It's possible to decrypt dlc, ccf and rsdf containers, currently. We don't think there are much more out there so far.
After RSDF and CCF got cracked, the JDownloader-team decided to create a new Containerformat. DLC uses a client-server encryption. Links are processed locally while the keys are distributed and recrypted by a webservice.
CCF was designed to be a Cryptload-only format. Inside a CCF, urls are stored in a XML. Beside urls, a ccf often contains passwords an comments. There are 5 different ccf versions around.
RSDF was introduced by Schneewiesel. A RSDF container contains a AES-encrypted linklist. Beside urls, it's not possible to store any other information in a RSDF.
You have to make sure, that it's a real download link and doesn't need a special session or a cookie. A container you can download after answering a captcha will not work. But you can download it an reupload it here. That will always work.
This site should be a protest against the dlc container. This container just sucks. You're totally depending on a server/service to get your decryption key. The try to stop link abusers fails here. It only slows them a little down, but harms all other users at the same time. If you just take a little time a have look at this system, you'll see that's easy to pass by. CnL/CnL2 are even easier bypassed than the DLC containers.
