Hello @vatsa287 , The PeerId is created when node_id is converted into byte vector which is later passed in generate_peer_id function which encodes it in UTF8 and decodes it in BASE58 and the decoded variable is wrapped in a struct .
If I have understood it correctly , can you please give me a hint as to how to generate a peer_id greater than MAX_PEER_ID_LENGTH but also keep the node_id less than the MAX_NODE_ID_LENGTH

@zeel991
From my understanding it is not possible to test it by calling the method itself. Instead test for generate_peer_id itself. Check if the produced output is greater than allowed length for a peer id.
The upper bound constants are defined in mock.rs for test usage.
