NEW: Rainbow Tables for password-protected Excel spreadsheets

April 16th, 2009 by Olga Koksharova

And now…. we have Rainbow Tables for Microsoft Excel docs with 40-bit encryption. So, it became possible to reach near-instant recovery of 97% of spreadsheets created in MS Excel 97-2003. Unfortunately, due to specificity of Excel spreadsheets format it’s unreal to get 100%-recovery, still, you can use brute force to cover the rest 3%.

    Advanced Office Password Breaker does not support files with the extension Rainbow Tables. Rt. When he points to the directory of the file, it displays a message that was not Rainbow Tables. What exactly is a program to create a file to be seen Advanced Office Password Breaker.

  3. Iwan,

    We use our own tables (they are shipped with the enterprise version of the software).
