Do a complete backup of your existing data now, and you'll be able to recover your encrypted partition after a reformatting later. > or it will be much more easier to copy those data somewhere else and > create a new encrypted disk?

Without the correct passphrase, and without any hackish memory manipulation and similar, the only way is to copy your data to a safe place and to recreate your encrypted device later. To unlock/decrypt the master key, you have to provide the correct passphrase first. > But I am wondering since key need to be in a memory somewhere there > could be a way... :) You can read here how it works: http://cryptsetup.googlecode.com/svn-history/r42/wiki/LUKS-standard/on-disk-format.pdf _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
