crypto: sha - split sha.h into sha1.h and sha2.h

2020-11-20T03:45:33+00:00

Currently contains declarations for both SHA-1 and SHA-2, and contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split into two headers and , and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

crypto: hash - Use memzero_explicit() for clearing state

2020-10-30T06:35:03+00:00

Without the barrier_data() inside memzero_explicit(), the compiler may optimize away the state-clearing if it can tell that the state is not used afterwards. Signed-off-by: Arvind Sankar Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: sha512 - implement base layer for SHA-512

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-512 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 (sha512_block_fn)(struct sha512_state *sst, u8 const *src, int blocks) and pass it to the SHA-512 base functions. For easy casting between the prototype above and existing block functions that take a 'u64 state[]' as their first argument, the 'state' member of struct sha512_state is moved to the base of the struct.
