excel passwords...

Hi guys,

I've just watched the podcast demonstrating the use of rainbow tables with windows passwords.

Can rainbow tables be used in a similar way to reveal excel 2003 passwords (or any other passwords, apart from windows logins)?

Cheers,

...so what software do I need to generate a hash file from a password protected spreadsheet to use with rainbowtables?

There's plenty of websites offering to recover excel passwords but at a rather high cost for one spreadsheet.

Is it obvious, because I'm having a hard time figuring it out...

Cheers,

cmo

That means the spread sheet is RC4 encypted... and the password is not stored (becasue it is the key for the speadsheet). You may have to resort to a RC4 brute force, I havn't looked paticulaly far yet, but I havn't been able to find a RC4 brte forcer specificly targeted at execl spreadsheets.
