= Introduction =

Advanced Office Password Breaker, or AOPB for short, is a program to decrypt Word and Excel 97/2000 files that have file open protection set, as well as Word and Excel XP/2003 files with default (Office 97/2000 compatible) encryption -- guaranteed, regardless the password length and complexity. This is being done by trying all possible encryption keys (instead of brute-force and dictionary attacks) and takes only about ten days on single Pentium 4 PC (or just three-four days on faster dual-CPU systems).


= Requirements =

- Windows 98, Windows ME, Windows NT 4.0, Windows 2000, Windows XP or Windows Server 2003
- about 800 kilobytes of free space on hard disk

Note: to use Professinal or Enterprise Edition of AOPB on a system with two or more CPUs, you should have Windows NT, Windows 2000, Windows XP or Windows Server 2003.


= Known bugs and limitations =

The program does not work with the following files:

- Microsoft Word/Excel 95 or older;
- Microsoft Word/Excel 97/2000 with French regional settings;
- Microsoft Word/Excel 97/2000/XP with any passwords other than "open" ones;
- Microsoft Word/Excel XP with new CSP protection.

All such files are supported by Advanced Office Password Recovery (AOPPR) which is available at:

On Office 97/2000/XP/2003 files with 'open' password, however, AOPR can run only brute-force and dictionary attacks, but they'll fail is password is long enough and well selected.
