Keylogger
Capture global keyboard events on Linux
Notes
- Only Linux based
- Need root privilages
Installation
go get github.com/MarinX/keylogger
Getting started
Finding keyboard device
There is a helper on finding the keyboard.
keyboard := keylogger.FindKeyboardDevice()
Which goes through each file device name to find keyword "keyboard"
/sys/class/input/event[0-255]/device/name
and returns the file event path if found
/dev/input/event2
If the function returns empty string, you will need to cat each device name and get the event number.
If you know already, you can easily pass it to constructor
keylogger.New("/dev/input/event2")
Getting keypress
Once the keylogger returns channel event, you can switch by event code as described in input_event.go
For start, you can listen on keyboard state change
keylogger.EvKey
Once you get desire event, there is a helper to parse code into human readable key.
event.KeyString()
NOTE
If you listen on keyboard state change, it will return double results.
This is because pressing and releasing the key are 2 different state change.
There is a helper function which you can call to see which type of state change happend
// returns true if key on keyboard is pressed
event.KeyPress()
// returns true if key on keyboard is released
event.KeyRelease()
Example
You can find a example script in example/main.go
Running tests
No magic, just run
go test -v
