pub type NodeId = PublicKey;Available on crate feature 
key only.Expand description
The identifier for a node in the (iroh) network.
Each node in iroh has a unique identifier created as a cryptographic key. This can be used to globally identify a node. Since it is also a cryptographic key it is also the mechanism by which all traffic is always encrypted for a specific node only.
This is equivalent to PublicKey.  By convention we will (or should) use PublicKey
as type name when performing cryptographic operations, but use NodeId when referencing
a node.  E.g.:
encrypt(key: PublicKey)send_to(node: NodeId)

struct NodeId(/* private fields */);
