Packages that use PublicKey
Package
Description
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.
Core cryptographic primitives used throughout I2P: symmetric ciphers (AES, ChaCha20), hashes (SHA-1, SHA-256, SHA-384, SHA-512), HMAC and HKDF key derivation, the ElGamal and DSA/EdDSA/RedDSA engines, key and certificate utilities, and the entropy harvester.
X25519 elliptic curve Diffie-Hellman key exchange (RFC 7748), wrapping Noise's Curve25519 operations with Java Security API parameter specifications.
Common data structures used by the I2P protocols: Destination, LeaseSet, PublicKey, Signature, Certificate and their friends.
Low-level messages sent between routers - the Invisible Internet Network Protocol (I2NP).
The I2P router application handles I2P network communication.
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.
The I2P startup package loads configuration when I2P is started.
Tunnel pool management: pool lifecycle, peer selection, build scheduling and failure handling for client and exploratory tunnels.
