Isisekelo solwazi Ubunikazi

Ukuphepha kwedivayisi

Ukubethela ngasemaphethelweni kuvikela umlayezo osendleleni. Leli khasi limayelana ne enye ingxenye: ukhiye ohlezi kudivayisi yakho, nokuwususa ngokushesha.

Leli khasi lihunyushwe ngomshini ukuze kube lula. IsiNgisi sangempela inguqulo esebenzayo.

Ukubethela kobunikazi

Ngokuzenzakalelayo ukhiye oyimfihlo ogciniwe uhlala endaweni yokubeka idivayisi endaweni ecacile. Noma ubani ongakwazi funda leso sitoreji — idivayisi evuliwe, ithuluzi le-forensic, iphrofayili yesiphequluli ekopishiwe a umshini okwabelwana ngawo - angafunda ukhiye futhi abe nguwe.

Ukubethelwa kobunikazi, ngaphansi Izilungiselelo › Ubumfihlo Nokuphepha, kuvala leyo mbobo. Ngayo:

lakho nsec ibethelwe ekuphumuleni nge I-AES-GCM-256;
izikhiye zemfihlo ephemeral yakho izingxoxo zeqembu thembela kukho ibethelwe ngaphansi kokhiye ofanayo we-vault;
ukhiye wombhalo ongenalutho awubhalwanga kudiski ngenkathi ukubethela kuvuliwe - kuba khona kuphela enkumbulweni, iseshini kuphela;
Ukuvula kwenzeka kanye, uma uhlelo lokusebenza luqala.

Isigaba sezilungiselelo zobumfihlo nokuvikeleka, ngokubethela kobunikazi phezulu. — I-Identity Encryption ihlezi phezulu Kobumfihlo Nokuphepha.

Lesi silungiselelo esisodwa asivumelanisi

Isici sokuvula kanye nokhiye obethelwe kungokwendawo kudivayisi, ngakho ukubethela kobunikazi bunjalo inikwe amandla ngedivayisi ngayinye. Okuncamelayo okungazwela kuphela kokuvula/ukuvala okuhambayo phakathi kwamadivayisi, ukuze idivayisi entsha inikeze ukuyisetha nayo. Ayikho iphasiwedi, usawoti noma ukuqinisekisa kuyavunyelaniswa.

Ukukhetha isici sokuvula

Uyakhetha ukuthi i-vault ivulwa kanjani kule divayisi:

Isici	Utholakala kanjani ukhiye	Itholakala ngo
Iphasiwedi	I-PBKDF2-SHA256, 310 000 iziphindaphindo	Yonke indawo
I-PIN	Okuphuma ku-PBKDF2 okufanayo, amadijithi kuphela	Yonke indawo
Ukhiye wokungena	I-WebAuthn enesandiso se-PRF, bese kuba yi-HKDF-SHA256	Uhlelo lokusebenza lwewebhu
I-Biometric — I-Face ID, i-Touch ID, i-Windows Hello, i-biometrics ye-Android, ukhiye wokuqinisekisa ubunikazi wehadiwe	I-WebAuthn PRF kuwebhu; ukwaziswa kwe-biometric yesikhulumi ku-Android ne-iOS	Yonke indawo

I-PIN yiphasiwedi eyenziwe ngamadijithi, ngakho phatha emfushane njengaleyo ncamashi: esheshayo, futhi engenamandla.

Kungani ikucela ukuthi uvule ngokushesha

Akubona bonke abafakazeli bobuqiniso abasebenzisa isandiso se-WebAuthn PRF, nesisodwa esingasebenzisi ayikwazi ukuthola ukhiye. Ngakho-ke ngenkathi uvumela ukubethela uhlelo lokusebenza lukwenza uvule kanye, there and then — kungcono ukuthola ngokushesha kunangesikhathi esizayo uma uvula uhlelo lokusebenza olungenayo indlela yokubuyela emuva.

