kloak-rs: alternative implementation of kloak

kloak-rs is an alternative Rust implementation of kloak.

It features many security improvements over the C codebase, including:

• Written in Rust, eliminating classes of the most common vulnerabilities.
• Makes use of libraries such as evdev to avoid having to access uinput directly.
• Delays are securely generated with a ChaCha8 CSPRNG seeded by the kernel with getrandom(2).

Prerequisites

• uinput kernel module
• Access to input devices, e.g. a user in the input group

eventcap

The eventcap tool is used to identify the device file corresponding to the keyboard device, and is typically /dev/input/event*.

Usage

Usage:
    eventcap [DEVICE]

DEVICE is the device file that eventcap reads from.

Example:
    $ eventcap /dev/input/event4
    Reading from /dev/input/event4 (AT Translated Set 2 keyboard)
    Type: MISC    Code: 4    Value: 15
    Type: KEY     Code: 15   Value: 0
