There is a software out there (not saying any names) that cracks WPA/AES/TKIP with ease...
so...just for further reference.
No there isn't. If there was such thing the NSA (you know who the NSA is right?) would not recommend AES encryption for security. If the military puts whatever giant death robot they are building blue prints in AES encrypted images it is probably safe.
What you are talking about is brute force attacks or dictionary attacks which is what I already mentioned. If you don't use crappy passwords WPA encryption can not be hacked or cracked.
Here goes some light reading for you.

Further more, if AES encryption were so easily broken do you think Microsoft, Apple, and Sun would use it to encrypt their passwords with their directory services? If it was so easily hacked then they wouldn't use it all, and all of them use it to store passwords in LDAP.
I suppose you are referring to prebuilt hacking tools like backrack? In some aspects AES can be cracked, but AES itself is not crackable, but if someone implements it in a manner with security holes then yes it can be crackable.
Of course computers are not powerful enough to crack AES at this day in age so it is not likely you are going to crack AES.
After all, the NSA is offering a billion dollars open to anyone that can crack AES because they want to tap into skype calls. Skype uses AES encryption. I am sure if the NSA is offering a billion dollars to crack it, it is not crackable.
