Maziko a chidziwitso / Chidziwitso

Chitetezo pazida

Kubisa kumapeto mpaka kumapeto kumateteza uthenga podutsa. Tsambali ndi la theka lina: kiyi atakhala pa chipangizo chanu, ndi kuchotsa izo mofulumira.

Kwa theka laulendo - kuphatikiza kusankha quantum-resistant encryption kwa mauthenga achinsinsi ndi gulu macheza - onani masamba amenewo m'malo mwake.

Tsambali lamasuliridwa pamakina kuti zikhale zosavuta. Chingelezi choyambirira ndi chomwe chimagwira ntchito.

Identity encryption

Mwachisawawa, kiyi yachinsinsi yosungidwa imakhala pamalo osungira a chipangizocho momveka bwino. Aliyense amene angathe werengani chosungiracho - chipangizo chosatsegulidwa, chida chazamalamulo, mbiri ya osatsegula yokopera a makina ogawana - amatha kuwerenga makiyi ndikukhala inu.

Identity Encryption, pa Zochunira › Zazinsinsi & Chitetezo, zimatseka bowolo. Ndi izo:

• wanu nsec ndi encrypted pa kupuma ndi AES-GCM-256;
• makiyi achinsinsi a ephemeral anu zokambirana zamagulu dalira ndi kubisidwa pansi pa kiyi yomweyi;
• fungulo lachidule silinalembedwe ku diski pomwe kubisidwa kulipo - kulipo kokha mu kukumbukira, kokha kwa gawo;
• Kutsegula kumachitika kamodzi, pulogalamu ikayamba.

Kusankha unlock factor

Mumasankha momwe chipindacho chimatsegulidwa pachipangizochi:

PIN ndi mawu achinsinsi opangidwa ndi manambala, choncho tsatirani lalifupi monga momwemo: mwachangu, komanso mofooka.

Mantha pukuta

Dinani ndikugwira gulu la "Nym Yanu" kwa masekondi awiri. Nymchat imafafaniza chilichonse cha idakali yake pa chida, chifukwa cha umboni uliwonse wosungidwa mwa iye. Palibe confirmtion dialog, mwadala — cholinga ndichoti ingathe kuyambitsidwa mwachangu, pakakumana ndi kukakamizidwa, popanda kuonetsa chithunzi china chofunika kupita.

Kusunga komweyo kumagwira ntchito pa skrini yotsegula ya chosungidwa mwachinsinsi utambulisho: dziwani chizindikiro cha Nymchat pamwamba kwa ndani zisiki ziwiri ndipo chida chidzapangidwa popanda kutsegula chilichonse koyamba.

Makanema amfupi akuwonetsa kupita patsogolo pomwe:

1. imapempha server ya Nymchat kuti chotsalira chilichonse chimene ili nacho pa chidindo chilichonse chosungidwa — zokonza zogwirizana, zolembedwa zosungidwa za mautoli a paumwana ndi mautoli a m'magulu, komanso mbiri yosungidwa — pamene pempho lililonse limasainidwa ndi kiyi yake ya chidindo umenewo. Chiteŵa ichi chimakwanitsa... ziwiri ndi chimodzi m'mauta; kufafaniza sikudikira nthawi yaitali pa network;
2. amachotsa makiyi a chinsinsi ndi key ya vault m'chikumbutso;
3. imasunga mtengo uliwonse wamba- ndi gawo-kusungira pansi pa kiyi yatsopano mwachisawawa yomwe ili nthawi yomweyo anataya, kenaka imachotsa zikhalidwezo ndi zinyalala ndikuchotsa masitolo;
4. kuimbanso komanso kufuta database il
5. imachotsa posungira ndikuchotsa wogwira ntchito;
6. imachotsa ma cookie, kenako ndikuyikanso kumalo oyambira bwino.

Gawo lachitatu ndilo lachidwi. Kufufuta chidziwitso sikutanthauza kuti chidziwitsocho chosatheka kuchipeza, chifukwa chake pulogalamu imachichititsa chosavuta kuwerenga (encrypt) kaye ndi kiyi yomwe aliyense — kuphatikizapo pulogalamuyi — sakuisunga. Chilichonse chomwe chidzafufukira chidzakhala chizindikiro cha chidziwitso chosavuta kuwerenga (ciphertext) popanda kiyi iliyonse yomwe ilipo.

