NAME         top

       cryptsetup-erase, cryptsetup-luksErase - erase all keyslots

SYNOPSIS         top

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

DESCRIPTION         top

       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

       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         top

       --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.

           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).

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

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

           Erase ALL data on the OPAL self-encrypted device, regardless
           of the partition it is ran on, if any, and does not require a
           valid LUKS2 header to be present on the device to run. After
           providing correct PSID via interactive prompt or via
           --key-file parameter the device is erased. PSID is usually
           printed on the OPAL device label (either directly or as a QR

       --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

           Show short option help.

       --version, -V
           Show the program version.
