loop-AES cryptoloop interop

Hi,

I have a Question:

Why can't I read cryptoloop devices with loop-AES (and the other way round)

I have loop-AES-1.5c with the appropriate util-linux

and 

cryptoapi-2.4.18.1 with the appropriate util-linux


both work perfectly. 

BUT:

I can neither read cryptoloop devices with loop-AES nor loop-AES devices with cryptoapi.
Both use AES256 encryption with the same plaintext password. If I am right, they
use both the same plaintext to key funciton and both use 512 byte blocksize.

Since they dont interoperate, I dont know which one to choose. I dont want to discover in one year,
that the loop-X is no longer supported, but loop-Y cant read my drives. 


Another question:

Can I decrypt loop-XY with any other AES implementation like this ?
cat /dev/hdc99 | ase-generic -d > file 

is there another way to decrypt without the use of neither loop-AES/cryptoloop
(only using the function to extract the key from the plaintext)
