Functions ¶
func PrivateForNode ¶
func PrivateForNode(k key.NodePrivate) key.DiscoPrivate
PrivateForNode derives a node's disco private key from its node private key: HMAC-SHA256 under a headwire-specific domain, clamped as a Curve25519 scalar. The disco public key is therefore a fixed function of the node identity and can be pasted into peers' configs next to the public key. Only that public half is exposed, but it travels in cleartext in every disco frame on direct paths and never changes, so it identifies the node to a passive observer.
func PublicForNode ¶
func PublicForNode(k key.NodePrivate) key.DiscoPublic
PublicForNode returns the disco public key peers must configure for the node with private key k.
