Bug: raw ed25519.PublicKey bytes were stored directly instead of
OpenSSH authorized-key format (ssh-ed25519 AAAA... label).
Fixes:
- internal/sshmanager/fingerprint.go: GenerateKeyPair now uses
ssh.NewPublicKey + ssh.MarshalAuthorizedKey
- internal/sshmanager/keys.go: EnsureServerKey uses same fix; also
regenerates .pub file from private key if stored value is corrupt
- internal/sshmanager/fingerprint.go: add MarshalED25519PublicKey,
PublicKeyFromPrivateKeyFile, RegeneratePublicKeyFromPrivateKeyFile
- internal/models/sshkey.go: add UpdatePublicKey
- internal/api/handlers_sshkeys.go: List+Get recover existing DB
records with corrupt public keys by regenerating from private key
file and updating the DB
Also adds golang.org/x/crypto/ssh dependency via go mod tidy.
