* crypto: digest: Change the signature of digest_file_window()Andrey Smirnov2019-01-161-1/+1
| | | | | | | | | On 32-bit systems "ulong" will limit digest_file_window()'s maximum size to 4 GiB. Convert "start" and "size" to "loff_t" in order to be able to handle maximum file size supported by the rest of the system.

* digest.h: Sync hash_algo values with kernelSascha Hauer2018-10-081-1/+7
| | | | | | | | enum hash_algo is exported from the Kernel, so sync it with the numbers that are exported. Since we have barebox specific extensions to the hash_algo list add a big comment and put the extenstions at the end. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* crypto: add CRC32 digestYegor Yefremov2016-05-251-0/+1

* crypto: add digest_alloc_by_algo()Sascha Hauer2016-01-261-0/+23
| | | | | | | | | | | In barebox the function digest_alloc() allocates a digest based on a string. When a subsystem already uses an integer value to identify a digest it makes no sense to create a string and pass it to digest_alloc(), where it is parsed again. This patch adds the possibility to get a digest by an enum.

* crypto: prepare to allow multiple digest driverJean-Christophe PLAGNIOL-VILLARD2015-03-271-3/+9
| | | | | | | | | | This will allow to have hw driver or asm optimised driver. Use a priority level to determine which one to use at runtime. The generic one will be 0. 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/+8
| | | | | | | | | | | 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.
