Loop-AES and kerneli.org-cryptoapi use same on-disk format, but userspace
tools need different options. To mount AES encrypted volumes created with
kerneli.org-cryptoapi in loop-AES, use mount option -o phash=rmd160 or
losetup option -H rmd160, and specify cipher name as AES128, AES192 or
AES256.

Mandrake kernel AES on-disk format and userspace command options are 100%
compatible with loop-AES.

SuSE kernel twofish uses different on-disk format. Twofish loop cipher
module in loop-AES' ciphers add-on package is compatible with SuSE kernel
twofish if appropriate options are given to mount or losetup.

Kernel 2.5/2.6 on-disk formats are same as before.
