.
NOTE: DWG is the native file format for AutoCAD(r) and a trademark of Autodesk, Inc.
