i read tc switched from cbc for security reasons. i am curious why my
fav cipher only uses cbc when its been said to be less secure?
is any sec iv more secure than others?
thanks for any input or advice.
FreeOTFE only uses CBC if the user *explicitly* selects it.
By default, FreeOTFE uses XTS (specifically, XTS-AES-256 - the IEEE
standard for disk encryption). If your favourite cypher is less secure, you
might want to reconsider your choice of favourite cypher.
For the vast majority of users though, the cypher mode is unlikely to make
any real difference - with modern cyphers, the weakest link in the chain is
generally not the encryption system.
