The hash -algorithm tuning is specified by -.IR *spec . -.PP -The hash is stored in binary form to -.IR hashsum . -.I hashsum -should have an allocation size of at least -.RI ((( spec->output -+ 7) / 8) * sizeof(char)). -.PP -.I *state -should not be initialised. -.BR libkeccak_keccaksum_fd () -initialises -.I *state -itself. Therefore there would be a memory leak if -.I *state -is already initialised. -.SH RETURN VALUES -The -.BR libkeccak_keccaksum_fd () -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_keccaksum_fd () -function may fail for any reason, except those resulting -in -.I errno -being set to -.BR EINTR , -specified for the functions -.BR read (2), -.BR malloc (3), -and -.BR realloc (3). -.SH NOTES -Be aware, -.BR libkeccak_keccaksum_fd () -hashes the file until the end has been reached. For pipes -and sockets and this means until the file has been closed. -But for character devices, this usually means never. -Attempting to hash files in /dev is therefore usually a -bad idea. -.BR libkeccak_keccaksum_fd () -does not check for the file length or file type before -hashing as this could limit what you can do, and make -the library more complex. -.PP -.BR libkeccak_keccaksum_fd () -does not stop if interrupted -.RI ( read (2) -returns -.BR EINTR .) -.PP -.BR libkeccak_keccaksum_fd () -assumes all information is non-sensitive, and will -therefore not perform any secure erasure of information. -.PP -.BR libkeccak_keccaksum_fd () -does not validate the tuning of the algorithm. -.SH EXAMPLE -This example calculates the Keccak[b = 1024, c = 576, n = 256] -hash of the input from stdin, and prints the hash, in hexadecimal -form, to stdout. -.LP -.nf -libkeccak_state_t state; -libkeccak_spec_t spec; -char binhash[256 / 8]; -char hexhash[256 / 8 * 2 + 1]; - -spec.bitrate = 1024; -spec.capacity = 576; -spec.output = 256; - -if (libkeccak_keccaksum_fd(STDIN_FILENO, &state, &spec, binhash) < 0) - goto fail; -libkeccak_behex_lower(hexhash, binhash, sizeof(binhash)); -printf(\(dq%s\en\(dq, hexhash); -libkeccak_state_destroy(&state); -.fi -.SH SEE ALSO -.BR libkeccak_behex_lower (3), -.BR libkeccak_behex_upper (3), -.BR libkeccak_generalised_sum_fd (3), -.BR libkeccak_sha3sum_fd (3), -.BR libkeccak_rawshakesum_fd (3), -.BR libkeccak_shakesum_fd (3), -.BR libkeccak_spec_check (3), -.BR libkeccak_generalised_spec_initialise (3), -.BR libkeccak_state_initialise (3) -- cgit v1.2.3-70-g09d2
