Question

我有一个哈希的Wordpress密码数据库。我试图根据数据库存储的密码检查用户的密码，但哈希值不正确。我在isMatch()中使用this github code进行了一些登录。任何想法为什么这些密码不匹配？纯文本密码为alberta10

  public boolean isMatch(String password, String storedHash) {
    // The first 12 digits of the hash is used to modify the encryption.
    String setting = storedHash.substring(0, 12);
    logger.log(Level.INFO, "----Hashed pwd from db is: "+storedHash);
    logger.log(Level.INFO, "----Hashed pwd using php-pass: "+encrypt(password, setting));

    return storedHash.equals(encrypt(password, setting));
  }

这是我的authenticate()方法

private void authenticate(String username, String password) throws Exception {
    // Throw an Exception if the credentials are invalid
    PasswordHasher pwdHasher=new PasswordHasher();

    _logger.log(Level.INFO, "----Authenticating user: "+username);
    try{
    Connection conn=authenticationBiz.connWordpressDB();
    String query = "SELECT * FROM wp_users WHERE user_login = ?";
    PreparedStatement preparedStmt = conn.prepareStatement(query);
    preparedStmt.setString(1, username);
    ResultSet rs=preparedStmt.executeQuery();
    rs.next();//get first result
    _logger.log(Level.INFO, "----Hashed pwd from db is: "+rs.getString("user_pass"));
    if(pwdHasher.isMatch(password,rs.getString("user_pass")))            
        return;
    }
    catch(Exception e){
        _logger.log(Level.INFO, "----Exception in Authenticating user: "+e);            
        throw e;
    }
    throw new Exception();
}

继承日志输出：

----Hashed pwd from db is: $P$BeatnTVG2/U8KZwpaWbPUF4yghHEKf.
    17:21:40,997 INFO  [com.mollom.phpass] (default task-37) ----Hashed pwd from db is: $P$BeatnTVG2/U8KZwpaWbPUF4yghHEKf.
 ----Hashed pwd using php-pass: $P$BeatnTVG2etvrth3rlCUdiNRm93PO9xZjXNr1f5s8izUZFfIq70V

Answer 1

原来我使用的Github项目与用于生成哈希的初始标准不匹配。我发现：https://github.com/Wolf480pl/PHPass完美无缺

Answer 2

Wordpress使用8次哈希迭代，你链接的git hub cod使用了15次迭代，也许你不能尝试减少常量HASH_ITERATIONS中定义的哈希迭代次数。

尝试使用phpass检查wordpress密码哈希
