crypto: sha1_generic - Add export/import support This patch adds export/import support to sha1_generic. The exported type is defined by struct sha1_state, which is basically the entire descriptor state of sha1_generic. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224 Resubmitting this patch which extends sha256_generic.c to support SHA-224 as described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

crypto: sha1 - implement base layer for SHA-1 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.

I guess you need to include crypto/hash.h in crypto/sha.h. This patch fixes this by providing a declaration for struct shash_desc.

crypto: sha1 - export sha1_update for reuse Export the update function as crypto_sha1_update() to not have the need to reimplement the same algorithm for each SHA-1 implementation. This way the generic SHA-1 implementation can be used as fallback for other implementations that fail to run under certain circumstances, like the need for an FPU context while executing in IRQ context.
