shiro 加密登录 密码加盐处理

public static final String md5(String password, String salt){
    //加密方式
    String hashAlgorithmName = "MD5";
    //盐：为了即使相同的密码不同的盐加密后的结果也不同
    ByteSource byteSalt = ByteSource.Util.bytes(salt);
    //密码
    Object source = password;
    //加密次数
    int hashIterations = ;
    SimpleHash result = new SimpleHash(hashAlgorithmName, source, byteSalt, hashIterations);
    return result.toString();
}

public static void main(String[] args) {
    String password = md5("123456", "WHLH");
    System.out.println(password);
    //加密后的结果