Gawo loyamba limafika pakangoti m'ma identity omwe pulogalamu ikhoza kugwiritsa ntchito kiyi yake pa nthawi imeneyo: imodzi yomwe ili okonzeka, komanso zotsala za imene zasungidwa zomwe kiyi yake ili pa chida popanda kuphimba, kapena mu browser extension yomwe imayankhula m'malo mwake. Identity imene ikadali yotsekedwa ndi kuphimba (encryption), kapena imene imasayinira kudzera mu remote signer pamene si ili okonzeka, sitinghenye pemphu limelo, choncho zolembedwa pa seva zidzasungidwa. Ngati pali zina zomwe zinasiyidwa, chidindo cha ntchito chionetsa kuchuluka kwake. Kuchotsa zonse pa chida kumachitika m'njira iliyonse.

Kufufuta zida zina zanu pokhapokha

Panic wipe imafufutanso ndithu zida zanga zina, pansi pa Settings › Privacy & Security, ndi yozimika ndipo imakhazikitsidwa malinga ndi umboni (identity). Imathira ndi malingaliro a umboniwo, choncho chida chilichonse chomwe chili chidindikidwa monga umboniwo chimadziwa kuti ili yoyaka. Kuwulitsa kumakupemphani kuti mukhazikitse, ndipo imapereka mwayi wosunga makiyi anu kaye.

Tikakhala ndi izi, panic pa chida chilichonse imachita zinthu zina ziwiri zisanachotsedwe, yozindikiridwa ndi identity: imasiya chizindikiro chaching'ono pa server ya Nymchat, ndipo imatumiza chizindikiro chomwecho ku identity yomweyo monga chopakira chinthu cholemekezedwa pa ma relay. Chida chilichonse china chomwe chili chinalidwa monga identity imeneyo chimayendetsa kafukufuku wa chizindikirocho pamene chikulumikizana, pamene chibweranso m'pamwamba ndipo mphindi zonse zisanayi. Chida chomwe chikapeza chizindikiro chomwe chadalidwa bwino komanso chatsopano kuposa kulowa kwake chimafuta identity imeneyo ndipo imachotsa, popanda kufunsa. Ma identity ena osungidwa pa chida chimenecho sakhudzedwa.

• Chizindikiro chozipereka chinyengo chimanyozedwa: chiyenera kumakhala ndi chidindo cha m’modzi mwa eni ake.
• Kulowa m'kati kachiwiri pambuyo pake kumalembetsa nthawi yatsopano yolowa ndi kuchotsa chizindikiro, choncho kulowa katsopano sikumasulidwa. Chida chomwe chikhala chochita mwa kukhala chopanda intaneti mpaka pambuyo pa kulowa kachiwiri kumeneku chikhoza kulephera kulandira chizindikirocho.
• Chizindikiro chimasungidwa kwa masiku 90, ndipo chimasunga kiyi yozindikiritsa yaikulu, nthawi ndi saini — palibe chilichonse chokhudza zomwe zida zilipo.
• Sizimayenda kudzera m' Bluetooth mesh.
• Chimene chidziwitso chofipada chimakhalabe cholocked pamene mukupandukira pa skrini yotsegulira chikhala chosatha kusaina, choncho chosatha kutumiza chizindikirochi.

Kukhiya macheza, chitetezo cha skrini ndi kibodi yobisika

Zinthu zitatu za m'mbali mwa Settings › Privacy & Security kwa munthu amene angatenge foni yanu yotsegulidwa, kapena kutiyayang'anirani m'mbuyo.

Kukolola zokambirana Konzekerani macheza, m'menyu ya m'ndandanda wa zokambirana, kumachotsa m'ndandanda wamkulu ndi kuika m' Zokambirana zotsekedwa, yomwe imatsegulidwa pokhapokha mutatsatira Face ID, chala, passkey kapena kodi ya nambala. Chida chomwe chilibe chilichonsecho chimakupemphani kuti mukhazikitse kodi ya nambala, yomwe imasungidwa pa chida chatsinthidwepo; ngati encryption ya chidindo ili yoyatsidwa, password kapena PIN yake imatsegulanso. Zokambirana zokwanaapo 100 zingalockidwe, ngakhale osati #nymchat. Zidziwitso za macheza olocked zimati okha “New message”. Zokonza kutseka macheza… Zimatsimikiza kuti zalock msanga bwanji mutachoka mu app, ndipo mutha kubisa mndandanda wa ma chat okhazikika (Locked chats) konse, kuti azitseguka pokhapokha mutalembamo kodi chinsinsi pa kapepala ka kufunafuna ka mbali ya app. Ma chat omwe ali okhazikika amapita ku zida zina zomwe muli nazo; chida chilichonse chimatsegulidwa payekha.

