Adding to Milan Broz's answer, you can always use a simple file (or a sparse file) as a backing device for a LUKS container. Doing so will also tell you that the utilities can understand all other options you're feeding them, which may be a consideration if you are providing custom settings (for example, hash algorithm, encryption algorithm, etc.). Just remember to close the container before you delete the file. -- Michael Kjörling • https://michael.kjorling.se • michael@xxxxxxxxxxx “People who think they know everything really annoy those of us who know we don’t.” (Bjarne Stroustrup) _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
