CRYPTSETUP-ERASE(8)                     Maintenance Commands                     CRYPTSETUP-ERASE(8)

NAME
       cryptsetup-erase, cryptsetup-luksErase - erase all keyslots

SYNOPSIS
       cryptsetup  erase [<options>] <device>
       cryptsetup luksErase [<options>] <device>

DESCRIPTION
       Erase all keyslots and make the LUKS container permanently inaccessible. Unless the device is
       configured with HW OPAL support you do not need to provide any password for this operation.

       WARNING: This operation is irreversible.

       WARNING: with --hw-opal-factory-reset ALL data is lost on the device, regardless of the
       partition it is ran on, if any, and regardless of any LUKS2 header backup, and does not
       require a valid LUKS2 header to be present on the device to run.

       <options> can be [--header, --disable-locks, --hw-opal-factory-reset, --key-file].

OPTIONS
       --key-file, -d name (LUKS2 with HW OPAL only)
           Read the Admin PIN or PSID (with --hw-opal-factory-reset) from file depending on options
           used.

           If the name given is "-", then the secret will be read from stdin. In this case, reading
           will not stop at newline characters.

       --header <device or file storing the LUKS header>
           Use to specify detached LUKS2 header when erasing HW OPAL enabled data device.

       --disable-locks
           Disable lock protection for metadata on disk. This option is valid only for LUKS2 and
           ignored for other formats.

           WARNING: Do not use this option unless you run cryptsetup in a restricted environment
           where locking is impossible to perform (where /run directory cannot be used).

       --batch-mode, -q
           Suppresses all confirmation questions. Use with care!

           If the --verify-passphrase option is not specified, this option also switches off the
           passphrase verification.

       --debug or --debug-json
           Run in debug mode with full diagnostic logs. Debug output lines are always prefixed by #.

           If --debug-json is used, additional LUKS2 JSON data structures are printed.

       --version, -V
           Show the program version.

       --usage
           Show short option help.

       --help, -?
           Show help text and default parameters.
