  int (* digest) (struct shash_desc *desc, const u8 *data,unsigned int len, u8 *out);
  int (* export) (struct shash_desc *desc, void *out);
  int (* import) (struct shash_desc *desc, const void *in);
  int (* setkey) (struct crypto_shash *tfm, const u8 *key,unsigned int keylen);
  unsigned int descsize;
  unsigned int digestsize;
  unsigned int statesize;
