JavaScriptでハッシュ

jsSHA
hashing

const jsSHA = require('jssha');

let shaObj = new jsSHA('SHA-256', 'TEXT');
shaObj.update('input');
let hash = shaObj.getHash('HEX');
console.log(hash);
hash = shaObj.getHash('B64');
console.log(hash);

shaObj = new jsSHA('SHA-512', 'TEXT');
shaObj.update('input');
hash = shaObj.getHash('HEX');
console.log(hash);
hash = shaObj.getHash('B64');
console.log(hash);

ハッシュアルゴリズムを変更したい場合は
アルゴリズムを再設定するメソッドが無いみたいなので
毎回newしないといけない様子。

パスワード用

node-password-hash

verify機能もある

const passwordHash = require('password-hash');

let counter = 0;
while (counter < 5) {
  var hashedPassword = passwordHash.generate(
    'password123',
    {
      algorithm: "sha256"
    }
  );
  console.log(hashedPassword);
  counter++;
}
