Comment 1 for bug 993761

Forgot to say that in my POV the biggest problem is the installer asks passphrases about encrypted partitions that already exist in the disk. That should not happens, it should only handle (and ask passphrases) for the encrypted partitions that are created during the install proccess.

This way would be irrelevant if the installer would or not support other cyphers.
Still would be better that the installer could also handle the benbi cypher since its the most secure, please refer to http://www.ody.ca/~dwhodgins/Luks-Howto.html#Changelog
