bcrypt.CompareHashAndPassword what crypt type use code example

Example 1: how to hash password in node js

npm i bcrypt

const bcrypt = require('bcrypt');
async function hashIt(password){
  const salt = await bcrypt.genSalt(6);
  const hashed = await bcrypt.hash(password, salt);
}
hashIt(password);
// compare the password user entered with hashed pass.
async function compareIt(password){
  const validPassword = await bcrypt.compare(password, hashedPassword);
}
compareIt(password);

Example 2: bcrypt compare hash and password

var bcrypt = dcodeIO.bcrypt; 

    /** One way, can't decrypt but can compare */
    var salt = bcrypt.genSaltSync(10);

    /** Encrypt password */
    bcrypt.hash('anypassword', salt, (err, res) => {
        console.log('hash', res)
        hash = res
        compare(hash)
    });

    /** Compare stored password with new encrypted password */
    function compare(encrypted) {
        bcrypt.compare('aboveusedpassword', encrypted, (err, res) => {
            // res == true or res == false
            console.log('Compared result', res, hash) 
        })
    }

// If u want do the same with NodeJS use this:
/*		var bcrypt = require('bcryptjs')	*/
