It seems silly to me that someone would give me a zip file but not the password to open it. Izotope o-zone 5 crack keygen. I have all of the data, just not the ability to easily read it. So why send the file at all?
Regardless of the answer, this was a fun opportunity to learn a little about John The Ripper (JTR or just ‘john’). There are two versions of john. The normal release and the community “jumbo” release. So which do you use? It depends on what you want to do. Each has a different set of non-overlapping features, and the docs are not always clear on which does what. For the rest of this post I will specifically guide you through using john on OSX to crack a zip file.
Zip support currently only exists in the jumbo release of john, so thats the best place to start, but right away you might notice that by default john is single threaded. Is there a mac today that isn’t multi-core? Cracking can take a long time, so we’ll want to use as much of the CPU as possible to make it faster. Luckily for me, the jumbo release supports OpenMP which can make parts of the program run in parallel.
Sadly for me, OSX Mavericks does not support OpenMP out of the box.
If only I ran linux, this would be so much easier. Of course many other things would be so much harder, but really Apple?
To build john with OpenMP, I need a modern version of gcc which Apple does not provide. In fact, I’m about to spend the next few hours setting up development environment just so I can build john.
UPDATE: As Mems pointed out below in the comments, you can just grab the jumbo version of john from macports as well (I’m assuming it is also built with openmp support):
> sudo ports install john-jumbo
Or you can compile it yourself and fiddle with more optimizations (which is likely unnecessary):
UPDATE: If you installed john from macports, the tools below should already be in your path. See Mem’s comments below…
Before we can start cracking, we first need to setup an input file for john:

Potentially the fastest way to crack the zip file is to use a dictionary attack. There are a lot of dictionaries/wordlists online, and john can iterate through them and through variations on the words in the list. Skull Security has a nice set to get you started. After you have downloaded one, then you can start running john:
If this doesn’t work, you can try brute forcing the password:
