Password Encryption

Encrypt Password in MD5,SHA,SHA-256 Format

if you want to encrypt password in different different format just you need to change accordingly in MessageDigest.getInstance('here is your Encryption Algorithm')

public String encryptPassword(){




   MessageDigest md = MessageDigest.getInstance("MD5");

   FileOutputStream fio = new FileOutputStream("c:\\loging.log");

   fio.write(password.getBytes());

   fio.close();

   FileInputStream fis = new FileInputStream("c:\\loging.log");



   byte[] dataBytes = new byte[1024];



   int nread = 0;

   while ((nread = fis.read(dataBytes)) != -1) {

    md.update(dataBytes, 0, nread);

   }

   ;

   byte[] mdbytes = md.digest();



   // convert the byte to hex format method 1

   StringBuffer sb = new StringBuffer();

   for (int i = 0; i < mdbytes.length; i++) {

    sb.append(Integer.toString((mdbytes[i] & 0xff) + 0x100, 16)

      .substring(1));

   }



   fio.close();

   System.out.println(sb.toString());

                        return sb.toString();



 }
