APOP: Okufuneka Ukwazi Ngexesha le-imeyile

I-APOP (igama elithi "I-Post Office Protocol Authenticated") isandiso sePost Office Protocol (POP) echazwe kwi-RFC 1939 apho iphasiwedi ithunyelwa kwifom efihliweyo.

Eyaziwayo njenge: I- Post Office ye-Post Office

I-APOP ifana njani nePOP?

Ngama- POP aqhelekileyo, amagama abasebenzisi kunye namaphasiwedi athunyelwa kwitekisi ecacileyo phezu kwenethiwekhi kwaye inokufunyanwa yinkampani yesithathu enobungozi. I-APOP isebenzisa imfihlo eyabelwe-iphasiwedi-engazange ichithwe ngokuthe ngqo kodwa kuphela kwifomu ebhaliweyo evela kwintambo eyingqayizivele kuyo yonke inkqubo yokungena ngemvume.

I-APOP yomsebenzi njani?

Umtya oyingqayizivele udlalwa i-timestamp ethunyelwe ngumncedisi xa inkqubo ye-imeyili yomsebenzisi idibanisa. Bobabini umncedisi kunye neprogram ye-imeyile baqulunqa i-edited version yexesha lesitampu kunye nephasiwedi, inkqubo ye-imeyili ithumela isiphumo sayo kumncedisi, oqinisekisa ubungangena kwi-hash yemiphumo yesiphumo sayo.

Ikhuseleke kangakanani APOP?

Ngelixa i-APOP ikhuseleke ngakumbi kunegunya lokuqinisekiswa kwe-POP, lijongene nenani lezinto ezimbi ezinika ingxaki yokusetyenziswa kwayo:

• Zomibini iseva ye-imeyile kunye neprogram ye-imeyli kufuneka isebenzise (kwaye, mhlawumbi, gcina) iphasiwedi ye-akhawunti ye-imeyile kwisicatshulwa esicacileyo; oku kunika indlela eya ngqo yokufumana iphasiwedi.
• I-algorithm yokuqulunqa ifom yefayile efihliweyo, i- MD5 , idethi kwaye ayisayiqwalaselwa njengekhuselekile. Ku-APOP, oko akuthethi ukuba okwamanje kulula ukunqumla iiphasiwedi nje kwifomu yabo ebhaliweyo, kodwa kusalindelekile ukuba uqaphele.
• kunzima ukuba iphasiwedi ithunyelwe ngokuphindaphindiweyo, nangona ifom efihliweyo; evumela ukuba elinye igumbi lihlaselwe.

Ngaba kufuneka ndisebenzise i-APOP?

Hayi, gweba APOP ukuqinisekiswa xa kunokwenzeka.

Izindlela ezikhuselekileyo zokungena ngemvume kwi-akhawunti ye-imeyile ye-POP zikhoyo. Sebenzisa oku endaweni:

• I-TLS / SSL: zonke izithuthi phakathi kwenkqubo ye-imeyile kwaye iseva ibhaliwe; oluquka nayiphi na igama lomsebenzisi kunye nephasiwedi kunye ne-imeyile ngokwabo.
• I-AUTH CRAM-MD5: efanayo ne-APOP, i-POP AUTH eqhelekileyo isebenzisa ukuqinisekiswa kwe-CRAM-MD5 inokukhuseleka ngakumbi njengoko iphasiwedi ingagcinwa kwinkqubo; I-TLS / SSL iphezulu.

Ukuba unokhetho kuphela phakathi kwe-POP yokuqinisekiswa kwe-POP kunye ne-APOP, sebenzisa i-APOP kwinkqubo yokungena ngemvume ekhuselekileyo.
