Elcomsoft Distributed Password Recovery
Elcomsoft Distributed Password Recovery (EDPR) offers administrators a comprehensive solution for recovering passwords to Microsoft Office documents when employees forget or lost their passwords. EDPR lets you coordinate all of the unused computing power of every computer on your LAN or WAN, and use distributed processing to restore the lost password by installing the "agents" onto as many computers on the network as the user desires; each of these agents uses brute force to try to recover the lost password. EDPR restores passwords for Word and Excel documents encrypted with 40 bit keys (Office 97/2000 compatible) as well as more recent documents (Office XP/2003) encrypted with CSP. Office 97/2000 documents can be also decrypted by recovery of encryption keys instead of password, and that type of attack gives a guaranteed result regardless of password length and complexity.
