Method UpdateHostSigner

agent/agentssh/agentssh.go:1370–1382

UpdateHostSigner updates the host signer with a new key generated from the provided seed. If an existing host key exists with the same algorithm, it is overwritten

(seed int64)

// UpdateHostSigner updates the host signer with a new key generated from the provided seed.
// If an existing host key exists with the same algorithm, it is overwritten
func (s *Server) UpdateHostSigner(seed int64) error {
	key, err := CoderSigner(seed)
	if err != nil {
		return err
	}

	s.mu.Lock()
	defer s.mu.Unlock()

	s.srv.AddHostKey(key)

	return nil
}

// CoderSigner generates a deterministic SSH signer based on the provided seed.
// It uses RSA with a key size of 2048 bits.
