Default vcrypt.net protected by (kind of) captcha

Is there a way to make JDownoader be able to decrypt links on vcrypt that are protected by some kind of captcha?

Take for example this link

**External links are only visible to Support Staff****External links are only visible to Support Staff**

You are asked a random question and only if you put the right answer you can see the links. Of course JDownloader is not able to answer the question but it doesn't give me the chance to input the answer by myself (like it does with other captchas).

Actually I've already seen that this kind of captcha is really stupid, because the question is an image generated by a php script that takes the text as an input (so you can see the question just by opening the source of the page). I was thinking about developing an extension or something like this, but I don't know how to access the source code of JDownloader.

Actually I can't believe in myself. I was able to intercept the call to VCrypt plugin and manage the password thing

Ofc this is very rudimental, with the question asked via command line. I think I can brute force all the answers and put them somewhere, so the plugin can skip automatically this captcha request

Would be amazing putting the compiled version of this plugin inside my local installation of JDownloader... I need to know how to do it

What exactly do you need to know? Have you already modified the existing plugin?

I need to know different things.

I would like to know how to make a kind of pull request, but first I need to know all the classes that I may need (e.g. Browser for example).

I need someone with some experience on vcrypt (because I don't know if this question system is always the same with the same set of questions) and, as I've already said, someone who can give me an overview of the application and which components are already available to use.

Is there a way I can contact some developers?

ask here or in our IRC development channel on freenode #jdteam
brute forcing can be easily detected, also after the failure they give you a new challenge which will mean either guess again.

best bet would be just asking the question in the dialog and asking user to respond. Which is what you're already doing, manually.
