Detailed Description

peer identity lifecycle service

Author

Martin Schanzenbach

This service maintains the peer identity. On address change it generates a new identity and informs subscribed components. It also signs data with the identity on request.

LOG

#define LOG	(		kind,
			...

Function Documentation

load_ikm()

static void load_ikm ( )

static

Get the initial secret key for generating the peer id.

This is supposed to be generated at random once in the lifetime of a peer, so all generated peer ids use the same initial secret key to optain the same peer id per set of addresses.

First check whether there's already a initial secret key. If so: return it. If no initial secret key exists yet, generate at random and store it where it will be found.

Parameters

initial

secret key the memory the initial secret key can be written to.
