Hello, someone know why mga9 use benbi initialization vector instead plain64 by default for encrypting disk?

Hi there,
just checked the package and there's nothing relevant that we're changing about the default settings.
See http://svnweb.mageia.org/packages/cauld ... arkup#l101

Also, are you asking about creating encrpyted filesystems via diskdrake or manually via LUKS ?
And why do you suggest it should be plain64 as initialisation vector?

are you asking about creating encrpyted filesystems via diskdrake

yes, diskdrake use benbi. Manually, via cryptsetup (luks), I can choice and on mga5 I had a chosen "plain" initialization vector.
According to the information I found, the difference between them is that "benbi" uses "big-endian" and "plain"/"plain64" uses "little-endian" bytes order.
Intel and AMD processors uses little-endian byte order so maybe work faster with luks encryption plain initialization vector. But maybe there are other reasons, e.g. better safety to use "benbi".
