[Solved in JD2] Reverse link analysis

But how should they know if a link is B64 encoded if they have no good computer knowledge?
However, JD is open source and help is always welcome.
You can contact Coalado in our Supportchat (IRC) and ask him if you can help.

Well, I can email them with the configuration setting they will need, or it can be just posted somewhere in the web or in the jD forum where they can search for it.
All they will have to do is to configure JD once (and maybe update it once in a while).
Checking whether the link is encoded in B64 or hex is not that hard , see (encoded text extracted from previous post):
"687474703a2f2f7777772e6d65676175706c6f61642e636f6d2f3f643d4a513641423431" => starts with 687474703a2f2f that decodes to "**External links are only visible to Support Staff** using hex decoder. So if a regex pattern like "687474703a2f2f[0-9a-f]+" (could include a minimum size too)
"aHR0cDovL2dvby5nbC9HSjdRdA==" => starts with aHROcDov that decodes to "http:/" using B64 decoder. Besides that, it usually ends with "==", so the pattern would be something like "aHR0cDov\w+".
These patterns could come preconfigured and/or commented out in jD.

You should check out the SVN and see how it is implemented and see if you find things you would add^^

Think Jiaz said its all done already, or said he can use the same method for reverse/base along with most other methods ;> Check out the svn and test it for yourself. Jiaz was very quick in implementing this yesterday as I brought the topic up of how to attack/approach this problem, thinking I might code it. Like 30minutes later he'd done it. Just testing now as I haven't been able to start alpha due to non associated bugs.

tested:
reversed links = working
links as hex = working
links as base64 = not sure don't have a working example to test with..

@lfkpoa

Thanks for helping us to understand the issues.

@Jiaz

Thanks for already implementing it. I hope the Brazilians can soon use it.

@raztoki

Thanks for testing it.

The link **External links are only visible to Support Staff****External links are only visible to Support Staff**
leads to a downloading software, but according to lfkpoa the link after the "id/" should contain a base 64 encoded link :- **External links are only visible to Support Staff****External links are only visible to Support Staff** . It leads to a MU link.

[raztoki]

Must have copied the link wrongly earlier, couldn't get it to open in opera previously. I'll see what the go is with base decoding when Jiaz responds =].

'soon use it' will probably be when version 1 comes beta and/or stable.

You have to wait at least 2,5 months!

New "link protectors" started surfacing in a few download blogs, at least in Brazil, where the blog owner puts them in place so he can earn money from it, while the user is obliged to register his cell phone in order to proceed with the download.

An exemple of this is here: **External links are only visible to Support Staff****External links are only visible to Support Staff**

In this case, it'd be fairly simple for JDownloader: simply reverse the latter part of the link.

It would be nice to see some support for these kinds of links in the next update pack, if possible.

Cheers!

Merged reverse link stuff!

GreeZ pspzockerscene

I don't quite understand. Was this solved?

If so, why isn't it avaliable for updating yet?

[pspzockerscene]

Please read the upper posts!

solved is in respect to it getting implemented, you will just need to wait for the next major update. The tag was set prior to us making new tags, we set solved to issues resolved within our forums. I've now set one of the newer tags, maybe this will make it clearer.

All right, that does make it clearer, thanks!

Cheers.
