Password Recovery(repost)(repost)(repost)

I need a password recovery core which can recover Zip, RAR, PDF, Word, Excel.... Let tell me what core you can provide. I prefer some of password remover without brute force attack. Here is PDF Password Recover without using brute force: [login to view URL] Some of protectors like ZIP, RAR... can use brute force. It's ok. I just need the core and I should be written by Delphi. If you use another language, please tell me how can I integrate into my Delphi application (maybe using DLL with callback) I don't want the GUI, just one function for checking Password. Eg: if IsPassword(mypass) then ... It will check CRC and call back to me is the password ok. Of course you need to give me the IsPassword source code. I just need the core, don't need the complete application. So, please advice the cheap price (maximum is 100$/product, not 100$ for all) ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details.
