== Name

cryptsetup-tcryptDump - dump the header information of a TCRYPT (TrueCrypt or VeraCrypt compatible) device

== SYNOPSIS

*cryptsetup _tcryptDump_ [<options>] <device>*

== DESCRIPTION

Dump the header information of a TCRYPT (TrueCrypt or VeraCrypt compatible) device.

If the --dump-volume-key option is used, the TCRYPT device volume key is dumped instead of the TCRYPT header info.
Beware that the volume key (or concatenated volume keys if a cipher chain is used) can be used to decrypt the data stored in the TCRYPT container without a passphrase.
This means that if the volume key is compromised, the whole device has to be erased to prevent further access.
Use this option carefully.

The --key-file option allows a combination of file content with the passphrase
The --key-file option can be repeated.
Note that using keyfiles differs from LUKS keyfile logic.

*<options>* can be [--dump-volume-key, --key-file, --tcrypt-hidden, --tcrypt-system, --tcrypt-backup, --veracrypt (ignored), --disable-veracrypt, --veracrypt-pim, --veracrypt-query-pim, --cipher, --hash, --header, --verify-passphrase, --timeout].
