[Cooker] Encrypted partitions with Mandrake?

[lamikr_mdk]

Can anybody give me details how strong is the encryption if I create 
encrypted mount point partition during the Mandrake install?

Or should I use some PKI based loopback crypto package like loop-AES. 
See http://loop-aes.sourceforge.net/loop-AES.README for details?

Has anybody had any experiences from either of these? Or from some other 
encrypted loop device solutions?