Chitetezo cha Skrini, yemwe imakhala yozimika mwachibadwa, imachita zimene pulatifolomu ilola. Pa Android, imabisa macheza m'malo osinthira mapulogalamu ndipo imaleza kupanga zithunzi za skrini (screenshots) komanso kurekodi skrini. Pa iOS, imabisa macheza m'malo osinthira mapulogalamu ndipo amawafunika pamene skrini ikurekodwa kapena kuonetsedwa pa chida china; iOS simalaiza mapulogalamu kuleza zithunzi za skrini. M'mabrowusa, imafooketsa macheza mutasintha pulogalamu; mabrowusa simalaiza mawebusayiti kuleza zithunzi za skrini kapena kurekodi. Imakhala yoyendetsedwa nthawi zonse m'macheza okhudzedwa komanso pa zinthu zowonera kamodzi okha.

Incognito Keyboard, zimakhala zozimira mwakutero. Pa Android imapempha keyboard kuti isaphunzire zomwe mumalemba ndipo imazimitsa malingaliro a mawu (suggestions) komanso kukonza mawu okha (autocorrect) m'mabokosi a uthenga. Pa browser imazimitsa kudzitsimikiza mawu okha (autocomplete), kukonza mawu okha (autocorrect) ndi kuunika zolakwika za malemba (spell check), koma webusayiti sitingathe kupempha app yanu ya keyboard kuti imaleka kuphunzira. iOS simapatsa mapulogalamu (apps) mwayi wotero, choncho kusinthako sikatha kuchitika pamenepo.

Zomwe zasungidwa pa chipangizo chanu

Nymchat imasunga boma kwanuko kuti itsegule nthawi yomweyo ndikugwira ntchito popanda intaneti. Mwambiri:

Zochunira › Data & Zosunga zosunga zobwezeretsera zili ndi zida ziwiri zocheperako kuposa mantha pukuta: Chotsani Chosungira Chapafupi akutsikira mbiri yosungidwa, mauthenga, mbiri ndi zochita koma kusunga malowedwe anu, zoikamo, umembala wamagulu ndi kugula; Bwezeretsani Zokonda kukhala Zosasintha amachita mosiyana.

Kuthetsa akaunti yanu

Chotsani data ya akaunti ndipo chongani chida, pamapeto pa Settings › Data & Backup, mumathetsa akaunti yanu m'kati mwa app. Imafunsa kamodzi, kenako, kwa chidziwitso chilichonse chomwe chasintha pa chida chomwe iwake (key) chingagwiritidwe ntchito, imapempha server ya Nymchat kuti chotseni zonse zimene imasunga za chidziwitsocho: settings zosinidwa ndi post-quantum recovery code, profile, PM ndi group archive, zokambirana za Nymbot, memaŵtima amene anayenerekedwa, kukopera kwa server cha zolemba zanu za pambali (public posts), balance ya Nymbot credit yanu ndi ledger yake, malipiro, invoice ndi zolemba za voucher, malipoti amene munapereka, komanso zolemba za spam-filter ndi app-check za inu. Pemphero lililonse limasainidwa ndi iwake (key) ya chidziwitsocho ndipo limatumizidwa poyimira, pakati pa masekondi angapo. Kenako imachotsa zonse pa chida m'njira yomweyo monga panic wipe ndipo imasonyeza Zamakono a akaunti achotsedwa asanabwerere ku kuyambitsa koyamba.

Musanachotsedwe data ya server ya munthu aliyense, pulogalamuyi imasunga chizindikiro chochenjera chomwe chapatsidwa chizindikiro ndi munthuyo: kiyi yake yozindikirika, nthawi, id ya chochitika, ndi chizindikiro, palibe china chilichonse, chomwe chimapasidwa kwa masiku 90.
