    crypto: sha1 - implement base layer for SHA-1 · c4d5b9ff
    Ard Biesheuvel authored
    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.
