Check out sslviewd, it can do decrypt of traffic (on the fly).   You may be able to use that to either generate clear text captures or replay the encrypted dump through it into a Bro instance listening to the output. 

On another note, Wireshark has some capacity to carve files out, within it, while I know I'd like to use Bro, if it's a one shot deal, that may be an easier method.
