Summary0003951: fcrackzip isn't finding any passwords
Description

I made a password protected .zip file, with passwords like ninja, ninj4, abcd, aa, a and it can't find a password. I used the command:
fcrackzip -b -c aA1 -l 1-5 -v -u '/root/Desktop/test.zip'
I tried it without -u, and -v, but there's really no difference.
I also tried a password attack using rockyou.txt and a custom wordlist, with like 10 words and 1 of them being the right password and it still couldn't find it. I used:
fcrackzip -u -D -p '/root/Desktop/rockyou.txt' '/root/Desktop/test.zip'
any help?

Steps To Reproduce

I'm just creating a folder with a simple text file and compressing it to .zip and adding a password

Could you attach the zip file with the password? Exactly how was the zip file created, 7z, zip, winrar?

It does seem to work attached the example to this:

21:02:root:Kali: # fcrackzip -D -p 'x' -u test.zip

PASSWORD FOUND!!!!: pw == test

21:03:root:Kali: # fcrackzip -b -l4-4 -v -u test.zip

found file 'test.txt', (size cp/uc 19/ 5, flags 9, chk a8c8)
checking pw rUt~
PASSWORD FOUND!!!!: pw == test

21:05:root:Kali: # fcrackzip --version

fcrackzip version 1.0

test.zip (185 bytes)

Due to the age of the OS (Kali Moto [v1], Kali Safi [v2], Kali Rolling 2016.x/2017.1), these legacy versions are no longer supported.
