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	Aan saxiixin, oo aan waligeed la daabicin kaligiis.
`1059`	Duub hadiyadeed	NIP-59. Maxaa dhab ahaantii gaadhay gudbinta fariimaha gaarka ah iyo wada sheekaysiga kooxeed.
`1984`	Ka warbixinta	NIP-56.
`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]`.
`23333`	Fariinta kanaalka loo magacaabay	Ephemeral, calaamadeysan `['d', channel]`.
`24420` / `24421`	Tilmaamayaasha daabacaadda dadweynaha iyo akhrinta rasiidhada	Nymchat-gaar ah, oo loogu talagalay kanaalada dadweynaha.
`25051` / `25052`	Calaamadaynta fac-ilaa-fac iyo heerka wareejinta faylka	Nymchat-gaar ah.
`30030`	Hababka Emoji ee gaarka ah	NIP-30.
`30078`	Xogta codsiga	NIP-78. Codbixinta, iyo habayn sir ah ayaa wada socda.
`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.

NIPs Nymchat waxay fulisaa

NIP	Waxa ay siinaysaa Nymchat
NIP-07	Ku soo gal kordhin browser

NIP-13	Caddeynta shaqada. Farriimaha baxaya waxa lagu miinadaa ugu yaraan 16 bits.
NIP-17	Fariimaha tooska ah ee gaarka ah, iyo saldhigga wada sheekaysiga kooxeed.
NIP-25	Falcelinta
NIP-30	Emoji gaar ah
NIP-40	Waqtiyada dhicitaanka - fariimaha lumaya.
NIP-44	Sirin qaabaysan, oo loo isticmaalo shaabadaynta, duubista iyo isku xidhka dejinta
NIP-46	Saxeexa fog - `bunker://`.
NIP-56	Ka warbixinta
NIP-57	hillaaca.
NIP-59	Duubista hadiyadda.
NIP-78	Xogta codsiga aan sabab lahayn.
NIP-98	HTTP auth, ee meelaha dhamaadka la marti galiyay.

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.
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 ee u gaarka ah DTLS-SRTP, ayaa ka gorgortamay NIP-17-ku-duuban signaling.
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.

Sheeko-kooxeedyadu waxay ku daraan ephemeral wareeg ah qaataha furayaasha kor ku xusan - eeg Sida sirta kooxdu u shaqeyso.

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.
