  This was a 6-year-old file that was very important to me and I want to THANK YOU for how quickly and efficiently the password was retrieved. I had tried every password I could remember to no avail.

I am amazed by the fact that you manage to decrypt an office file as fast as you do.

I am so relieved and wish to thank you for doing what the product stated in such a small time. I had written this document over 4 months ago and couldn't remember much about it.

Nine years of critical data on an XLS file released back to me in less than five minutes - simply fantastic!!!

About Decryptum Attack (in Passware Kit, Word Key, Excel Key)

Decryptum attack solves the problem of waiting for a password to be recovered. A free preview of encrypted Word or Excel document is ready in less than a minute, regardless of the password length. This unique feature lets you peek into the document before trying to recover the password or paying for the decryption service.

With this attack, the software connects to, Passware's online decryption service for MS Word and Excel documents, to generate a free preview or decrypt files.

The document never leaves your computer. The software extracts a small part of the document that is required to generate a preview or find the decryption key. The document is decrypted locally.

You are required to purchase Decryptum Credits to decrypt files and remove password protection. The partial preview of the file is free.

Passware Kit Standard, Professional, Enterprise, and Forensic editions already include a free Decryptum PIN for one or more files.
