Iyo isingazivikanwe network I2P 1.9.0 uye C++ mutengi i2pd 2.43.0 zvakaburitswa. I2P ndeye yakawanda-layer isingazivikanwe yakagoverwa network inoshanda pamusoro peiyo Internet yenguva dzose, ichishingairira kushandisa yekupedzisira-kusvika-kumagumo encryption, inovimbisa kusazivikanwa uye kuzviparadzanisa nevamwe. Iyo network inovakwa muP2P modhi uye inoumbwa nekuda kwezviwanikwa (bandwidth) zvinopihwa nevashandisi venetiweki, izvo zvinoita kuti zvikwanise kuita pasina kushandisa maseva anochengetedzwa pakati (kutaurirana mukati metiweki kunoenderana nekushandiswa kweiyo encrypted unidirectional tunnels pakati. mutori wechikamu uye vezera).
MuI2P network, unogona kusazivikanwa kugadzira mawebhusaiti nemablog, kutumira mameseji nekukurumidza uye email, kuchinjanisa mafaera uye kuronga P2P network. Kuvaka uye kushandisa zvisingazivikanwe network kune mutengi-server (mawebhusaiti, chats) uye P2P (faira kugovera, cryptocurrencies) application, I2P vatengi vanoshandiswa. Iyo yakakosha I2P mutengi yakanyorwa muJava uye inogona kumhanya pane akasiyana mapuratifomu akadai seWindows, Linux, macOS, Solaris, nezvimwe. I2pd ndeyekuzvimiririra kuita kweI2P mutengi muC ++ uye inogoverwa pasi peyakagadziridzwa BSD rezinesi.
Iyo itsva vhezheni yeI2P inopedzisa kuvandudzwa kweiyo nyowani yekufambisa protocol "SSU2", yakavakirwa paUDP uye inocherechedzwa pakuvandudza mashandiro uye chengetedzo. Miedzo yakaitwa yekutarisa SSU2 pazera uye relay side. Iyo "SSU2" protocol inogoneswa nekusarudzika muAroid uye ARM inovaka, pamwe nechikamu chidiki chema routers zvichienderana nemamwe mapuratifomu. Kuburitswa kwaNovember kunoronga kugonesa "SSU2" kune vese vashandisi. Kuitwa kweSSU2 kunotitendera kunyatso gadzirisa iyo cryptographic stack, kubvisa iyo inononoka ElGamal algorithm (yekupedzisira-kusvika-kumagumo encryption, iyo ECIES-X25519-AEAD-Ratchet musanganiswa ichashandiswa pachinzvimbo cheElGamal/AES+SessionTag. ), kuderedza pamusoro uchienzaniswa neSSU uye kunatsiridza mashandiro enharembozha.
Zvimwe zvigadziriso zvinosanganisira kuwedzerwa kwedetekitari yakafa, kuve nechokwadi chekuti ruzivo rwe router (RI, RouterInfo) runotumirwa kune vezera, uye yakagadziridzwa MTU / PMTU kubata mune yekare SSU protocol. Mu i2pd, iyo SSU2 yekufambisa yakaunzwa kune yayo yekupedzisira fomu, iyo inogoneswa nekusarudzika kune kuisirwa kutsva, uye kugona kudzima bhuku rekero kwakawedzerwa.
