I'm migrating to a new Macbook. On my old one, I generated an ssh key pair many years ago, and I have configured that key on several sites, some of which I don't have direct control over. After I set up my keypair, I used
ssh-add to import the cert into my keychain so I wouldn't have to type the passphrase every time. This worked fine.
Now that I am migrating to a new Mac, I am trying to import my id_rsa key on my new mac, but it's asking me for a passphrase that I apparently do not remember. I feel like that passphrase must be stored in the keychain of my old mac (which I still have), but I haven't figured out which of the entries in my old keychain is my id_rsa cert (we use S/MIME encrypted e-mail at work and the cert expire frequently, so I have quite a few certs in there).
So -- is there a way for me to either view the passphrase of my id_rsa cert in Keychain Access (after I unlock it with my system password), or to export my keypair from Keychain access in such a way that I can import it on my new Mac without having the original passphrase?
