Porotokole hamwe nibyabaye

Ibyo Nymchat mubyukuri ashyira kumurongo, kubantu bose bubaka, kugenzura, cyangwa gusoma ibyabaye kubandi bakiriya ba Nostr.

Uru rupapuro rwahinduwe imashini kugirango byorohe. Umwimerere wicyongereza ni verisiyo ikoreshwa.

Ubwoko bwibyabaye

Ineza	Byakoreshejwe Kuri	Inyandiko
`0`	Umwirondoro wa metadata	Umwirondoro usanzwe wa Nostr: izina, ishusho, banneri, hafi, `lud16`.
`5`	Gusiba	NIP-09.
`7`	Ibisubizo	NIP-25, hamwe na `['k', originalKind]` tagi rero reaction yatanzwe muburyo bwumurongo wiburyo.
`13`	Ikirango	Igice cyo hagati cyubutumwa bwa NIP-17.
`14`	Ubutumwa bwihariye	Bidashyizweho umukono, kandi ntabwo bigeze bisohoka wenyine.
`1059`	Impano	NIP-59. Niki mubyukuri bigera kumurongo wubutumwa bwihariye no kuganira mumatsinda.

`30078`	Ibyatanzwe	NIP-78. Amatora, hamwe na encrypted igenamiterere sync.
`69420`	Wenyine usome inyemezabwishyu hamwe nuburyo bwo gutanga	Nymchat-yihariye, itwarwa nkibihuha imbere yimpano. Ubwoko butandukanye na `14` nkana, bityo abandi bakiriya ba NIP-17 ntibatanga ubutumwa butaziguye kuri buri nyemezabuguzi.

NIPs Nymchat

NIP	Ibyo biha Nymchat
NIP-07	Injira hamwe niyagurwa rya mushakisha.
NIP-09	Gusiba.
NIP-13	Icyemezo cy'akazi. Ubutumwa busohoka bwacukuwe byibuze 16 bits.
NIP-17	Ubutumwa bwihariye butaziguye, hamwe nifatiro ryo kuganira mumatsinda.
NIP-25	Ibisubizo.
NIP-30	Emoji.
NIP-40	Igihe kirangirire - ubutumwa bubura.

Cryptography

Aho	Niki
Indangamuntu n'umukono	secp256k1 hamwe na Schnorr umukono (BIP-340), nkuko Nostr abisobanura.
Ubutumwa bwihariye no kuganira mumatsinda	NIP-44 v2: ECDH kuri secp256k1, HKDF-SHA256, ChaCha20 hamwe na HMAC-SHA256, hamwe na padi kuburyo uburebure bwa ciphertext budatanga ubutumwa burebure.
Mesh yamashanyarazi	Urusaku XX - X25519, ChaCha20-Poly1305 (IETF), Ed25519 yo gutangaza imikono, SHA-256 na HMAC munsi.
Indangamuntu mu kiruhuko	AES-GCM-256. Urufunguzo ruva muri PBKDF2-SHA256 kuri 310.000 yogusubiramo ijambo ryibanga cyangwa PIN, cyangwa biva muri WebAuthn PRF isohoka binyuze muri HKDF-SHA256 kuri passkey cyangwa biometric.
Hamagara no kohereza dosiye	WebRTC yonyine DTLS-SRTP, yumvikanye kuri NIP-17 yerekana ibimenyetso.
Ubusanzwe	Ihuriro CSPRNG muri rusange - urufunguzo, nonces, hamwe nimpano-gupfunyika timestamp jitter.

Kurinda Metadata

Ibisobanuro bibiri munzira-gupfunyika inzira ikwiye guhamagarwa, kuko aribyo bitandukanye NIP-59 Kuva "gushishoza, ariko biragaragara ko biva kuri wewe":

Igipfunyika cyose cyashyizweho umukono na a urufunguzo rimwe byakozwe kuri ubwo butumwa bwonyine, ntamuzingo ibiri rero ugabana uwagutumye.
Igipfunyika cyose created_at ni ku buryo budasubirwaho inyuma kugeza kuri ebyiri amasaha ukoresheje CSPRNG, ohereza kandi wakire ibihe ntibishobora gutondekwa.

Amatsinda yo kuganira yongeraho kuzunguruka uwahawe urufunguzo hejuru yibyo - reba Uburyo itsinda ryibanga rikora.
