Protocol na swiendlakalo

Leswi Nymchat yi swi vekaka hakunene eka waya, eka mani na mani loyi a akaka ku lwisana na yona, . ku yi odita, kumbe ku hlaya swiendlakalo ku suka eka xitirhisiwa xin’wana xa Nostr.

Tluka leri ri hundzuluxeriwe hi muchini leswaku ri olova. Original ya Xinghezi i version leyi tirhaka.

Tinxaka ta swiendlakalo

Tintswalo	Ku tirhisiwa eka	Tinhlamuselo
`0`	Metadata ya phurofayili	Standard Nostr profile: vito, xifaniso, banner, mayelana na, . `lud16`.
`5`	Swikombelo swo susa	NIP-09.
`7`	Swiendlo swa ku angula	NIP-25, leyi nga na a `['k', originalKind]` tag so reaction yi fayeriwa ku lwisana na muxaka wa channel lowu faneleke.
`13`	Siva	Leyara ya le xikarhi ya rungula ra NIP-17.
`14`	Mahungu ya rungula ra le xihundleni	A yi sayiniwa, naswona a yi si tshama yi kandziyisiwa hi yoxe.
`1059`	Ku phutsela tinyiko	NIP-59. Leswi entiyisweni swi fikaka eka relay ya marungula ya le xihundleni na ku burisana ka ntlawa.
`1984`	Ku vika	NIP-56.
`9734` / `9735`	Xikombelo xa zap na risiti ya zap	NIP-57.
`10030`	Minxaxamelo ya tiphakiti ta emoji ta ntolovelo	NIP-30.
`20000`	Rungula ra xitichi xa Geohash	Ephemeral, leyi funghiweke `['g', geohash]`.
`23333`	Rungula ra xitichi lexi thyiweke vito	Ephemeral, leyi funghiweke `['d', channel]`.
`24420` / `24421`	Swikombiso swa ku thayipa ka mani na mani na tirhisithi to hlaya	Nymchat-specific, ya tichannel ta mani na mani.
`25051` / `25052`	Ku nyika swikombiso swa tintangha na xiyimo xa ku hundziseriwa ka fayili	Nymchat leyi kongomeke.
`30030`	Tisethi ta emoji ta ntolovelo	NIP-30.
`30078`	Data ya xitirhisiwa	NIP-78. Ti polls, na swiyimiso leswi pfaleriweke swa fambisana.
`69420`	Tirisiti to hlayiwa ta le xihundleni na xiyimo xa ku rhumeriwa	Nymchat-specific, yi rhwariwile tani hi mahungu endzeni ka xifunengeto xa nyiko. Muxaka lowu hambaneke na `14` hi vomu, leswaku tiklayenti tin’wana ta NIP-17 a ti hundziseli marungula yo kongoma lama nga riki na nchumu eka risiti yin’wana na yin’wana.

NIPs Nymchat yi tirhisa

NIP	Leswi yi swi nyikaka Nymchat
NIP-07	Nghena hi xiengetelo xa browser.
NIP-09	Swikombelo swo susa.
NIP-13	Vumbhoni bya ntirho. Mahungu lama humaka ma ceriwa ku ya eka kwalomu ka 16 wa tibiti.
NIP-17	Mahungu yo kongoma ya le xihundleni, na xisekelo xa mimbulavurisano ya ntlawa.
NIP-25	Swiendlo swa ku angula.
NIP-30	Emoji ya ntolovelo.
NIP-40	Switempe swa nkarhi wo hela — marungula lama nyamalala.
NIP-44	Versioned encryption, leyi tirhisiwaka eka ku pfalela, ku phutsela na ku fambisana ka swiyimiso.
NIP-46	Ku sayina hi le kule — . `bunker://`.
NIP-56	Ku vika.
NIP-57	Rihati ra ti zaps.
NIP-59	Swifunengeto swa tinyiko.
NIP-78	Data ya xikombelo xa ku tihlawulela.
NIP-98	HTTP auth, ya tindhawu to hetelela leti khomiweke.

Ku tsala hi ku kongoma

Kwihi	Yini
Vutivi na masayini	secp256k1 na masayini ya Schnorr (BIP-340), tanihilaha Nostr yi hlamuselaka hakona.
Mahungu ya le xihundleni na ku burisana hi ntlawa	NIP-44 v2: ECDH eka secp256k1, HKDF-SHA256, ChaCha20 na HMAC-SHA256, na ku padding leswaku ku leha ka ciphertext a ku nyiki ku leha ka rungula ekule.
Tisexini ta mesh ta Bluetooth	Mpfumawulo XX — X25519, ChaCha20-Poly1305 (IETF), Ed25519 ya masayini ya switiviso, SHA-256 na HMAC ehansi.
Vutivi loko byi wisa	AES-GCM-256. Xilotlelo xi huma eka PBKDF2-SHA256 eka 310,000 wa ku vuyeleriwa ka phaswedi kumbe PIN, kumbe ku suka eka vuhumelerisi bya WebAuthn PRF hi ku tirhisa HKDF-SHA256 eka xilotlelo xa pasi kumbe byometriki.
Tifoni na ku hundziseriwa ka tifayela	WebRTC ya DTLS-SRTP hi yoxe, leyi burisaneke hi ku nyika swikombiso leswi phutseriweke hi NIP-17.
Ku va hi xitshuketa	Pulatifomo CSPRNG hinkwako — swilotlelo, nonces, na nyiko-ku phutsela timestamp jitter.

Nsirhelelo wa metadata

Vuxokoxoko byimbirhi eka ndlela yo phutsela tinyiko byi fanele ku vitaniwa, hikuva hi byona lebyi hambanisaka NIP-59 ku suka eka "encrypted, kambe swi le rivaleni ku suka eka wena ku ya eka vona":

Xifunengeto xin’wana na xin’wana xi sayiniwa hi a xilotlelo xa nkarhi wun’we yi endleriwe rungula rero ntsena, . hikwalaho ku hava swifunengeto swimbirhi leswi avelana murhumeri.
Xifunengeto xin'wana na xin'wana xa created_at i randomly backdated hi ku fika eka timbirhi tiawara hi ku tirhisa CSPRNG, hikwalaho minkarhi yo rhumela na ku amukela a yi nge layiniwi.

Ti-chat ta ntlawa ti engetela swilo swa nkarhinyana leswi cinca-cincaka muamukeri swilotlelo ehenhla ka sweswo — vona Ndlela leyi ku fihla ka ntlawa ku tirhaka ha yona.

Ku hlaya xihlovo

Ti crypto primitives ti le ka js/nym-crypto.js na js/modules/key-vault.js eka app ya webu, na le hansi android-ios-app/lib/core/crypto/ na lib/services/mesh/noise/ eka app ya Flutter. Ku... vuhlayiselo bya swilo i AGPL-3.0 naswona yi helerile — a ku na xiphemu lexi pfalekeke xo teka ku tshemba.
