crypto: hash - add zero length message hash for shax and md5

2015-12-22T12:43:35+00:00

Some crypto drivers cannot process empty data message and return a
precalculated hash for md5/sha1/sha224/sha256.

This patch add thoses precalculated hash in include/crypto.

crypto: sha512-generic - move to generic glue implementation

2015-04-10T13:39:41+00:00

This updated the generic SHA-512 implementation to use the
generic shared SHA-512 glue code.

It also implements a .finup hook crypto_sha512_finup() and exports
it to other modules. The import and export() functions and the
.statesize member are dropped, since the default implementation
is perfectly suitable for this module.

crypto: sha256-generic - move to generic glue implementation

2015-04-10T13:39:41+00:00

This updates the generic SHA-256 implementation to use the
new shared SHA-256 glue code.

It also implements a .finup hook crypto_sha256_finup() and exports
it to other modules. The import and export() functions and the

crypto: sha1-generic - move to generic glue implementation

2015-04-10T13:39:40+00:00

This updated the generic SHA-1 implementation to use the generic
shared SHA-1 glue code.

It also implements a .finup hook crypto_sha1_finup() and exports
it to other modules. The import and export() functions and the
.statesize member are dropped, since the default implementation
is perfectly suitable for this module.

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.

This patch fixes this by providing a declaration for struct shash_desc.
