Storing SSH keys on gnome-keyring, kwallet, ibsecret or similar
I don't like my ssh keys being stored in plain sight, I also don't like having to type a passphrase to use them.
On windows, once you run ssh-add, the key is stored in a secure way and managed by some kind of session manager (source), at that point you can delete the key file and go about your life knowing that the key is safe and you won't need to type a password again.
I would like something similar on linux, like storing the key via libsecret as you do with git, so that you can access your servers without having a key in plain text.
I think it's possible to generate a key with a passphrase and have gnome-keyring or kwallet remember the passphrase, but it would be nicer to just securely store the key itself.
Unless some sandboxing or other explicit security measure is in place, any software you run typically has access to your entire home directory, including .ssh/. If any one of those was compromised somehow, they've got access to your SSH keys.
Example: there's another user with sudo access, he has access to my home folder, encrypting the drive doesn't solve anything.
Or maybe you just are not the system administrator.
It's not my usecase, but it's definitely a reasonable situation.
