In Office 2007 Microsoft has significantly improved the password protection system.

Now the following applications allow to set the file opening password which is used to encrypt a document:

Word, Excel, PowerPoint, Access.

These programs use AES encryption algorithm and the SHA-1 hash is used in password verification. The password verification is now very slow. Only short and simple passwords can be recovered. In Office 2010 there is more complicated encryption algorithm and the password recovery is slower than in Office 2007.

We recommend to use graphic cards (GPUs) to recover Office 2007 and 2010 passwords. Using of modern graphic card significantly increases the password recovery speed.
