我试图在路由器登录页面上模拟登录功能。该函数与一些实用程序JS脚本一起包含在登录页面上。每次加载页面时,都会包含一个新的salt,并根据输入的密码和选定的用户生成一个哈希(只有两种可能)

以下是JavaScript登录函数:

function send_login() {
                var salt = "8106037b";
                var password = "";
                if (graphic_auth == "false") {
                    password = document.forms.myform.old_password.value.substr(0, 16);
                    document.forms.myform.old_password.value = "";
                    // Make sure password never gets sent as clear text
                } else {
                    password = document.forms.myform.new_password.value.substr(0, 16);
                    document.forms.myform.new_password.value = "";
                    // Make sure password never gets sent as clear text
                }
                for (var i = password.length; i < 16; i++) {
                    password += String.fromCharCode(1); // String.fromCharCode(1) = A
                }
                var input = salt + password;
                for (var i = input.length; i < 63; i++) {
                    input += String.fromCharCode(1);
                }
                if (graphic_auth == "false") {
                    input += (document.forms.myform.old_username.value == 'user') ? 'U' : String.fromCharCode(1);
                } else {
                    input += (document.forms.myform.new_username.value == 'user') ? 'U' : String.fromCharCode(1);
                }
                var hash = hex_md5(input);
                var login_hash = salt.concat(hash);
            }
函数send\u login(){
var salt=“8106037b”;
var password=“”;
如果(图形验证==“假”){
password=document.forms.myform.old_password.value.substr(0,16);
document.forms.myform.old_password.value=“”;
//确保密码永远不会以明文形式发送
}否则{
password=document.forms.myform.new_password.value.substr(0,16);
document.forms.myform.new_password.value=“”;
//确保密码永远不会以明文形式发送
}
for(var i=password.length;i<16;i++){
密码+=String.fromCharCode(1);//String.fromCharCode(1)=A
}
var输入=salt+密码;
for(var i=input.length;i<63;i++){
输入+=String.fromCharCode(1);
}
如果(图形验证==“假”){
输入+=(document.forms.myform.old_username.value=='user')?'U':String.fromCharCode(1);
}否则{
输入+=(document.forms.myform.new_username.value=='user')?'U':String.fromCharCode(1);
}
var hash=hex_md5(输入);
var login_hash=salt.concat(散列);
}
这是我用Java复制它的尝试:

public static void main(String [] args) {
    engine = new ScriptEngineManager().getEngineByName("nashorn");
    try {
        engine.eval(new FileReader("C:/Users/xx/Documents/Fiddler2/Captures/md5.js"));
    } catch (Exception e) {
        e.printStackTrace();
    } 

    invocable = (Invocable) engine;

    System.out.print(generateLoginHash("8106037b", ""));
}

public static String generateLoginHash(String salt, String password) {
    for (int i = password.length(); i < 16; i++) {
        password += "A";
    }
    String input = salt+password;
    for (int i = input.length(); i < 63; i++) {
        input += "A";
    }
    // input += (document.forms.myform.old_username.value == 'user') ? 'U' : String.fromCharCode(1);
    input += "U";
    System.out.print(input + "\n");
    String hash = hash(input);
    String login_hash = salt + hash;
    return login_hash;
}

public static String hash(String input) {
    Object result = null;
    try {
        result = invocable.invokeFunction("hex_md5", input);
    } catch (ScriptException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
    return result.toString();
}
publicstaticvoidmain(字符串[]args){
engine=new ScriptEngineManager().getEngineByName(“nashorn”);
试一试{
eval(新的文件阅读器(“C:/Users/xx/Documents/Fiddler2/Captures/md5.js”);
}捕获(例外e){
e、 printStackTrace();
} 
invocable=(invocable)引擎;
系统输出打印(generateLoginHash(“8106037b”);
}
公共静态字符串generateLoginHash(字符串salt、字符串密码){
for(int i=password.length();i<16;i++){
密码+=“A”;
}
字符串输入=salt+密码;
for(int i=input.length();i<63;i++){
输入+=“A”;
}
//输入+=(document.forms.myform.old_username.value=='user')?'U':String.fromCharCode(1);

系统输出打印(输入+“\n”);

}

}捕获(脚本异常){

}捕获(无此方法例外){
e、 printStackTrace();
}
返回result.toString();
}
如您所见,我使用的JSMD5实现与登录页面使用的实现相同(下载并保存)

但是,我生成的登录哈希与登录脚本生成的实际哈希不匹配

例如,使用用户“User”、空白密码和salt 8106037b登录时,应生成哈希:8106037bb70f15dcbd74fd1a7b14df4f54483863,但我的不匹配

我错过了什么
