Omusingi gw’okumanya Wansi wa hood

Protocol n'ebibaddewo

Nymchat ky’eteeka mu butuufu ku waya, eri omuntu yenna azimba ku yo, okugibala, oba okusoma ebibaddewo okuva ku kasitoma wa Nostr omulala.

Omuko guno guvvuunuddwa mu kyuma okusobola okugunguyira. Enkyusa y’Olungereza original y’enkyusa ekwata ku nsonga eno.

Ebika by’emikolo

Kisa	Ekozesebwa ku...	Ebiwandiiko

`7`	Ebikolwa eby’okuddamu	NIP-25, nga kuliko a `['k', originalKind]` tag kale reaction eteekebwa mu fayiro ku kika ky’omukutu ekituufu.
`13`	Okusiba	Layer eya wakati ey'obubaka bwa NIP-17.
`14`	Olugambo lw'obubaka obw'ekyama	Tekirina mukono, era tekifulumizibwangako ku bwayo.
`1059`	Okuzinga ebirabo	NIP-59. Ekituufu ekituuka ku relay for private messages ne group chats.

`20000`	Obubaka bw'omukutu gwa Geohash	Ephemeral, eriko akabonero `['g', geohash]`.
`23333`	Obubaka bw'omukutu ogutuumiddwa erinnya	Ephemeral, eriko akabonero `['d', channel]`.
`24420` / `24421`	Ebiraga okuwandiika mu lujjudde n’okusoma lisiiti	Nymchat-specific, ku mikutu egy'olukale.
`25051` / `25052`	Okulaga obubonero okuva ku bannaabwe n’embeera y’okutambuza fayiro	Nymchat-ekwata ku nsonga eno.
`30030`	Ebintu ebikozesebwa mu emoji	NIP-30.
`30078`	Data y’okukozesa	NIP-78. Okulonda, n'ensengeka ezikubiddwa ensirifu bikwatagana.
`69420`	Lisiiti z’okusoma ez’obwannannyini n’embeera y’okutuusa	Nymchat-specific, etambuzibwa nga olugambo munda mu gift wrap. Ekika eky’enjawulo okuva ku `14` mu bugenderevu, kale bakasitoma abalala aba NIP-17 tebakola bubaka butereevu bwereere ku buli lisiiti.

NIPs Nymchat essa mu nkola

NIP	Bye kiwa Nymchat
NIP-07	Yingira n'ekyongerwako kya browser.
NIP-09	Okusaba okusazaamu.
NIP-13	Obukakafu bw’omulimu. Obubaka obufuluma busimibwa okutuuka ku bits ezitakka wansi wa 16.
NIP-17	Obubaka obw’obwannannyini obutereevu, n’omusingi gw’okukubaganya ebirowoozo mu bibinja.
NIP-25	Ebikolwa eby’okuddamu.
NIP-30	Emoji eza bulijjo.
NIP-40	Ebiseera ebiggwaako — obubaka obubula.
NIP-44	Ensirifu eriko enkyusa, ekozesebwa okusiba, okuzinga n'okukwataganya ensengeka.
NIP-46	Okussa omukono okuva ewala — `bunker://`.
NIP-56	Okukola lipoota.
NIP-57	Omulabe gwa zaps.
NIP-59	Ebirabo ebizinga.
NIP-78	Data y’okusaba mu ngeri ey’ekimpatiira.
NIP-98	HTTP auth, ku nkomerero ezikyaza.

Okuwandiika mu ngeri ey’ekikugu (Cryptography).

Wa	Kiki
Endagamuntu n’emikono	secp256k1 n'emikono gya Schnorr (BIP-340), nga Nostr bw'elaga.
Obubaka obw’ekyama n’okunyumya mu bibinja	NIP-44 v2: ECDH ku secp256k1, HKDF-SHA256, ChaCha20 ne HMAC-SHA256, ne padding kale obuwanvu bwa ciphertext tebuwa buwanvu bwa bubaka wala.
Entuula za Bluetooth mesh	Noise XX — X25519, ChaCha20-Poly1305 (IETF), Ed25519 ku mikono gy’okulangirira, SHA-256 ne HMAC wansi.
Endagamuntu mu kuwummula	AES-GCM-256. Ekisumuluzo kiva mu PBKDF2-SHA256 ku 310,000 iterations ku password oba PIN, oba okuva mu WebAuthn PRF output okuyita mu HKDF-SHA256 ku passkey oba biometric.
Okukuba essimu n’okutambuza fayiro	WebRTC yennyini DTLS-SRTP, yateesa ku NIP-17-wrapped signalling.
Okubeera mu ngeri ey’ekifuulannenge	Omukutu CSPRNG wonna — ebisumuluzo, nonces, n'ekirabo-okuzinga timestamp jitter.

Okukuuma metadata

Ebintu bibiri mu kkubo ly’okuzinga ebirabo bisaana okuyitibwa, kubanga bye byawula NIP-59 okuva ku "encrypted, naye nga kirabika okuva gy'oli okutuuka ku bo":

Buli wrap eteekebwako omukono gwa a ekisumuluzo eky’omulundi gumu ekoleddwa olw’obubaka obwo bwokka, . kale tewali wraps bbiri zigabana musindika.
Buli wrap's created_at -li randomly backdated okutuuka ku babiri essaawa nga okozesa CSPRNG, kale ebiseera by'okusindika n'okufuna tebisobola kuteekebwa mu layini.

Enjogera mu bibinja zongera ku bikyukakyuka ebikyukakyuka oyo afuna obuyambi ebisumuluzo waggulu w’ekyo — laba Engeri ensirifu y’ekibiina gye ekola.

Okusoma ensonda

Aba crypto primitives bali mu js/nym-crypto.js ne js/modules/key-vault.js mu web app, ne wansi android-ios-app/lib/core/crypto/ ne lib/services/mesh/noise/ mu pulogulaamu ya Flutter. Omu etterekero ly’ebintu ye AGPL-3.0 era ewedde — tewali kitundu kiggaddwa okutwala obwesige.
