Hi! I was looking at feature comparison charts.
GBDE uses AES, GELI can uses AES, Blowfish, and 3DES.
GBDE uses fixed key length, GELI can be variable.

Since they both can do sector-by-sector
encryption, and GELI can be configured to use
the same scheme and key length as GBDE,
I just thought maybe it would be great if
they're compatible.

(I have a lot of data encrypted using GBDE,
and it would be a lot of work to
re-encrypt them with GELI to get the ability
to enter keyphrase in kernel space
rather than userspace, so that I can encrypt
the root filesystem which GBDE can't do)

Thanks!
