Password Encrypt in JavaScript and Decrypt in Java

here is the steps,

1. create two jsps. [ login.jsp, validate.jsp ]
2. create one java.
3. Add cryptojs lib [ aes.js ] in your javascript path and mentioned in login.jsp.

here is the sample code.


1. login.jsp

<%@page import="java.util.Arrays"%>
<%@page import="package.Security"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
  
<%
    session.setAttribute ( "RANDKEY", Security.generateSecret (  ) );
%>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
<script src="./js/rollups/aes.js"></script>
<script src="./js/rollups/pbkdf2.js"></script>
<script type="text/javascript">
    function convertAndSubmit()
    {
         var salt = CryptoJS.lib.WordArray.random(128/8);
        var iv = CryptoJS.lib.WordArray.random(128/8);          
        //console.log('salt  '+ salt );
        //console.log('iv  '+ iv );
        var key128Bits100Iterations = CryptoJS.PBKDF2( '<%=session.getAttribute ( "RANDKEY" ) %>', salt, { keySize: 128/32, iterations: 100 });
        //console.log( 'key128Bits100Iterations '+ key128Bits100Iterations);
        var encrypted = CryptoJS.AES.encrypt(document.login.password.value, key128Bits100Iterations, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7  });
        document.login.salt.value = salt;
        document.login.iv.value = iv;
        document.login.password.value = encrypted;
        document.login.submit();
    }
</script>
</head>
<body>
    <form action="validate.jsp" method="post" name="login" autocomplete="off">
        <p>User Name : <input type="text" name="userName"/></p>
        <p>
                       <input type="text" style="display:none;">
            Password : <input type="password" name="password"/>
        </p>
        <p>
            <input type="hidden" name="salt"/>
            <input type="hidden" name="iv"/>
            <input type="button" value="Login" onclick="javascript:convertAndSubmit()"/>
        </p>
    </form>
</body>
</html>





Insert title here




   

        User Name :

       
                      
            Password :
       

       
           
           
           
       

   


2. validate.jsp

How to setup Secure FTP server and process with Core FTP client SSL



Secure FTP Client KeyPair Generation and Connection Process:

 First Create New_Site

  Click the Advance button and select SSH option
   
1)      provide the Key file ,password and click Ok.
2)      If you don’t have the Key File ,click the button Generate Key.

  After Clicking the Generate Key button ,
 
1)      Mention the Path where the Key Pair file generated must fall.
2)      Give the Name of Private Key and Public Key file and Password.
3)      Click the OK Button .
4)      You will get the key Pair file in the Mentioned Path.

5)       Give the generated Key in the Key File and password and then Ok button.


     Give the user name and password and select the SSH /SFTP button .







  Secure FTP Server Configuration for SSH :

  In the Server Side select the Existing Domain which is already created and select the User.



  Now Click the Edit  Button,It will open the User Details Box.


  In the User Details Box ,select the Security Option
