linux-stable.git/include/crypto/sha1_base.h, branch linux-4.1.y Linux kernel stable tree crypto: sha1 - implement base layer for SHA-1 2015-04-10T13:39:39+00:00 Ard Biesheuvel ard.biesheuvel@linaro.org 2015-04-09T10:55:33+00:00 c4d5b9ffa31f7283b34cba991514dacae4c8d3de To reduce the number of copies of boilerplate code throughout the tree, this patch implements generic glue for the SHA-1 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 (sha1_block_fn)(struct sha1_state *sst, u8 const *src, int blocks) and pass it to the SHA-1 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 sha1_state is moved to the base of the struct.

To reduce the number of copies of boilerplate code throughout
the tree, this patch implements generic glue for the SHA-1
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 (sha1_block_fn)(struct sha1_state *sst, u8 const *src, int blocks)

and pass it to the SHA-1 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 sha1_state is
moved to the base of the struct.
