I wonder how some tools (Passware for example) claim our their website to "instant decrypt" Office files version <2003 40-bit encryption.
Then I saw their secret - I guess - which is "Decryptum Portable : a set of rainbow tables that allow instant decryption of Word and Excel files up to v.2003 with a Rainbow Tables".
What do you think about that ?
Would it possible to implement this kind of attack in hashcat for old Office hashes ?
Once one have the rainbow tables I guess the attack will be hugely fast ?
Thank you for your advices Smile
I'm not a professional, but I've had a password problem, depending on your operating system,
Some free password cracking tools ,such as ;ophcrack ,Offline NT Password & Registry Editor and CMD , 
You can get more passowrd reset tools on Google .

Does this trick work on Office 2007 and later?

Never install such 3rd party software to crack. With latest office package everything is more secure. Such softwares comes with free offers or trials and after install, they will ask for buy.
