if you're referring to SSH keys, you can use something like 1Password which stores them encrypted and syncs them in the cloud, so you keep them even if you lose your laptop
I have been using AGE [0]
And I really don't like the idea of having the keys stored in the home directory in plain text.
There is also a risk of losing the keys if my laptop is damaged or gets stolen.
Is there a proper tool for storing encryption keys?
