Been trying to unlock a rar file. rarcrack crashes about 15-20 mins after starting. (I figured out today that the rar file has been corrupted so part of this problem is about a bad rar file. However, it would be nice if rarcrack would exit gracefully??)

I moved rarcrack to /usr/local/bin and set as 755 with root and wheel as user and group respectively.

Hope the following helps make it better. BTW, thanks for fixing up to run on OSX!!

According to brew i have libxml12 installed. Wat?

Can't figure this out. reinstalled brew, etc. several times.

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

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

Never mind, user error. Thanks for the port.

My zip file password is a web address which is specified with www. & .com

Is there any way I can add this pattern to the crack in its xml file? How could I do it?

Thanks!

how to compile this on win10 x64 ？ thanks ！^_^

this is everything I got below my make command.
I should note that I can run the program after this, but erroring upon make is still likely an undesired thing

Hi,
Is it possible to implement the wordlist as an input to the rarcrack? like from Kali /usr/share/wordlists/fasttrack.txt and so on.
Currently it appears only to be a bruteforce, which is ineffective with well known passwords.
Thanks

as i understand, it compares the whole string and not just the start, so there should be the whole string posted above.

There should be some issues to fix.
