Advanced Office Password Recovery (AOPR) is a Windows-based password recovery tool designed to recover, remove, or circumvent passwords protecting documents created with a range of office productivity suites. The tool supports documents from Microsoft Office (versions 2.0 through Office 365), including Word, Excel, Access, Project, Money, PowerPoint, Visio, Publisher, and OneNote. It also handles documents in WordPerfect Office, Lotus SmartSuite, OpenDocument, Apple iWork, and Hangul Office formats. AOPR employs multiple attack methods — brute-force, dictionary, and advanced rule-based attacks — which can be combined into a sequential workflow. For legacy Microsoft Word (.doc) and Excel (.xls) documents protected with 40-bit encryption, the tool targets the encryption key directly rather than the password, enabling recovery within a guaranteed timeframe. This is facilitated by patented Thunder Tables included in the Professional/Forensic edition. GPU acceleration is supported for AMD and NVIDIA video cards, allowing multiple cards to be used simultaneously alongside CPU cores for significantly faster recovery speeds. Heterogeneous computing allows selective assignment of CPU and GPU cores to the recovery task. Certain document types — including those from Lotus SmartSuite and many WordPerfect Office formats — can be unlocked instantly. The tool also incorporates human-factor targeting by allowing users to input known password policy constraints (character types, length, etc.) to narrow the attack scope. Two editions are available: Home ($49) and Forensic ($399). A free trial version is available for Windows.
