reading input from array and saving output to database md5 algorithm

[avinash4m]

I'm working on a project, and I need to run MD5 algorithm to generate a hex code. for that purpose i need to take different input everytime, my md5 algorithm is below....

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class MD5Test
{
public static void main(String[] args)
{
String md5val = "12";
MessageDigest algorithm = null;

try
{
algorithm = MessageDigest.getInstance("MD5");
}
catch (NoSuchAlgorithmException nsae)
{
System.out.println("Cannot find digest algorithm");
System.exit(1);
}

for (String arg : args)
{
byte[] defaultBytes = arg.getBytes();
algorithm.reset();
algorithm.update(defaultBytes);
byte messageDigest[] = algorithm.digest();
StringBuffer hexString = new StringBuffer();

for (int i = 0; i < messageDigest.length; i++)
{
String hex = Integer.toHexString(0xFF & messageDigest[i]);
if (hex.length() == 1)
{
hexString.append('0');
}
hexString.append(hex);
}
md5val = hexString.toString();
System.out.println(""+ md5val);
}
}
}


1) the input should be random, it should be not taken from console.. we need to use some array or Random() class for taking input.

2) the output should be stored in the database... suppose in a field called password.


can u please help me...


thanking you...

what data base are you using?

....

if its mysql try reading this:

Java Tips - How to connect MySql Server using JDBC

and you said that it should be a random number try using math.random

java tip Math.random
