As always, thank you for educating those of us who are newbies!!!
I thought the data in an encrypted disc image stays encrypted, and is only decrypted when it is copied out of the image. I've used some very large encrypted images, and to decrypt 20-30GB of data would take an age upon mounting if the entire image was then decrypted.
