Cracking A Password Protected Zip File Using Kali Linux Hacking Tools
We often use zipped files to store large files due to its small size and strong encryption algorithm. The zipping utility also comes with a facility of password protection which maintains the security of the files. However, sometimes it so happens that this feature turns into a nightmare if we forget the password.
Hacking a password protected zip file can be done with many password cracker utilities available online. However, if you are a Kali Linux user, password cracking becomes that much more easy with an open source tool called fcrackzip.
Fcrackzip is a fast password cracker partly written in assembler and available for Kali Linux. It is able to crack password protected zip files with brute force or dictionary based attacks allowing you to unzip files even with most hard passwords.

How to crack a password protected ZIP file in KALI Linux June 22, 2018 admin linux, pc & mobile No Comments This is the first tutorial in a long journey called “Ethical Hacking using KALI LINUX” and in this tutorial I am going to show you guys how to crack a password protected ZIP file in Kali Linux. Appnimi ZIP Password Cracker is a free software program which is designed to search for passwords of protected ZIP files. This program guarantees the most complicated passwords recovery. Appnimi ZIP Password Unlocker searches for the password of the protected ZIP file using Brute Force algorithm.
The –u option, Try to decompress the first file by calling unzip with the guessed password. This weeds out false positives when not enough files have been given.
The –c option lets you select the character set, ‘1’ here means password also be numeric.
The -p option lets you select an initial string to start brute-force attack.
Note – as you can see the ‘aaaaaaaa’, if you will count this is total 8 digits for your password to be in 8 digits
Placebo by howard pittman. Syntax – fcrackzip –u –c <your password character type> -l <password digits range> zip file path
Ex – fcrackzip –u –c 1 –l 4-8 ‘/root/Desktop/Test.zip’
In this example, the Zip file has small (lower case) alphabet digits as a password. Here password is ‘abcdefgh’. If your password has small alphabets characters and length of the password is 8 digits.
Syntax – fcrackzip –u –c <your password character type> –p <total digits> zip file path
Ex – fcrackzip –u –c a –p aaaaaaaa ‘/root/Desktop/Test1.zip’
Here we are using ‘a’ after –c because our password has small (lower case) alphabet. If you have doubt that the password has a upper case alphabet than replace ‘a’ with capital ‘A’. If you think that your password has both upper and lower case than you can write ‘Aa’. Just like this if you doubt your password has lower case (a), Upper case (A), numeric (1). You have to write there ‘Aa1’.
Syntax – fcrackzip –u –D –p <dictionary file path> <zip file path>
Ex – fcrackzip –u –D –p ‘/root/Desktop/dic’ ‘/root/Desktop/Test.zip
So finally we have an all-encompassing command for cracking the password protected file which should look like this >
fcrackzip -b -c ‘aA1!’ -l 1-10 -u file_name.zip
Hahahaha, Be a polite man. Or maybe could you create a new version of this fcrackzip ?

I recently downloaded a piece of software that came in a .ZIP archive, but the .EXE software inside of the archive had a password on it. The website that I would have gotten the password from closed a while ago.
Because the executable is password protected it cannot be extracted.
I'm on Windows 7 Home Premium, and I use
winrar
for my archives.Overview Mortal Kombat: Unchained is a port of Mortal Kombat: Deception for the PSP.

So, I guess my question is is it possible to crack a password for a file within an archive without extracting it?

This is reputed to be the gold standard in archive extractors. Not particularly cheap, but they have a great reputation.Elcomsoft Advanced Archive Password Recovery.
The assumption I'm making here is that it's the archive which has the password. This is based on the fact that you say it cannot be extracted; if it were the .exe which were password protected you could extract it, you just wouldn't be able to act on the .exe. Secondly, programs inside password-protected archives are very common, and password protected .exe's are less so.
