* [dm-crypt] Loading the LUKS header from an external source?

If those features are currently not available, plain dm-crypt seems preferrable mainly for plausible deniability reasons. Please consider this a feature request.

From the terminal,type "man cryptsetup" and then look for "--header" entry in the "OPTIONS" section.

Exactly and using external header also allows to set data offset to start of the disk, exactly what you want. All is also described in release notes for 1.4 http://code.google.com/p/cryptsetup/wiki/Cryptsetup140 Milan ^ permalink raw reply [flat|nested] 3+ messages in thread
