In the 7.0 source code there are two versions of the function that
computes that hash, so I guess that 6.3 is back-compatible with
6.1, but that a 6.3 geli-device can't be read  by 6.1.

If this is a removable drive that needs to inter-operate, I would
suggest that you dump the data, and create a new geli device under 6.1.
