Hello everyone,

I stumbled upon the howto:
http://en.opensuse.org/Encrypted_Root_File_System

very good work, although my questions are:

1.) Is it possible to use other forms of encryption e.g. "Twofish" or
"Serpent" instead of the described AES "Rijndael" ??

their is a description of this in the gentoo wiki (I know it isnt suse but
for reference sake)
http://gentoo-wiki.com/SECURITY_System_Encryption_DM-Crypt_with_LUKS#FAQ

does suse by default support Twofish or Serpent or does one have to first
recompile the default kernel and add the modules.

2.) has anyone done this ? Either the methods described in the howto or
used another encryption algorithm ? Any noticeable performance losses ?

3.) I have seen in the opensuse 11.0 release notes that the default install
will support encrypting the root filesystem. Is it only supporting AES or
will the User be able to choose his encryption algorithm as well as key
lengths other options etc etc.

Thank You
