Package
Description
Web100 Network Diagnostic Tool applet behind the router console speed test.
POP3 client (RFC 1939) for SusiMail, including APOP authentication.
Internal implementation of the I2P client SDK - the client side of the Invisible Internet Client Protocol (I2CP), separating implementation from the interfaces in net.i2p.client.
Implementation of a TCP-like (reliable, authenticated, in order) set of sockets for communicating over the IP-like (unreliable, unauthenticated, unordered) I2P messages.
Authentication and authorization for the I2P Control service: token management and keystore handling.
Implementation of preconfigured tunnels for clients and servers, including special-purpose tunnels for IRC, SOCKS, HTTP and streaming.
Definition-based incoming connection filter for server tunnels, with fine-grained access control by destination.
StreamR adaptive-rate streaming tunnel: streams audio and video over a single I2P tunnel, adapting the encoder rate to the measured tunnel bandwidth.
The I2P router application handles I2P network communication.
Router-side implementation of the Invisible Internet Client Protocol (I2CP): client sessions over plain or TLS sockets, message delivery, and lease and tunnel management on behalf of clients.
Router-specific cryptography: ElGamal+AES garlic encryption (ElGamalAESEngine), session key and tag caching for repeated peer communication (TransientSessionKeyManager), router-family shared keys (FamilyKeyCrypto), and the ratchet and pqc subpackages.
The Double Ratchet with X25519 key agreement and ECIES hybrid encryption, used by the NTCP2 and SSU transports for session encryption.
Garlic message creation, parsing and handling, and the outbound message jobs: one-shot sends, source routing and delivery status handling.
The Kademlia distributed hash table (DHT) network database: lookup, store and explore jobs, the data store, the floodfill variants, and lookup throttling.
Reseeding: fetching router info lists from reseed servers, web indexes or local files, validating them (signed SU3 update files and unsigned ZIP archives) and processing them to bootstrap into the network.
Peer profiles and capacity calculation, peer test jobs, peer selection for tunnel building, and the database and tunnel history used for peer selection.
The I2P startup package loads configuration when I2P is started.
Periodic maintenance jobs: stats coalescing, cryptographic algorithm checks, liveliness marking, out-of-memory handling, thread dumps, the watchdog, graceful shutdown and soft restart, update installation, republishing and config reloading.
Transport framework: the transport lifecycle and pool management, connection handling and bandwidth throttling for the transports (NTCP2 over TCP, SSU over UDP) that carry I2P messages between routers, plus NAT traversal via UPnP and GeoIP country lookups.
NTCP2, the TCP transport: framed, ratchet-encrypted and mutually authenticated connections between routers.
SSU2, the UDP transport: datagram sessions with Holepunch peer discovery, plus the older SSU compatibility code.
Tunnel messages and the tunnel layer: the TunnelManagerFacade, tunnel build request and reply processing, and the inbound and outbound tunnel structures.
Tunnel pool management: pool lifecycle, peer selection, build scheduling and failure handling for client and exploratory tunnels.
Router-side update checking and installation: fetching update notifications, downloading and verifying updates, and staging them for the restart.
Router utility classes: CoDel active queue management, time-decaying collections, a diagnostics ring buffer, CIDR matching, and password management.
The router console user interface, implemented in routerconsole.jar, with these classes supporting the webapp in routerconsole.war.
General utility classes shared across the core libraries and the router.
I2P version of the Snark BitTorrent client, enhanced for I2P: peers are I2P destinations, torrents can be served anonymously as hidden services, and metadata carries I2P-specific comment fields.
BitTorrent distributed hash table (DHT) implementation following the Mainline protocol, for trackerless peer discovery.
