Mameseji epachivande

Hurukuro dzeumwe-kune-mumwe dzisingagoni kuverenga, dzakanangana nemakiyi ayo zviripo kune meseji imwe chete.

Peji ino yakaturikirwa nemuchina kuti zvirerukire. ChiRungu chepakutanga ndiyo shanduro inoshanda.

Kutanga meseji yakavanzika

Nzira nhatu:

• /pm nym, kana /pm nym#a1b2 kana vanhu vaviri vatora zvakafanana name;
• Private Mharidzo kubva pamenu yemunhu wese, yakasvikwa nekudzvanya kwenguva refu kana kubaya-kurudyi imwe yemameseji avo;
• diki + padivi peChakavanzika Messages chikamu mupadivi pebar, iyo inotora a nym kana npub.

Ndiani anobvumirwa kutanga imwe newe zviri kwauri. Gamuchira Private meseji & Group Chat Zvikumbiro, pasi Settings › Chakavanzika & Chengetedzo, inogoneswa nekusingaperi uye inogona kudaro yakamanikana kuti Shamwari chete kana kudzima zvachose.

Mameseji epachivande anoshanda sei

Nymchat zvishandiso NIP-17 zvakavanzika zvakananga mameseji, akavharirwa mukati NIP-59 chipo wraps. Mharidzo yako inopinda nepakati pezvikamu zvitatu pakubuda:

1. a makuhwa (kind 14) - zvinyorwa uye metadata yacho, hazvina kumbobvira yakasainwa, saka haingambotapurwi kuti ndeyako nemunhu asina kuinyora;
2. a chisimbiso (kind 13) - runyerekupe rwakavharirwa kune mugamuchiri uye akasainwa newe;
3. a chipo chekuputira (kind 1059) - chisimbiso chakavharidzirwa zvakare, yakasainwa na kiyi yenguva imwe chete yakagadzirwa kune iyi meseji chete.

Izvo zvinoratidzwa nerelay, saka, chiitiko kubva kune pubkey isina kumbobvira yaonekwa uye hazvizofa zvakare, zvakanyorerwa kune anogamuchira, ine opaque yemukati. Kwete kiyi yako. Kwete iyo message. Hapana kana munhu anongotumira anowirirana.

Iyo yekuputira timestamp yakashata nemaune, zvakare: inodzoserwa kumashure nehuwandu husina kurongeka hwekusvika. maawa maviri, akatorwa kubva kune cryptographic RNG. Pasina izvozvo, mucherechedzi anogona kumisa "kuputira kutumirwa na14:03:11" ne"kupeta kunopiwa na14:03:11" uye kuvakazve ndiani arikutaura kubva panguva. ndega.

Quantum resistance

Iyo encryption iri pamusoro inotsamira pane elliptic-curve kiyi shanduko ine simba rakakwana quantum komputa inogona kupaza - uye mhandu inogona kurekodha traffic nhasi kuti decrypt kamwe imwe iripo. Pakati pevashandisi veNymchat, Nymchat inogona kuwedzera yechipiri, post-quantum key exchange (ML-KEM-768) padivi peyakajairwa, saka ese ari maviri aifanira kutyorwa kuti averenge meseji.

Izvi zvinoitika zvoga pakati pevashandisi veNymchat uye hazvina mhengero yepasichingaiti. Meseji dzinotumirwa nenzira iyoyo dzinoratidza chivharo pedyo nepadhoku; idzo dzisingave nekuvhurwa kwemakumbo maviri dzinoratidza chivharo chimwe chete chakatsakatwa, kuitira kuti ugare waziva kuti uri kutarisa ipi. Vamwe vashandisi dzingasabvumirani izvi, kusanganisira Bitchat nezvimwe zvinoshandiswa zveNostr, vanoramba vachigashira NIP-17 yakajairika. Ona kuverenga chipochi kune matunhu matatu ose, uye quantum-resistant encryption nezvezvinobata nezvezvasingabati.

Pamberi zvakavanzika

Kutsanangurwa kune imwe chete musati tapinda muna zvinoitika, nekuti zita racho rinovimbisa zvakawanda pane zvazvinopa. Cryptographic forward secrecy zvinoreva kuti kiyi yakabirwa haikwanisi kuvhura mameseji akatumwa asati yabirwa, uye Nymchat haina izvozvo: NIP-44 inobva kiyi yayo kubva kune yako yekusingaperi nsec, uye nganda ye post-kwantamu kubva kune kiyi yake pachayo inochengetedzwa kwenguva refu. Zvinoitwa nekuvhura kwiri pasi pano ndezvekukumbira mapasitari (relays) kuti vabvise mharidzo mberi, izvo zvinoita kuti kuderera kwenguva kopyo inenge iripo yekuti ibirwe zvachose.

Kunyangarika PM (mberi zvakavanzika), pasi Settings › Privacy & Security, inodzimwa nekusingaperi. Kuchishandura pane inowedzera NIP-40 expiration tag kune yega yega inobuda chipo kuputira, iyo inobvunza relay uye vatengi kudzima meseji mushure menguva yaunosarudza.

Icho chikumbiro, uye chakakodzera kujeka nezve izvo zvinorevei: relay inokudza iyo inodonha chiitiko, uye relay iyo isingaiti, haiiti. Inoderedza kuti kopi inogara kwenguva yakareba sei zvivakwa zvausingadzore. Haikwanise kuregedza kutumira meseji kune mumwe munhu akatogara akazvigamuchira.

Mharidzo dzinonyangarika

Kunyangarika Mushure inoseta nguva yekupera, uye inoshanda chete apo zvakavanzika zvemberi zviripo:

Zvakasiyana, Cache PMs & Boka Chats Pamudziyo anosarudza kana decrypted kurukurirano dzinochengetwa munharaunda. Inongobatidzwa, saka nhaurirano dzinoonekwa ipapo ipapo launch. Idzime uye hapana chakanyorwa chakanyorwa kudhisiki - mameseji anotorwa uye decrypted patsva nguva imwe neimwe, inononoka uye zvinoreva chero chinhu icho marelay atove nacho yakadonha yaenda nokuda kwakowo.
