Moscow, Russia (PRWEB) March 7, 2007 -- Elcomsoft, a leader in password recovery, has added support for Miocrosoft Office 2007 passwords to Elcomsoft Distributed Password Recovery. The program offers administrators a comprehensive solution for recovering passwords to documents and files when employees forget their passwords, or when they deliberately add passwords to documents in an effort to sabotage their companies. In addition to supporting Microsoft Office 97/2000/XP/2003 documents, PDF files, PKCS#12 certificates, PGP and LM/NTLM hashes used in Windows NT/2000/XP/2003 logon passwords, PGP Whole Disk Encryption, Microsoft Money and OneNote, Intuit Quicken, Lotus Notes ID files, MD5 hashes, the program can now handle new Microsoft Office 2007 encryption.
Microsoft Office documents security is considerably enhanced in version 2007. The encryption information block is the same as in Office XP/2003, but Office 2007 always uses AES encryption (is the strongest industry-standard algorithm available) with 128 bit key and SHA-1 hashing; besides, new version improves the algorithm of converting passwords into keys: 50000 SHA-1 sequential iterations are being performed now. You would never notice it when opening a file because the whole process requires less than a second. But in a password recovery process, the speed drops significantly: one can test only about 500 passwords per second even on cutting-edge processors such as Intel Core 2 Duo. Thus, one computer can find 4-5 letter passwords only, and so the only way to recover longer passwords to Office 2007 documents is using a cluster. 1000 computers are able to maintain the speed at 500,000 passwords -- comparable to the speed of password recovery on a single computer for older Microsoft Office documents.
