The last -part of the message is specified by the -.I msg -parameter, and its byte-size is specified by the -.I msglen -parameter. If all of the message has already be processed -by calls to the -.BR libkeccak_hmac_update (3) -function or the -.BR libkeccak_hmac_fast_update (3) -function (with the same pointer on -.IR state ,) -.I msg -and -.I msglen -should be set to -.I NULL -and 0, respectively. -.PP -If the message is not comprised a whole number of bytes, -the number of bits, modulus 8, in the message should be -specified in the -.I bits -parameter. -.I msglen -must only count the number of whole bytes, that is, the -floor of the number of bits in the message divided by 8. -.PP -.I suffix -should be a NUL-terminated string of ASCII '1':s -and '0':s, representing the bits that should be appended -to the message. If this string is empty, -.I NULL -may be used instead. This is used to select hash algorithm. -For pure Keccak, -.I NULL -or \(dq\(dq is used. For the other algorithms the constants -.B LIBKECCAK_SHA3_SUFFIX -(for SHA-3), -.B LIBKECCAK_RAWSHAKE_SUFFIX -(for RawSHAKE), and -.B LIBKECCAK_SHAKE_SUFFIX -(for SHAKE) are used. -.PP -The hash of the message will be stored to -.IR hashsum , -unless -.I hashsum -is -.I NULL -(which increases the performance of the call.) A total of -.RI (( state->n -+ 7) / 8) bytes will be written to the beginning of -.IR hashsum . -Therefore, -.I hashsum -needs at least an allocation size of that number of bytes. -.PP -The -.BR libkeccak_hmac_fast_digest () -function may reallocate the state's message chunk buffer. -When doing so, it attempts to do so as quickly as possible, -rather than ensuring that the information in the old -allocation is securely removed if a new allocation is required. -.SH RETURN VALUES -The -.BR libkeccak_hmac_fast_digest () -function returns 0 upon successful completion. On error, --1 is returned and -.I errno -is set to describe the error. -.SH ERRORS -The -.BR libkeccak_hmac_fast_digest () -function may fail for any reason specified by the function -.BR realloc (3). -.SH SEE ALSO -.BR libkeccak_hmac_create (3), -.BR libkeccak_hmac_initialise (3), -.BR libkeccak_hmac_fast_update (3), -.BR libkeccak_hmac_fast_digest (3) -- cgit v1.2.3-70-g09d2
