`$ 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

What's wrong with?
I also want to kown that this the method of decide the length of the first crack.
Thanks.

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

[jaredsburrows]

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?

[jaredsburrows]

@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]

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

[jaredsburrows]

@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…

[jaredsburrows]

@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]

Didn't install Xcode :((

[dj-sash]

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

[jaredsburrows]

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

[armandobs14]

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
