Password Encryption

Password Encryption java example.

package hash;

import java.security.*;

public class Encryption {

    public static String md5(String plainText) {

        String encryptedText = "";
        try {
            MessageDigest md = MessageDigest.getInstance("MD5");
            byte[] encryptedData = md.digest(plainText.getBytes());
            encryptedText = new String(encryptedData);

        } catch (NoSuchAlgorithmException ex) {
        }
        return encryptedText;

    }
}

package hash;
public class Main {
    public static void main(String[] args) {
        System.out.println(Encryption.md5("123"));
    }
}