Sula uvalo

Cindezela bese ubamba iphaneli ethi "Nym Yakho" imizuzwana emibili. I-Nymchat ibhubhisa yonke into ukuzilandelela kudivayisi. Alikho ibhokisi lokuqinisekisa, ngenhloso - iphuzu ukuthi ingaqalwa ngokushesha, ngaphansi kwengcindezi, ngaphandle kwesikrini sesibili ukuze sidlule.

Upopayi omfushane ubonisa ukuqhubeka ngenkathi:

iwisa ukhiye wangasese kanye nokhiye we-vault kusuka kumemori;
ibhala ngemfihlo lonke inani lendawo- kanye neseshini-yesitoreji ngaphansi kokhiye omusha ongahleliwe okungukuthi ngokushesha ilahlwe, bese ibhala phezu kwalawo manani ngodoti futhi isula i izitolo;
ibhala ngaphezulu futhi isuse yonke imininingwane egciniwe ye-IndexedDB;
ithulula isitoreji senqolobane futhi ikhiphe ukubhalisa isisebenzi sesevisi;
isula amakhukhi, bese ilayisheka kabusha iye esimweni sokuqala esihlanzekile.

Isinyathelo sesibili yisona esithokozisayo. Ukususa idatha akwenzi ukuthi ingabuyiseki, ngakho uhlelo lokusebenza luyibethela kuqala ngaphansi kokhiye akekho - okuhlanganisa uhlelo lokusebenza - igcina. Noma yini esindayo ekususweni iwumbhalo wemfihlo ongenawo ukhiye okhona.

Akukho ukuhlehlisa

Ubuwena obusuliwe abubuyiseki, uwena noma yimuphi omunye. Uma i-nym ingenye oyifunayo gcina, sekela yona nsec ngaphambi kokuthi udinge lokhu. Ukuthepha okukodwa okujwayelekile kuvuliwe lelo phaneli livele livule umhleli we-nym, ngakho-ke ukusula akwenzeki ngengozi.

Yini egcinwe kudivayisi yakho

I-Nymchat igcina isifunda endaweni ukuze ivuleke khona manjalo futhi isebenze ungaxhunyiwe ku-inthanethi. Ngobubanzi:

Ini	Amanothi
Ukubhanqa kwakho ukhiye	Ibethelwe ekuphumuleni lapho ukubethela kobunikazi kuvuliwe. Akugcinwanga nhlobo kumodi ngayinye noma kumodi eqinile.
Izilungiselelo nezintandokazi	Itimu, isakhiwo, abasebenzisi abavinjiwe namagama angukhiye, iziteshi eziyintandokazi, nokunye.
Umlando wesiteshi namaphrofayili	Inqolobane yalokho okulandiwe kuma-relay.
Imilayezo eyimfihlo esuswe ukubethela nezingxoxo zeqembu	Ilawulwa ngu Cache PMs & Group Izingxoxo Kudivayisi (kuvuliwe ngokuzenzakalela). Ivale futhi aphinde alandwe futhi asuswe ukubethela ukwethulwa ngakunye esikhundleni sokuhlala kudiski.
Ubulungu beqembu nokhiye beqembu le-ephemeral	Ibethelwe ngaphansi kokhiye we-vault uma ukubethela kobunikazi kuvuliwe.
Ukuthengwa kwe-flair	Iyatholakala ngekhodi yokusebenzisa — bona isitolo se-flair.

Izilungiselelo › Idatha nesipele sinamathuluzi amabili amancane kunokwethuka sula: Sula Inqolobane Yesitoreji Sendawo yehla umlando ogciniwe, imiyalezo, amaphrofayili kanye ukusabela kodwa igcina ukungena kwakho, izilungiselelo, ubulungu beqembu kanye nokuthenga; Setha kabusha Izilungiselelo zibe Okuzenzakalelayo wenza okuphambene.
