CRYPTO_SHASH_FINAL(9)                 Programming Interface                 CRYPTO_SHASH_FINAL(9)



NAME
       crypto_shash_final - calculate message digest

SYNOPSIS
       int crypto_shash_final(struct shash_desc * desc, u8 * out);

ARGUMENTS
       desc
           operational state handle that is already filled with data

       out
           output buffer filled with the message digest

DESCRIPTION
       Finalize the message digest operation and create the message digest based on all data
       added to the cipher handle. The message digest is placed into the output buffer. The
       caller must ensure that the output buffer is large enough by using
       crypto_shash_digestsize.

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