Since you appear to be using Mandrake that includes loop-AES, AES encryption type is unhashed and password length determines actual number of key bits used to encrypt. AES128, AES192 and AES256 encryption types hash password with SHA-256, SHA-384 or SHA-512 and use specified number key bits to encrypt regardless of password length. Same AES cipher is used in all cases, only key is set up differently. For new setups, use AES128, AES192 or AES256, and specify password seed with 'mount -o pseed=xxxxxxxxxx' or 'losetup -S xxxxxxxxxx'.
