I have a new computer with a shiny slot for an SD card. I have brought a nice fast 32GB SD card for it and will be using that as personal back up of my important documents.
What I hope to be able to do is create some sort of "service" that will encrypt the files and then copy them to the SD card.
What free software can I get that will encrypt the files (I need to use some of the standard encryption algorithms – AES type for the encryption) and what can I use to create the service?
I am running a Windows 7 64 bit Professional Edition, so Bitlocker is unavailable.
