Note that there are some pretty significant caveats to Secretive:
- You cannot import your existing SSH keys
- You cannot transfer SSH keys if you get a new machine
- You cannot import your existing SSH keys
- You cannot transfer SSH keys if you get a new machine
BTW, if you have a key that you copy around to multiple machines, you’re doing it wrong!
With some security mechanism, I'd consider:
1. prevent other people from being able to use it. 2. recover from it in case it gets lost.
If your perspective is "if I lose this laptop, I have some other way to access the systems", then it's good to never access the SSH key secret.
If your perspective is that you want your secret key to be the only way to access some system, you'll want to have some way to recover the secret.
I think in any case, it's understood that having an unrecoverable secret being the only way to access some system is a bad idea.
If there is some sort of use case where I want to be able to backup a key, or share it with someone else I can always fall back to SSH keys on a hard disk. But those are usually anti-patterns.
I might also be ok if somebody like Apple had engineered a cloud solution for securely keeping backups, but only maybe.
