Javascript。 将 MD5 哈希转换为整数

Question

是否可以在 Javascript d131dd02c5e6eec4 693d9a0698aff95c 2fcab58712467eab 4004583eb8fb7f89转换为整数： d131dd02c5e6eec4 693d9a0698aff95c 2fcab58712467eab 4004583eb8fb7f89 ，这是 MD5 哈希函数的结果？

Answer 1

May not be perfect, but this suited my needs

export function stringToIntHash(str, upperbound, lowerbound) {
  let result = 0;
  for (let i = 0; i < str.length; i++) {
    result = result + str.charCodeAt(i);
  }

  if (!lowerbound) lowerbound = 0;
  if (!upperbound) upperbound = 500;

  return (result % (upperbound - lowerbound)) + lowerbound;
}

Answer 2

That looks like a hexadecimal number, so you could try using the parseInt function and pass in a base of sixteen:

var num = parseInt(string, 16);

Edit: This method doesn't actually work. See the comments for details.

Answer 3

Maybe this one https://github.com/lovell/farmhash ?

const farmhash = require('farmhash');
const hexDigest = crypto.createHash('md5').update().digest('hex');
farmhash.fingerprint64(hexDigest);

Answer 4

ES6 版本，字符串到 0-9 之间的整数：

string.split('').map(i => i.charCodeAt(0)).reduce((a, b) => a + b, 0) % 10
