      If you want have a look at source code of a program able to deal with RAR files than check out 7-Zip[^] sources. On the other hand if you wish to hack a password-protected RAR file, I doubt you are going to get help here. :)

                You can't do this. RAR is a proprietary file format and you need to buy a licence in order to get details of it.

                  That's incorrect. The LZMA sdk (which 7zip uses) can be used to de-compress a RAR file. It's just that the RAR compression has been kept closed-source/proprietary or such.

                    CPallini's answer is correct. You could use the LZMA sdk to de-compress a RAR file. Whether the file has password or not is irrelevant (the SDK has methods for all such cases). If you have a more specific question, ask it in the sourceforge page for 7zip.

                          No problem. Technically, unRAR[^] is to be used for de-compressing a RAR file, but I recommended the LZMA SDK, becuase it uses the same code too, and it can do a lot of other things in addition to handling RAR files. :)
