In plain dm-crypt mode, there is no encrypted master key on the device
(i.e., no metadata header). Is a master key derived from the user
passphrase and used to en-/decrypt the device? If yes, how to derive
the master key from the passphrase in plain mode?
The /cryptsetup/ manpage indicates that the key is just the hash of the
passphrase using the specified hash function and cropped to the required
key length. "cryptsetup --help" will show you the default hash function.
