Ciao mj, well if the question is if it possible to decrypt a geotiff on the fly using the actual GeoTiffReader (2.3.x and above) the answer is yeah (ok, I have to check but I am pretty positive :-) ). You would have to create your own ImageInputStream outside the reader using a CypherInputStream.
However the point here is not the GeoTiffReader but how ImageIO manages stream. It has its own stack of streams implementing the ImageInputStream interface, hence the best thing to do would be writing a dedicate ImageInputStream that uses the decorator pattern (much like FilterInputStream) to decrypt the image on the fly with highest performances. Once we are there we could even do the converse that is writing an ImageOutputStream that does the opposite. If you are interested we can find a way to implement this pretty quickly. Regards, Simone.
