@logn cites a couple links explaining how CryptoLocker worked[1]. Each file gets its own key, and those keys are stored on the victim's computer, encrypted with a single key. DeCryptoLocker can defeat the encryption and restore your files[2]. Symantec says CryptoWall similarly uses public-key encryption with a 2048-byte key[3], but no indication if it can be defeated like CryptoLocker was.
