Why this tool?

Malware regularly uses USB sticks to infect victims. This solution can convert documents with potentially harmful code into disarmed data formats. This converted data is then stored on a trusted device.

How it works

The code runs on a Raspberry Pi. Therefore it is not required to plug the original USB drive into a computer. By forming an air gap your normal computer system does not have to touch the possibly harmful stick or drive.

Usage and audience

CIRCLean is commonly used for data sanitizing or data transfers. Target users for this tool are general public.
