Encrypted Zip files are any easy and convenient method to store sensitive information locally. Today’s zip archiver software such as Winzip use high-grade encryption algorithms such as AES encryption. So, there is no way to crack open them easily and if you ever fail to remember the password you used to encrypt the zip, there is no “Forgot Password” option too. Your only choice is to use any zip password recovery software. We have already written an article on unzipping password protected zip files without password using the Advanced Zip Password Recovery Tool.
Not every software works for all. So I am gonna share with you another popular zip password recovery software and it’s called Passware Kit Pro. This one is used by big companies, forensics, etc. The software is packed with features to enhance the password recovery process. Let’s jump on to that!

- Passware Kit Standard or better
Passware Kit Features
- Hardware Acceleration
Passware Kit claims that their software run up to 400 times faster with GPU hardware acceleration. The software works perfectly with both AMD and nVidia graphics card but Nvidia seems to perform better in the benchmarks shown on their site.
- Distributed Password Recovery
Passware Kit Forensic and Passware Kit Business versions come with a very special feature called distributed password recovery. What it means is that if you have multiple computers available, then you could use all of its computing power to speed up the recovery process. The software will act as a server and distribute the computing work to the connected computers. This will dramatically reduce the time taken for recovering the lost zip file password.
How long will it take?
That depends on the type of attack you perform. Dictionary attacks take only a few seconds. However, most passwords aren’t plain English words. So Brute force attacks are commonly performed and those may take few minutes to days, weeks, months or even years! Thankfully, the Business and Forensic version of Passware Kit comes with distributed password recovery about which I’ve already mentioned.
“Patience is bitter, but its fruit is sweet.” -Aristotle
In our tests, the dictionary attack performed very well by returning the password in just 2 seconds [password-marvelous]. The joined dictionary attack also performed extremely well by taking just 3 seconds to crack the password [password-test123]. Those aren’t the best passwords to try but it gives you a very small glimpse of this beastly software.
