2015-12-20	keys, trusted: seal with a TPM2 authorization policy	Jarkko Sakkinen	1	-14/+20
	TPM2 supports authorization policies, which are essentially combinational logic statements repsenting the conditions where the data can be unsealed based on the TPM state. This patch enables to use authorization policies to seal trusted keys. Two following new options have been added for trusted keys: * 'policydigest=': provide an auth policy digest for sealing. * 'policyhandle=': provide a policy session handle for unsealing. If 'hash=' option is supplied after 'policydigest=' option, this will result an error because the state of the option would become mixed.

2015-12-20	keys, trusted: select hash algorithm for TPM2 chips	Jarkko Sakkinen	1	-0/+3
	Added 'hash=' option for selecting the hash algorithm for add_key() syscall and documentation for it. Added entry for sm3-256 to the following tables in order to support TPM_ALG_SM3_256: * hash_algo_name * hash_digest_size Includes support for the following hash algorithms: * sha1 * sha256 * sha384 * sha512 * sm3-256 Signed-off-by: Jarkko Sakkinen <jarkko.sakkinen@linux.intel.com> Tested-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: James Morris <james.l.morris@oracle.com> Reviewed-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Acked-by: Peter Huewe <peterhuewe@gmx.de>

2011-09-27	doc: fix broken references	Paul Bolle	1	-1/+2
	There are numerous broken references to Documentation files (in other Documentation files, in comments, etc.). These broken references are caused by typo's in the references, and by renames or removals of the Documentation files. Some broken references are simply odd. Fix these broken references, sometimes by dropping the irrelevant text they were part of. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-06-27	encrypted-keys: add ecryptfs format support	Roberto Sassu	1	-2/+4
	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'.

2011-06-27	encrypted-keys: add key format support	Roberto Sassu	1	-18/+30
	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.
