STRUCT HASH_ALG_COMM(9)               Programming Interface               STRUCT HASH_ALG_COMM(9)



NAME
       struct_hash_alg_common - define properties of message digest

SYNOPSIS
       struct hash_alg_common {
         unsigned int digestsize;
         unsigned int statesize;
         struct crypto_alg base;
       };

MEMBERS
       digestsize
           Size of the result of the transformation. A buffer of this size must be available to
           the final and finup calls, so they can store the resulting hash into it. For various
           predefined sizes, search include/crypto/ using git grep _DIGEST_SIZE include/crypto.

       statesize
           Size of the block for partial state of the transformation. A buffer of this size must
           be passed to the export function as it will save the partial state of the
           transformation into it. On the other side, the import function will load the state
           from a buffer of this size as well.

       base
           Start of data structure of cipher algorithm. The common data structure of crypto_alg
           contains information common to all ciphers. The hash_alg_common data structure now
           adds the hash-specific information.
