How to set different clients to use different secret authentication

hi,
How to set different clients to use different secret authentication, like freeradius.

You can implement the SecretSource interface and set it as SecretSource:

Example implementation:

type HostSecrets struct {
	Secrets map[string][]byte
}

func (s *HostSecrets) RADIUSSecret(ctx context.Context, remoteAddr net.Addr) ([]byte, error) {
	host, _, err := net.SplitHostPort(remoteAddr.String())
	if err != nil {
		return nil, err
	}
	return s.Secrets[host], nil
}

h := &HostSecrets{
	Secrets: map[string][]byte{
		"::1":       []byte(`12345`),
		"127.0.0.1": []byte(`12345`),

		"10.0.0.2": []byte(`67890`),
	},
}

It's ok, thank you.
but, whether the secret is correct or not, it will be executed 'Handler'.

Can I use network segment？
Example：

h := &HostSecrets{
	Secrets: map[string][]byte{
		"::1":       []byte(`12345`),
		"10.0.0.0/24": []byte(`67890`),
	},
}
