11 cryptsetup-luksRemoveKey - remove the supplied passphrase from the LUKS device
15 *cryptsetup _luksRemoveKey_ [<options>] <device> [<key file with passphrase to be removed>]*
19 Removes the supplied passphrase from the LUKS device. The passphrase to
20 be removed can be specified interactively, as the positional argument or
23 *<options>* can be [--key-file, --keyfile-offset, --keyfile-size,
24 --header, --disable-locks, --type, --timeout, --verify-passphrase].
26 *WARNING:* If you read the passphrase from stdin (without further
27 argument or with '-' as an argument to --key-file), batch-mode (-q) will
28 be implicitly switched on and no warning will be given when you remove
29 the last remaining passphrase from a LUKS container. Removing the last
30 passphrase makes the LUKS container permanently inaccessible.
