crypto: lib/sha256 - return void

2020-05-08T05:32:12+00:00

The SHA-256 / SHA-224 library functions can't fail, so remove the useless return value. Also long as the declarations are being changed anyway, also fix some parameter names in the declarations to match the definitions. Signed-off-by: Eric Biggers Reviewed-by: Jason A.

crypto: sha256 - Remove sha256/224_init code duplication

2019-09-05T04:54:54+00:00

lib/crypto/sha256.c and include/crypto/sha256_base.h define 99% identical functions to init a sha256_state struct for sha224 or sha256 use. This commit moves the functions from lib/crypto/sha256.c to include/crypto/sha.h (making them static inline) and makes the sha224/256_base_init static inline functions from include/crypto/sha256_base.h wrappers around the now also static inline include/crypto/sha.h functions.

crypto: sha256 - implement base layer for SHA-256

2015-04-10T13:39:39+00:00

To reduce the number of copies of boilerplate code throughout the tree, this patch implements generic glue for the SHA-256 algorithm. This allows a specific arch or hardware implementation to only implement the special handling that it needs. The users need to supply an implementation of void (sha256_block_fn)(struct sha256_state *sst, u8 const *src, int blocks) and pass it to the SHA-256 base functions. For easy casting between the prototype above and existing block functions that take a 'u32 state[]' as their first argument, the 'state' member of struct sha256_state is moved to the base of the struct.
