Link-Containers are encrypted linklists. Using Containerfiles, it is very comfortable to provide many links at once. Moreover a encrypted container hides it's links from curious eyes. There are three different container formats: DLC, CCF (Cryptloads's containerformat, broken) and RSDF (Rapidshare Downloader Format, broken). JDownloader can handle all of them. DLC :Download Link Container , After RSDF and CCF got cracked, the JD-team decided to create a new Containerformat with the objectives to allow anybody to create DLCs and to allow every Loader to read DLCs. In order to live up to those expectations DLC uses a client-server encryption. Links are processed locally while the keys are distributed and recrypted by a webservice. To date, the DLC encryption has not been broken.
