    /** 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)
