Guaranteed Recovery (developed by LastBit) Guaranteed Recovery was developed by LastBit Corp. in 1999. The unique feature of Guaranteed Recovery is the ability to recover any documents in an acceptable amount of time no matter how long the password is. LastBit Corp. was the first company to offer the solution for guaranteed recovery of password protected Word and Excel documents. The users of our password recovery tools are insured against failures and money losses. In 2004 we developed an improved technology called Express Recovery that reduced the time required to one minute. Guaranteed Recovery can be used for Word and Excel documents protected with a password to open. Guaranteed Recovery doesn’t work with old versions of Word and Excel (through Office 95) or French versions of them. In this case it is not needed because the password can be recovered instantly. Guaranteed Recovery doesn’t work with documents protected using the Advanced Encryption feature available in Office XP and 2003. You can use Express Recovery to recover Office XP, 2003 documents only if they were saved in the default (Office 97/2000 compatible) encryption mode. If the document was saved in the advanced encryption mode, Guaranteed Recovery will not work. Unfortunately, in this case only traditional recovery methods can be applied such as Dictionary Search or Brute Force Attack. If you’re curious: Guaranteed Recovery is the special sort of Brute Force Attack. Formerly in the USA there were serious legislative limitations on the exporting of strong encryption algorithms. Only encryption algorithms with key length up to 40 bit could be exported freely. That’s why Microsoft limited the strength of the Office encryption to 40 bit. Guaranteed Recovery performs a brute force attack on the internal 40 bit key instead of the original password. The 40 bit key length means that there are only 2^40 (about a trillion) possible combinations. It is possible to test them all in a reasonable amount of time. However this is a very calculation intensive task for a single computer so it is performed in our data center. Guaranteed Recovery Peculiarities The original password remains unknown, instead the document is decrypted and protection is removed. Password recovery is performed using our datacenter, so the Internet connection is required. However your document IS NOT sent over the Internet! We consider privacy issues very seriously and do our best to protect your privacy. Only a small piece (about 50 bytes) of your Word or Excel document will be sent to the server. This piece does NOT contain actual document contents or any other private information. All transferred information is encrypted using a strong encryption algorithm. If you have several password-protected files (even with exactly the same password), you have to process each file individually (because each password-protected Word/Excel document has unique random signature that affects recovery process) .

Yes (in case this method is applicable) Requisites/Limitations None Passwords that can be recovered: Word and Excel password to open Pros Recovery takes an acceptable amount of time regardless of the password length. The method is simple. If the password is too long this is often the only method possible. Cons The password remains unknown; if you have several documents to recover, each of them must be processed individually (even if they are encrypted with the same password), per document recovery fee.
