Software to backup data and encrypt it too, that let me decrypt it on both Mac and PC?

I have a mixed network; which means that I have Win and OSX machines.

I have a ton of DVD and blu ray disks that I would like to use, to backup some of our data from long time ago; and since it is not that much; I don't want to waste a drive just for that.

Is there a utility that burn disks and does encryption on the data; but that allow me to mount the disk and decrypt it on both Windows OS and OSX?

Both OSX and Win uses their own encryption mumbo-jumbo, and I don't want to go with either solution, just in case that I can always access this data.

Just using native encryption for each system; I made 2 copy of the data. Problem solved.
