Advanced Office Password Breaker is a program to decrypt Word and Excel 97/2000 files that have file open protection set, as well as Word and Excel XP 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 two weeks on single Pentium III/1000 PC (or just four-five days on faster dual-CPU systems). Please note that this program does not work with files created in Word/Excel 95 or older, Word/Excel XP with new CSP protection, and for any password by the one to open. For such files, use Advanced Office XP Password Recovery instead.
