Utilities

• bin/make-encrypted-dev: Prepare removable drives and disk images, then create LUKS encrypted file systems on them.

• bin/make-encrypted-disk-image

  Create an encrypted disk image. The image is a LUKS encrypted file that contains an EXT4 file system.

  It can be mounted with bin/mount-encrypted-dev.

• bin/mount-encrypted-dev: Mount (and ummount) devices/images created by the make-encrypted-dev and make-encrypted-disk-image scripts.

• bin/extend-subkey-expiration-date.sh: Mostly automate the process of booting into a machine with no network and extending the expiration date of your subkeys.
