* digest: allow algo to specify their length at runtimeJean-Christophe PLAGNIOL-VILLARD2015-03-271-2/+1
| | | | | | | | such as RSA as we load a DER key we will detect the key size at runtime and so the algo length. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* command: add generic digest commandJean-Christophe PLAGNIOL-VILLARD2015-03-201-5/+20
| | | | | | | That can be used for digest calculation and verify Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* digest: add digest callbackJean-Christophe PLAGNIOL-VILLARD2015-03-191-0/+18
| | | | | | | | | | | Combination of @init and @update and @final. This function effectively behaves as the entire chain of operations, @init, @update and @final issued in sequence. This is added for hardware which cannot do even the @finup, but can only do the whole transformation in one run.

* digest: add verify callbackJean-Christophe PLAGNIOL-VILLARD2015-03-191-1/+23
| | | | | | | | | | | | this will allow to compare a md with the original one When calling this do not call final For RSA_SIGN verification final does not exist only verify as final will be for signing Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* crypto: digest: Fix coding styleSascha Hauer2015-03-131-4/+4
| | | | | | | | | | When declaring pointer data or a function that returns a pointer type, the preferred use of '*' is adjacent to the data name or function name and not adjacent to the type name. Fix the remaining occurences in crypto/ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* crypto: digest: Make string arguments constSascha Hauer2015-03-131-9/+9
| | | | | | | Most string arguments for keys and filenames can be const. Change that. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* digest: make it multi-instanceJean-Christophe PLAGNIOL-VILLARD2015-03-121-10/+53
| | | | | | | | | | Now you need to call digest_alloc and when you finish to use it digest_free. We need this for upcomming aes encryption support and secure boot as we will need multiple instance of the same digest.

* digest: introduce digest_{init/update/final/length}Jean-Christophe PLAGNIOL-VILLARD2015-03-121-3/+3
| | | | | | | | This will allow to move from a one at a time digest to a multi-instance with too much impact on the code using it Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
