CRYPTO_SHASH_DIGEST(9)                Programming Interface                CRYPTO_SHASH_DIGEST(9)



NAME
       crypto_shash_digest - calculate message digest for buffer

SYNOPSIS
       int crypto_shash_digest(struct shash_desc * desc, const u8 * data, unsigned int len,
                               u8 * out);

ARGUMENTS
       desc
           see crypto_shash_final

       data
           see crypto_shash_update

       len
           see crypto_shash_update

       out
           see crypto_shash_final

DESCRIPTION
       This function is a “short-hand” for the function calls of crypto_shash_init,
       crypto_shash_update and crypto_shash_final. The parameters have the same meaning as
       discussed for those separate three functions.

RETURN
       0 if the message digest creation was successful; < 0 if an error occurred
