i had to transfer an image over network. i thought to first encrypt it.
at sender i am using:

Image image;//
Cipher c=Cipher.gentIstance("DES/CBC/KCS5padding");
SealedObject so=new SealedObject(i,c);
out.writeObject(so);//out is objectoutputstream object

at reciever:

Image image;
Cipher c=Cipher.gentIstance("DES/CBC/KCS5padding");
if((c=(Cipher)in.readObject())!=null){ //in is objectinputstream
object
image=((Image)so.getObject(c));//

}


i knows i am wrong somewhere but i actually don't understand how to use
crypto package plz help and send me correct code

The object written to the input stream is a SealedObject. It clearly won't be a Cipher when you try to read it back.
