Examples

Creating the Password Instance

import { Password } from '@leismore/password';

Password.create('YOUR_PLAIN_PASSWORD').then(pw => {
    // Your hashed password
    console.log(pw.hashed);
}).catch(e => {
    console.log(e);
});

Password Verification

import { Password } from '@leismore/password';

Password.create('YOUR_PLAIN_PASSWORD').then(pw => {
    return pw.verify('YOUR_PLAIN_PASSWORD');
}).then(result => {
    console.log(result); // Should be 'true'
}).catch(e => {
    console.log(e);
});

API

type Password = {
  hashed:     string,        // Hashed password
  generated:  number,        // Unix timestamp (milliseconds)
  expiry:     (number|null)  // Unix timestamp (milliseconds)
};

const SALT_ROUNDS_DEFAULT         = 10;
const PASSWORD_MIN_LENGTH_DEFAULT = 6;  // Characters
