Just an update - I exchanged some messages with Mike; they were interested in getting me the details I needed in order to write something (like the key derivation function and parameters they’re using), but they were also pretty busy with the 6.1 release at the time. I’ll check back in with them after 6.1’s out the door. Just to set expectations, though - I’m not planning to release anything without their approval, and they haven’t said anything along those lines yet. So this might come to nothing… but we can hope. :-)
