I’m migrating to a new laptop for work (Mac -> Mac, both on Sonoma). To migrate my ssh keys I made a tarball of my ~/.ssh directory and copied it over to the new machine.
I went to ssh to one of my servers with my pubkey and ran into an error. It turns out that my ed25519 private key is now one byte (just an N). This happened on both my new and my old machines.
It only affected my ed25519 private key. The old rsa key is fine. I have other keys for application IDs that weren’t affected, it’s just my personal key.
Could it be a keychain issue? Part of a security policy? I’m at a loss here. Any insight would be appreciated.
