This password can be assigned in Microsoft® Word® and Excel® 97 and later.

 

The file opening password in Word® or Excel® 97/2000 encrypts the document using the RC4 cryptographic algorithm. Microsoft® Office uses the MD5 hash to verify a password. Therefore this password cannot be recovered instantly.

 

AOPR can recover the password using brute-force and dictionary Attacks. For the brute-force attack, specify the password length (up to 15 characters) and password range (may include national symbols). Note that long and complex passwords may require a distributed attack (with Elcomsoft Distributed Password Recovery) to break.
