Image Encryption Tool – Data Format

Hi Everyone!

In an earlier post I said I would explain a little about the the format used in my new data encoder and so here it is.

The images are stored in PNG, not any other type of format, because PNG supports full alpha transparency. The data is encoded by converting the text into binary data and then these are converted into pixels of colour, with the data stored in one of the 4 colour components (red, green, blue, alpha).

Certain operations are then done on this data to make it harder to recover and the remaining spaces are filled in with randomly generated pixels.
