A private key everyone can read

Your SSH private key ~/.ssh/id_rsa is world-readable (rw-r--r--). SSH will refuse to use it, and it's a real security risk. Tighten it so only you can read it.

Your mission

Set `~/.ssh/id_rsa` to mode 600 (owner read/write only)

Everything here is simulated and safe — break things freely. Your progress is tracked on the right and saved in this browser.
