Fa'avae poto I lalo o le pulou

Polokalama ma mea tutupu

O le a le mea e tuʻuina moni e Nymchat i luga o le uaea, mo soʻo se tasi e fau faasaga i ai, su'etusi, po'o le faitauina o mea na tutupu mai se isi Nostr client.

O lenei itulau ua fa'aliliuina i masini mo le fa'afaigofieina. O le ulua'i fa'a-Peretania o le fa'amatalaga lea e fa'atatau.

Cryptography

O fea	O le a
Fa'asinomaga ma saini	secp256k1 ma Schnorr saini (BIP-340), e pei ona faamaoti mai e Nostr.
O fe'au patino ma talatalanoaga fa'alapotopotoga	NIP-44 v2: ECDH i le secp256k1, HKDF-SHA256, ChaCha20 ma le HMAC-SHA256, ma le faʻapipiʻiina ina ia le maua ai le umi o le siphertext le umi o le savali.
Bluetooth mesh sauniga	Pisa XX - X25519, ChaCha20-Poly1305 (IETF), Ed25519 mo saini faʻasalalau, SHA-256 ma le HMAC i lalo.
Fa'asinomaga i le malologa	AES-GCM-256. O le ki e sau mai le PBKDF2-SHA256 i le 310,000 iterations mo se faʻaupuga poʻo se PIN, poʻo mai se WebAuthn PRF gaioiga e ala i le HKDF-SHA256 mo se passkey poʻo biometric.
Valaau ma faila faila	WebRTC lava DTLS-SRTP, feutagai i luga ole NIP-17-afifi faailoilo.
Fa'alanonoa	Le tulaga CSPRNG i le taimi atoa - ki, nonces, ma le meaalofa-afifi timestamp jitter.

Puipuiga metadata

E lua faʻamatalaga i le ala afifi-meaalofa e aoga le valaʻau, aua o mea ia e ese ai le NIP-59 mai le "encrypted, ae manino mai ia te oe ia i latou":

O afifi uma e saini a tasi taimi ki faia mo na o lena savali, o lea e leai ni afifi se lua e faʻasoa se tagata e auina atu.
O afifi uma created_at o fa'afuase'i tua i tua e o'o atu i le lua itula fa'aaoga le CSPRNG, o lea e le mafai ona fa'atulaga taimi e lafo ma maua mai.

O talatalanoaga fa'atasi e fa'aopoopo i ai le fe'avea'i ephemeral e mauaina ki i luga o lena - vaai Fa'afefea ona galue fa'ailoga vaega.

Faitauina le puna

O le crypto primitives o loʻo i totonu js/nym-crypto.js ma js/modules/key-vault.js i le upega tafailagi, ma lalo ifo android-ios-app/lib/core/crypto/ ma lib/services/mesh/noise/ i le Flutter app. O le faleteuoloa o le AGPL-3.0 ma atoatoa - e leai se vaega tapuni e ave i luga o le faʻalagolago.
