Protocol iyo dhacdooyinka

Maxay Nymchat dhab ahaantii ku dhejisaa fiilada, qof kasta oo ka soo horjeeda, xisaabinta, ama akhrinta dhacdooyinka macmiilka kale ee Nostr.

Boggaan waxaa loo turjumay mashiinka si ay ugu habboonaato. Asalka Ingiriisigu waa nooca khuseeya.

Noocyada dhacdada

Naxariis	loo isticmaalo	Xusuusin
`0`	Xogta badan ee xogta	Heerka Nostr profile: magaca, sawirka, banner, ku saabsan, `lud16`.
`5`	Codsiyada tirtirka	NIP-09.
`7`	Falcelinta	NIP-25, oo leh a `['k', originalKind]` tag si falcelin looga gudbiyo nooca kanaalka saxda ah.
`13`	Shaabad	Lakabka dhexe ee fariinta NIP-17.
`14`	Xanta fariinta gaarka ah	Unsigned, and never published on its own. A thread reply carries a `['nymthread', rootId]` Tag in ka mid ah rumeeyaanka codsado, si ay u mid ah id-ka dhererka dhererka codsado.
`1059`	Duub hadiyadeed	NIP-59. Maxaa dhab ahaantii gaadhay gudbinta fariimaha gaarka ah iyo wada sheekaysiga kooxeed.

`9734` / `9735`	Codsiga Zap iyo rasiidka zap	NIP-57.
`10030`	Liisaska xirmada emoji ee gaarka ah	NIP-30.
`20000`	Fariinta kanaalka Geohash	Ephemeral, calaamadeysan `['g', geohash]`A thread reply adds a NIP-10 mark `['e', rootId, '', 'root']` Tagoo
`23333`	Fariinta kanaalka loo magacaabay	Ephemeral, calaamadeysan `['d', channel]`A thread reply adds a NIP-10 mark `['e', rootId, '', 'root']` Tagoo
`24420` / `24421`	Tilmaamayaasha daabacaadda dadweynaha iyo akhrinta rasiidhada	Nymchat-gaar ah, oo loogu talagalay kanaalada dadweynaha.

`30078`	Xogta codsiga	NIP-78. Cod-bixinta, habayn sir ah oo la mid ah, iyo ogeysiisyada muhiimka ah ee quantum-ka kadib (tagged `nym-pq`, sidda furaha dadweynaha ML-KEM-768 oo leh NIP-40 dhicis.
`69420`	Rasiidhada akhriska gaarka ah iyo heerka gaarsiinta	Nymchat-gaar ah, oo xanbaarsan sida xanta gudaha duub hadiyadeed. Nooc ka duwan `14` si ula kac ah, si macaamiisha kale ee NIP-17 aysan u gudbin fariimo toos ah oo madhan rasiidh kasta.

Cryptography

Halkee	Waa maxay
Aqoonsiga iyo saxeexyada	sep256k1 oo wata saxeexa Schnorr (BIP-340), sida Nostr u qeexayo.
Fariimaha gaarka ah iyo wada sheekaysiga kooxeed	NIP-44 v2: ECDH ee sec256k1, HKDF-SHA256, ChaCha20 oo wata HMAC-SHA256, iyo suufka si dhererka ciphertext ma siinayso dhererka fariinta.
Fariimaha gaarka ah iyo wada sheekaysiga kooxeed, ee u dhexeeya isticmaalayaasha Nymchat	NIP-44 v2 payloads ugu horeysay, xigtay in ChaCha20-Poly1305 ka mid ah ka mid ah ML-KEM-768 (FIPS 203) encapsulation through HKDF-SHA256. The encapsulation encapsulation texts and both identity keys are bound in as associated data, iyo wax soo saarka waa in la mid ah. `pq2.` Qalabka ugu horeysay ee loo yaabaa in ay ku yaalaa in ay ku yaalaa in ay ku yaalaa in ay ku yaalaa in ay ku yaalaa in ay ku yaalaa in ay ku yaalaa. sireed u adkaysta tirada.
Fadhiyada mesh Bluetooth	Buuq XX — X25519, ChaCha20-Poly1305 (IETF), Ed25519 ee ku dhawaaqida saxeexyada, SHA-256 iyo HMAC ee hoose.
Aqoonsiga nasashada	AES-GCM-256. Furuhu waxa uu ka imanayaa PBKDF2-SHA256 ee 310,000 ku celcelinta sirta ah ama PIN, ama wax soo saarka WebAuthn PRF iyada oo loo marayo HKDF-SHA256 furaha furaha ama biometric.
Wicitaannada iyo wareejinta faylka	WebRTC's DTLS-SRTP, ayaa laga gorgortamay NIP-17-ku-duubnaa calaamad muujinaysa.
Randomity	Mareegta CSPRNG oo dhan - furayaasha, nonces, iyo shaambada waqti-ku-duubka hadiyadda.

Ilaalinta metadata

Laba tafaasiil oo ku jira dariiqa hadiyad-duubka ayaa mudan in la yeedho, sababtoo ah waa waxa kala sooca NIP-59 laga bilaabo "si qarsoodi ah, laakiin si cad adiga ilaa iyaga":

Duub kasta waxaa saxiixay a fure hal mar ah loo soo saaray fariintaas oo keliya, marka laba duuban lama wadaago soo diri.
Duub kasta created_at waa si aan kala sooc lahayn dib loogu celiyay ilaa laba saacadood adoo isticmaalaya CSPRNG, markaa diritaanka iyo helitaanka wakhtiyada lama safan karo.

Akhrinta isha

Astaamaha hore ee loo yaqaan 'crypto primitives' ayaa ku jira js/nym-crypto.js iyo js/modules/key-vault.js gudaha abka webka, iyo hoos android-ios-app/lib/core/crypto/ iyo lib/services/mesh/noise/ ku jira abka Flutter. The kayd waa AGPL-3.0 oo dhamaystiran - ma jirto qayb xiran oo lagu qaato kalsoonida.
