Iv forgot a backup password that is encrypt.

Is there a way that i can crack the password to get my backup? Iv tried every password i can think of but its no use. Is there any softwares that i can use to crack the code? Im using a mac book pro to do this, not windows if your asking. Iv remembered setting up the encrypt password with a keychain in case if i forgot it and it would remind me but theres no option to use that keychain to get my password. At this point im clueless and i need help because this backup is VERY important to me! Should i take my stuff to the apple store; to the genius bar and ask for help? Please help me out!
