Tony Finch	cf715d488b	Suppress division by zero warning ... Coverity is optimistic that we might do thousands of hashes in less than a microsecond. /tests/bench/siphash.c: 54 in main() 48 count++; 49 } 50 51 isc_time_now_hires(&finish); 52 53 us = isc_time_microdiff(&finish, &start); >>> CID 358309: Integer handling issues (DIVIDE_BY_ZERO) >>> In expression "count * 1000UL / us", division by expression "us" which may be zero has undefined behavior. 54 printf("%f us wide-lower len %3zu, %7llu kh/s (%llx)\n", 55 (double)us / 1000000.0, len, 56 (unsigned long long)(count * 1000 / us), 57 (unsigned long long)sum); 58 } 59	2022-10-05 12:31:42 +01:00
Ondřej Surý	c14a4ac763	Add a case-insensitive option directly to siphash 2-4 implementation ... Formerly, the isc_hash32() would have to change the key in a local copy to make it case insensitive. Change the isc_siphash24() and isc_halfsiphash24() functions to lowercase the input directly when reading it from the memory and converting the uint8_t * array to 64-bit (respectively 32-bit numbers).	2022-10-04 10:32:40 +02:00
