Encryption Of Connection Password

[Henryosa]

Hello, I am working on one of the application, which create a connection object to the database. For that it uses the Login and password. As the end users don't know the password and it is necessary that they don't know the password of all. So, for that I want to encrypt the password so, it is not possible to decompile the binary file. So, please help me to achieve it. It will be helpful to me.

Most Jabber clients allow you to encrypt the connection. Jabber can use two methods of encryption. The oldest is the one used by websites secure connection by SSL. The port used by the server MiNET for this type of connection is port 5223. Jabber can also use a more recent technique of encryption is encryption TLS. In this case, the port used is the same as the port for messages that are clear, the port 5222. MiNET The server supports two encryption methods. How to enable encryption depends on the software you use. However, if you encrypt your connection with SSL, make sure that the port number is 5223.

Hello, I think the code below will simply help you for encrypting the password:

import java.io. *;
Public class testing
{
    Public testing(int one)
    {
       key = one;
    }
 
    Public void encryptFile(InputFileName String, String outputFileName) throws IOException
    {       
        InputStream IStream = null;
        OutputStream oStream= null;
        try
           {
              IStream = new FileInputStream(InputFileName);
              oStream= new FileOutputStream(outputFileName);
              encryptStream(IStream, out);
 
           }
       finally
           {
             if(IStream! = null)
                IStream.close();
             if(out! = null)       
                out.close();      
           }
    }
 
    Public void encryptStream(InputStream IStream, OutputStream out) throws IOException
    {
        boolean done = false;
        while(! done)
           {
                int next = IStream.read();
                if(next == -1)
                   done = true;
               else
               {
                  byte b = (byte)next;
                  byte c = encrypt(b);
                  out.write(c);
               }
           }
    }
 
    Public byte encrypt(byte b)
    {
         return (byte)(b + key);
    }    
 
    private int key;
}

I don't think that anything than MD5 hash is better. You can simply make use of it.

import java.security .*;
  private String encryption(String pass) 
{
  byte[] UKey = pass.getBytes();
  byte[] Hash = null;
  try {
   MessageDigest Hash =.getInstance("MD5").digest(UKey);
  }
  catch (Exception e) 
{ 
   e.printStackTrace();
}
StringBuffer HashString = new StringBuffer();
for (int i =0; I <Hash.length; + + I ) 
{
String hex = Integer.toHexString(Hash[i]);
if (hex.length() == 1) 
{ 
HashString.append('0');
HashString.append(hex.charAt(hex.length()-1));
}
else 
{
HashString.append(hex.substring(hex.length()-2));
}
}
return HashString.function toString() 
{
[native code]
}
}

If you want to Encrypt application configuration file then you must make use of the Jasypt. It will help you to achieve the following:

• properties files: By making use of the EncryptableProperties class for loading, managing it, you can simply encrypt it.
• Encryption-aware Spring's : You can simply read the files with the help of it.
• Hibernate's hibernate.cfg.xml file contains the datasource parameter of the Encryption.

If you want to encrypt the password then it is needed to know the password first. If you are storing the password in your source code then it is not a good idea. Or if you are saving it in the file then also it is not a good idea. Whatever happens you will have to enter a password to your user. Otherwise it will use X.509 certificates with a private key in a key store but again you'll need a password to access the store.
