Ithimba leProtonMail limemezele kokuthunyelwe kwebhulogi ukuthi insizakalo yakho ye-imeyili ephephile manje isekela i-elliptic curve cryptography (ECC) ukukhulisa ukuphepha nejubane.
Ngokusho kweposi le-blog, inkampani isisebenze izinyanga ezimbalwa ukusetha ukwesekwa yezindlela ezintsha ze-cryptographic ezinikezela ngomuzwa osheshayo ngokuphepha okulinganayo noma okukhulu.
I-ECC iza kuProtonMail
I-Elliptic curve cryptography uhlelo olusezingeni eliphakeme kakhulu lwe-cryptographic olutholakalayo futhi iqembu leProtonMail manje lenza lobu buchwepheshe butholakale kubo bonke abasebenzisi kuzo zonke izinhlelo zokusebenza zewebhu, ezeselula nezedeskithophu zesevisi ye-imeyili.
I-ProtonMail izakhele igama ngokuphepha kwe-imeyili, ubumfihlo nokusebenziseka kalula.
Le nkampani yenza isinqumo sokufaka i-elliptic curve crypto ngaphezu kokubethela kweRSA. Kodwa-ke, manje I-ECC izoba yindinganiso ezenzakalelayo yawo wonke amakheli amasha ku-ProtonMail futhi iqembu leProtonMail linikeza abasebenzisi abakhona, ngokuthumela okuthunyelwe kwabo kwebhulogi, ithuba lokuvuselela amakheli abo e-RSA.
I-ECC ingenye yezinhlobo ezinamandla kakhulu ze-crypto.
Kuyisizukulwane esilandelayo se-cryptography yokhiye womphakathi, futhi kusekelwe kwizibalo. Inikeza isisekelo esiphephe kakhulu kunezinhlelo zokuqala zokubhala ngokubhala komphakathi njengeRSA.
I-ECC ingaba yindinganiso yesikhathi esizayo
Amawebhusayithi amaningi asebenzisa i-ECC ukuvikela yonke into kusuka ekuxhumaneni kwamakhasimende kwe-HTTPS ngendlela idatha edluliswa ngayo phakathi kwezikhungo zedatha.
Ngokusho kwethimba leProtonMail, uma umsebenzisi ekhathazekile ngokuqinisekisa ukuphepha okuphezulu ngenkathi egcina ukusebenza, i-ECC iyisinqumo esihle.
Ngokusho kweposi le-blog, abasebenzisi kungenzeka ukuthi sebesebenzisa le-crypto kwezinye izinsizakalo, njenge-WhatsApp, i-Chrome, i-Firefox, i-Opera ne-Tor.
Uhlelo lwe-RSA olususelwa ku-RSA olususelwa ku-RSA, nalo olusekelwe ezibalweni, luye lwaba yinsimu emkhakheni amashumi eminyaka.
I-Elliptic Curve Cryptography (ECC) iphephe kakhulu
Ngokusho kwethimba le-PrtonMail, ama-cryptosystems okhiye womphakathi, noma ngabe angama-high-bit RSA curve noma ama-curve ama-elliptical, aphephe kakhulu.
Kodwa-ke, okuwukuphela kwendlela esebenzayo yabahlaseli yokugenca noma yiluphi uhlelo lokubethela ukuxhaphaza ubuthakathaka bokusetshenziswa kwayo, kubhala iqembu.
“Nge-ECC, kunokuhlaselwa okubili kuphela okwaziwayo, okunye okusizakala ngama-generator ezinombolo ezingahleliwe kanti okunye okuxhaphaza izinto njengokusebenzisa amandla wedivayisi ukuqoqa izinkomba okhiye. Lezi zinto ezimbili ziqondakala kahle futhi sezincishisiwe iminyaka, ”kubhala iqembu.
“Sikhethe uhlelo oluthile lwamajika ayindilinga olubizwa ngeX25519, olusheshayo, oluphephile nolumelana ikakhulukazi nokuhlaselwa kokuvumelanisa. "Kulula ukukusebenzisa futhi, uma kukufanele, akuyona indaba yezicelo zamalungelo obunikazi," kwengeza iqembu.
Kusalindwe ukufika kwamakhompyutha we-quantum, inkampani yamukele okhiye be-ECC okuzoba okhiye abazenzakalelayo kuwo wonke amakheli amasha ku-ProtonMail. Le nkampani imema abasebenzisi asebevele benayo i-akhawunti yeProtonMail ukuthi bavuselele okhiye babo be-RSA kukheli ngalinye le-imeyili.
Ama-akhawunti amadala azokwazi nokujabulela i-ECC
Ukuvuselela i-akhawunti yakho, sKufanele balandele kuphela le miyalo elandelayo:
- Xhuma ku-akhawunti yakho ekhona yeProtonMail
- Kufanele baye kulo Izilungiselelo
- ukufinyelela imenyu yokhiye
- chofoza inkinobho «Faka iphasiwedi entsha» bese ukhetha ikheli ofuna ukwengeza kulo okhiye ECC bese uchofoza okulandelayo
- Bese ukhetha "X25519 (Modern, Fast, Secure)" bese uchofoza ukukhiqiza okhiye . Bazocelwa ukuthi bafake iphasiwedi ye-akhawunti yabo.
- Kumugqa wokhiye we-ECC, chofoza kumenyu yokudonsela phansi bese ukhetha "Yenza Okuyinhloko".
Lokhu kuzokwenza i-ECC ibe ukhiye ozenzakalelayo waleli kheli le-imeyili.
Inkampani incoma ukuthi ungasuli okhiye bakudala be-RSA, ngoba ukwenza kanjalo kuzolahlekelwa amandla okususa ukubhala ngama-imeyili akho akhona.
