+== Name
+
+cryptsetup-luksFormat - initialize a LUKS partition and set the initial passphrase
+
+== SYNOPSIS
+
+*cryptsetup _luksFormat_ [<options>] <device> [<key file>]*
+
+== DESCRIPTION
+
+Initializes a LUKS partition and sets the initial passphrase (for
+key-slot 0), either via prompting or via <key file>. Note that if the
+second argument is present, then the passphrase is taken from the file
+given there, without the need to use the --key-file option. Also note
+that for both forms of reading the passphrase from a file you can give
+'-' as file name, which results in the passphrase being read from stdin
+and the safety-question being skipped.
+
+You cannot call luksFormat on a device or filesystem that is mapped or
+in use, e.g., mounted filesystem, used in LVM, active RAID member, etc. The
+device or filesystem has to be un-mounted in order to call luksFormat.
+
+To use specific version of LUKS format, use _--type luks1_ or _type luks2_.
+
+*<options>* can be [--hash, --cipher, --verify-passphrase, --key-size,
+--key-slot, --key-file (takes precedence over optional second argument),
+--keyfile-offset, --keyfile-size, --use-random, --use-urandom, --uuid,
+--volume-key-file, --iter-time, --header, --pbkdf-force-iterations,
+--force-password, --disable-locks, --timeout, --type, --offset,
+--align-payload (deprecated)].
+
+For LUKS2, additional *<options>* can be [--integrity,
+--integrity-no-wipe, --sector-size, --label, --subsystem, --pbkdf,
+--pbkdf-memory, --pbkdf-parallel, --disable-locks, --disable-keyring,
+--luks2-metadata-size, --luks2-keyslots-size, --keyslot-cipher,
+--keyslot-key-size, --integrity-legacy-padding].
+
+*WARNING:* Doing a luksFormat on an existing LUKS container will make
+all data in the old container permanently irretrievable unless you have a
+header backup.
