Softpedia Editor's Review for Ultimate ZIP Cracker
|
Restore lost ZIP, ARJ, Word and Excel password
Written by Bogdan Popa on February 15th, 2012
Ultimate ZIP Cracker is an easy to use software solution designed to help you recover lost passwords for multiple file types, including Microsoft Word and Excel documents, ZIP and ARJ archives.
A very good thing about the application is that it's very easy to use, as the whole password recovery process has been designed as a wizard, so you just need to follow a few steps to get the job done.
First, you need to provide the path to the password-protected file, which can be any of the aforementioned formats. You also need to know that Office 97-2003 and files created by WinZip, WinArj or any other compatible compression tool are supported.
There are multiple methods at your disposal, including brief scan, brute force attack, dictionary search, phonetic attack, date search, free type validator, customized search and plaintext attack. Each option comes with a detailed description right in the main window, so it's easy to pick the one you need.
Depending on the password recovery mode you choose, the application then prompts you to pick some other options, such as the password length and the characters that may be used, including as digits, uppercase, separators and low lines.
The password recovery process takes a while depending on the password length and complexity, with stats provides in real time, including current length, percent done, testing password and, if effective, the found password.
Another thing to be praised is the way Ultimate ZIP Cracker manages hardware resources, having just a moderate impact on system performance while performing a password recovery.
Overall, Ultimate ZIP Cracker is indeed one of the useful password recovery tools on the market and the fact that it's built like a wizard makes it suitable for both beginners and more experienced users.

Ultimate ZIP Cracker description
|
Here are some key features of "Ultimate ZIP Cracker":
Password Wizard:
· This method combines several simple search methods. The Password Wizard is highly recommended when you are using the Ultimate ZIP Cracker for the very first time.
Smart search:
· This method also can be called a 'Human factor' search. For example, if your recall that your password was a pronounceable combination of English letters without numbers then the Smart search can find your password faster.
Dictionary search:
· You can use the dictionary of more than 214,000 words to search for the password. Different case combinations and word mutations are available. Also you can use your own dictionary (this can be any text file).
Date search:
· More than 5,000 date formats are used to generate password strings for a given date range.
Customized search:
· In most cases you remember the way you created the password. Say, your name + some number. Or some garbled word surrounded by two characters - ^pefrume&. Use this information to construct your search template. The template can be saved in a file and loaded back later.
Guaranteed decryption:
· This method guarantees that any encrypted Microsoft Word or Excel 97/2000 document will be decrypted within a reasonable time (about 2 weeks (or less) when running on an average Pentium IV system).
· This method is NOT based on password testing.
· Each password you enter is translated into 5-bytes (40 bits) value called 'key' that is then used to encrypt the document body. The Ultimate ZIP Cracker will test all possible key values to find a valid one.
· The number of keys is very large: 1,099,511,627,776. However the number of possible passwords is much bigger. For instance, the number of character combinations in a 10-characters alpha-digital password is 839,299,365,868,340,224. In addition, the key testing is 3 times faster! The full search time for such a password is about 150 years!
Plaintext attack:
· This method will decrypt your whole encrypted ZIP file if you have another unencrypted ZIP file (called plaintext file) which contains at least one file from the encrypted archive. Click 'Find' to locate the plaintext file automatically. When finished decryption the program will try to decode the password, or, if you wish, will write the decrypted file to the disk.
Limitations:
· The trial version of Ultimate ZIP Cracker will reveal your password free of charge (for up to 5 characters in length). For all passwords greater than 5 characters you will need to purchase the full version. What's New in This Release: [ read full changelog ]
· Support for RAR archives (RAR version 3.x)
