Encryption and Decryption of Image
Step 1 Create a folder and add the images in it which you want to decrypt
Step 2 Below is the code for Encryption and Decryption of the image.We have used DES encryption scheme
Note:It is recommended to first try it yourself ,then, see the code
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.security.InvalidKeyException;
import java.security.Key;
import javax.crypto.KeyGenerator;
import javax.crypto.NoSuchPaddingException;
import java.security.NoSuchAlgorithmException;
import javax.crypto.Cipher;
import javax.crypto.CipherInputStream;
public class Myclass {
public static void encryption()
throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException
{
try
{
Cipher cipher=Cipher.getInstance("DES");
KeyGenerator keyg=KeyGenerator.getInstance("DES");
Key key=keyg.generateKey();
cipher.init(Cipher.ENCRYPT_MODE, key);
CipherInputStream cipt=new CipherInputStream(new FileInputStream(new File("D:\\ID.png")), cipher);
FileOutputStream fileip=new FileOutputStream(new File("D:\\ID.png"));
int i;
while((i=cipt.read())!=-1)
{
fileip.write(i);
}
cipher.init(Cipher.DECRYPT_MODE, key);
CipherInputStream ciptt=new CipherInputStream(new FileInputStream(new File("D:\\ID.png")), cipher);
FileOutputStream fileop=new FileOutputStream(new File("D:\\ID.png"));
int j;
while((j=ciptt.read())!=-1)
{
fileop.write(j);
}
}
catch(Exception e)
{
e.printStackTrace();
public static void main(String[] args)
{
try
{
Myclass.encryption();
}catch(Exception e)
{
e.printStackTrace();
}
}
}
