This patch introduces the new format 'ecryptfs' that allows to store an authentication token structure inside the encrypted key payload containing a randomly generated symmetric key, as the same for the format 'default'.

The 'encrypted' key type defines its own payload format which contains a
symmetric key randomly generated that cannot be used directly to mount
an eCryptfs filesystem, because it expects an authentication token
structure.

This patch introduces the new format 'ecryptfs' that allows to store an
authentication token structure inside the encrypted key payload containing
a randomly generated symmetric key, as the same for the format 'default'.

More details about the usage of encrypted keys with the eCryptfs
filesystem can be found in the file 'Documentation/keys-ecryptfs.txt'.

encrypted-keys: add key format support 2011-06-27T13:10:45+00:00 Roberto Sassu roberto.sassu@polito.it 2011-06-27T11:45:42+00:00 4e561d388feff18e4b798cef6a1a84a2cc7f20c2 This patch introduces a new parameter, called 'format', that defines the format of data stored by encrypted keys. The 'default' format identifies encrypted keys containing only the symmetric key, while other formats can be defined to support additional information. The 'format' parameter is written in the datablob produced by commands 'keyctl print' or 'keyctl pipe' and is integrity protected by the HMAC.
