Xieve

Passware developed Xieve optimization, which dramatically boosts Brute-Force attack speed by skipping password checks of nonsense combinations of characters. With 95% recovery rate for English words, password search speed is over 75,000,000 passwords per minute.
Limitations

Word 2007 and Excel 2007 use an industry-strength AES encryption algorithm that makes password search speed slow: 20-100 passwords per second on an average PC.
Word 97-2003 and Excel 97-2003 use an industry-strength RC4 encryption algorithm that makes instant password calculation impossible. Office Key finds the password by checking millions of passwords per minute. Brute-force attack is the slowest approach and can test all the passwords of up to 7 characters. Xieve attack is much faster and is capable of recovering passwords of up to 9 characters. Dictionary attack is the fastest method - there is no limitation on password length.
Office Key does not work with documents created with restricted permission using the "Information Rights Service for Microsoft Office."
