cryptsetup-luksConvertKey - converts an existing LUKS2 keyslot to new PBKDF parameters
|
|
|
|
== SYNOPSIS
|
|
|
|
*cryptsetup _luksConvertKey_ [<options>] <device>*
|
|
|
|
== DESCRIPTION
|
|
|
|
Converts an existing LUKS2 keyslot to new PBKDF parameters.
|
|
The passphrase for keyslot to be converted must be supplied interactively or via --key-file.
|
|
If no --pbkdf parameters are specified LUKS2 default PBKDF values will apply.
|
|
|
|
If a keyslot is specified (via --key-slot), the passphrase for that keyslot must be given.
|
|
If no keyslot is specified and there is still a free keyslot, then the new parameters will be put into a free keyslot before the keyslot containing the old parameters is purged.
|
|
If there is no free keyslot, then the keyslot with the old parameters is overwritten directly.
|
|
|
|
*WARNING:* If a keyslot is overwritten, a media failure during this operation can cause the overwrite to fail after the old parameters have been wiped and make the LUKS container inaccessible.
|
|
|
|
*<options>* can be [--key-file, --keyfile-offset, --keyfile-size, --key-slot, --hash, --header, --disable-locks, --iter-time, --pbkdf, --pbkdf-force-iterations, --pbkdf-memory, --pbkdf-parallel, --keyslot-cipher, --keyslot-key-size, --timeout, --verify-passphrase].
