AMFNV1a - constexpr implementation of FNV1a hash algorithmThere are two variants, 32 and 64 bit. If parameter string is an constexpr expression, result is also constexpr expression.

Usage

Let's have this table. First word is an original string, second is a "translated" string.

#include "amfnv1a/AMCEFNV1a.h"
#include <iostream>
 
using namespace AMCore;
using namespace std;
 
int main() {
    cout<<"Enter password (color of blood): ";
    char pass[1024];
    cin>>pass;
    uint64_t hash = AMFNV1aAlgorithm::fnv1a64(pass);
 
    switch (hash)
    {
         case AMCEFNV1aAlgorithm::fnv1a64("blue"): cout<<"Fail"<<endl;break;
         case AMCEFNV1aAlgorithm::fnv1a64("green"): cout<<"Fail"<<endl;break;
         case AMCEFNV1aAlgorithm::fnv1a64("red"): cout<<"Hooray!"<<endl;break;
         case AMCEFNV1aAlgorithm::fnv1a64("yellow"): cout<<"Fail"<<endl;break;
         default: cout<<"Fail"<<endl;
    }
    return 0;
 }
