reply in gmail does not decrypt

Is there a way to decrypt the message when replying.

i.e. I get an encrypted mail, it auto decrypts it.  Then I hit reply or forward and the message inline is the encrypted messages with a bunch of >'s down the left side.  So they get my reply and then a bunch of encrypted nonsense (representing the previous correspondence) below.

Can the response be decrypted and then be re-encrypted when I send?

I hope I am clear.

Thanks!
