Hacking encryption into Android
Next weekend we are going to have a small hackathon in Berlin to port/fix/implement disk encryption on various Android devices. Android has full disk encryption since 4.0, but it only works when using regular filesystems, e.g. ext. If you have a device that doesn’t offer proper block devices, because the hardware doesn’t do wear-leveling et cetera, you will probably have YAFFS2 as a file system or something similar that does this on software side.
