j++;
}
fout.write(b1, 0 , noOfBytes);
}
System.out.println("File copied!");

rahul69Could u tell in detail which preview are you talking about, the code seems fine, but I think, in line:
for(int i=b.length-1;i>=0;i--){ b1[j]=b;
It should be b1[j]=b[j]; -

yes you are are right
It should be b1[j]=b[j];
but still
i am not able to preview the encrypted image
