I have placed a password to open on one of my excel files and I cant remember it. I know there are several cracking/decryption programs available for this but they all cost around 30$ (which is crazy for one file). I recently downloaded backtrack 5 in hopes of finding something suitable to find my password. Does anyone have any clues or ideas on how to recover my password? I know the file has a 40bit rc4 encryption and I have a rough idea of what the password is. Thanks in advance.
