`$ rarcrack --type zip t.zip

But when I test test.rar, it works out the password word quickly. But this password doesn't match the real pasaword.

`$ rarcrack --type rar test.rar

Thanks.

Do you have links to test.zip and test.rar?

Using the original rar from the code. The threading seems to miss the password which is "100".

See this(single thread):

What does the flag --threads do?

Jared Burrows · Answer 4 · Sat Oct 29 2016 00:49:05 GMT+0800 (China Standard Time)

@aurovrata number of threads to use when trying to crack the password. Having more CPU allows you to utilize more threads and could give you more power when cracking passwords(for this program atleast).

Aurovrata V. · Answer 5 · Sat Oct 29 2016 00:56:07 GMT+0800 (China Standard Time)

Thanks for the reply, makes sense. Quick other question, is there no way to feed a wordlist to rarcrack?

Jared Burrows · Answer 6 · Sat Oct 29 2016 10:12:18 GMT+0800 (China Standard Time)

@aurovrata As of now, no. I didn't write this, only fixed a few warnings and errors to run on Mac OSX. That would be a good idea though!

Hello… I am not a programmer or developer. I am just a designer.
I really wanna run this on an old RAR file. Can you please explain to me how to run this on a MAC ?
Thanks.
Because stuffs on GitHub, are super hard to use.
I need to run something by Terminal ? ? i don't know…

Jared Burrows · Answer 8 · Thu Oct 05 2017 04:39:13 GMT+0800 (China Standard Time)

@dj-sash
Everything you need is in the readme(https://github.com/jaredsburrows/rarcrack#compile).

make
./rarcrack <file>

You need to make sure you have the correct tools via xcode-select --install.

dj_sash · Answer 9 · Thu Oct 05 2017 19:24:10 GMT+0800 (China Standard Time)

Didn't install Xcode :((

dj_sash · Answer 10 · Thu Oct 05 2017 19:24:58 GMT+0800 (China Standard Time)

Can you please tell me what are the tools that I need?

Jared Burrows · Answer 11 · Thu Oct 05 2017 23:59:55 GMT+0800 (China Standard Time)

You really need to use @google. See: https://developer.apple.com/xcode/downloads/.

Armando Barbosa · Answer 12 · Wed Jan 10 2018 21:16:34 GMT+0800 (China Standard Time)

I have the same problem.
In my case the encrypted files are inside a folder located in the root of rar file.

for exemple.
file.rar
> folder
>> file1.img
>> file2.img
>> file3.img

I have a similar problem with a zip file:

mmn@Deskpro-01:~/Temp$ rarcrack --type zip EuroTruckSimulator2PC.zip
RarCrack! 0.2 by David Zoltan Kedves (kedazo@gmail.com)

INFO: the specified archive type: zip
INFO: cracking EuroTruckSimulator2PC.zip, status file: EuroTruckSimulator2PC.zip.xml
GOOD: password cracked: '0'
GOOD: password cracked: '1'
mmn@Deskpro-01:~/Temp$

Indicates immediately '0' and '1' but these are not the true passwords. What could be happening? Does this program detect special characters (* / - _ and others)?
