Hi everyone,
I'm new here and I need need a bit help. I downloaded a .ISO that is crypted in a rar file. I'm supposed to go register to an hispanic site, what i've done, but their site is so bugged it is impossible to find the password to this file. So I tryed some password cracker, but the file is too big (about 2gig compress and 3 gig decompress) . I suppose they must be some kind of way to try to brute force without decompressing th whole file ( 15 minutes). There must be a way to recognize an non-bootable iso maybe or I don't know.

Thanks for your help !

P.S. Sorry for my english , it is my second language...
