nodejs 通过盐值密码校验 的java实现方式，只有这么多豆了

通过java来通过盐值和密码来计算校验密码，是不对的，求教错在哪里，哪位做过请指点下
nodejs的代码如下：

  //无密码的属于第三方登陆不能拿昵称登陆
                authenticate: function (plainText) {
                    return this.password&&this.salt&&this.encryptPassword(plainText, this.salt) === this.password;
                },
                encryptPassword: function (password, salt) {
                    if (!password || !salt) {
                        return '';
                    }
                    salt = new Buffer(salt, 'base64');
                    return crypto.pbkdf2Sync(password, salt, 10000, 64).toString('base64');
                },

我试验的java的代码如下

 package com.xxshow.util;

     */
    public static final int SALT_BYTE_SIZE = 32 / 2;

    /**

            throws NoSuchAlgorithmException, InvalidKeySpecException {
        // 用相同的盐值对用户输入的密码进行加密

        System.out.println("加密后:"+encryptedAttemptedPassword);
        System.out.println("base64位加密后:");
        System.out.println(Base64.encodeBase64String(fromHex(encryptedAttemptedPassword)));
        encryptedAttemptedPassword = Base64.encodeBase64String(fromHex(encryptedAttemptedPassword));

    }
