I-APOP (igama elithi "I-Post Office Protocol") isandiso se-Post Office Protocol (POP) esichazwe ku-RFC 1939 lapho iphasiwedi ithunyelwa ngefomu elibethelwe khona.
Futhi eyaziwa njenge: I- Post Office ye-Post Office eqinisekisiwe
I-APOP ifanelana kanjani ne-POP?
Nge- POP ejwayelekile, amagama abasebenzisi namaphasiwedi athunyelwa ematheksthini alula phezu kwenethiwekhi futhi angathathwa yiqembu lesithathu elinonya. I-APOP isebenzisa imfihlo eyabelwe-iphasiwedi-engazange ishintshwe ngokuqondile kodwa kuphela kwifomu eyibhaliwe etholakala kucingo oluyingqayizivele kuyo yonke inqubo yokungena ngemvume.
I-APOP isebenza kanjani?
Leyo chungechunge eyingqayizivele ngokuvamile isitembu esithunyelwe yiseva lapho uhlelo lwe-imeyili lomsebenzisi luxhuma. Kokubili isiphakeli kanye nehlelo le-imeyili lizohlanganisa i-hashed version yesitembu sesikhathi kanye nephasiwedi, uhlelo lwe-imeyili luthumela umphumela kwisiphakeli, okuqinisekisa ukuthi ukungena ngemvume kwe-hash kufana nomphumela wayo.
Kuphephile kanjani i-APOP?
Ngenkathi i-APOP ivikelekile kakhulu kunokuqinisekiswa okucacile kwe-POP, ithola ubunzima obuningi obunikeza ukusetshenziswa kwayo inkinga:
- Kokubili i-imeyli ye-imeyli kanye nenhlelo ye-imeyili okudingeka ukuyisebenzise (futhi, mhlawumbe, igcine) iphasiwedi ye-akhawunti ye-imeyli ematheksthi alula; lokhu kunikeza umzila oqondile ongayithola ukuze uthole iphasiwedi.
- I-algorithm yokubala ifomu elibhalwe ngephasiwedi, i- MD5 , libalwe futhi alisacatshangwa livikelekile. Ku-APOP, lokho akusho ukuthi njengamanje kungenzeka kalula ukuphazamisa amaphasiwedi nje kwifomu yabo ebhaliwe, kodwa kusadingeka uqaphele.
- kuyinkinga ukuthi iphasiwedi ithunyelwe ngokuphindaphindiwe, noma ngabe ifomu lekhodi; okuyinto evumela indawo engaphezulu ukuhlasela.
Kufanele ngisebenzise i-APOP?
Cha, gwema APOP ubuqiniso uma kungenzeka.
Izindlela eziphephile zokungena ngemvume kwi-akhawunti ye-imeyili ye-POP zikhona. Sebenzisa lokhu kunalokho:
- I-TLS / SSL: yonke ithrafikhi phakathi kohlelo lwe-imeyili futhi iseva ibhalwe ngekhodi; okufaka noma yiliphi igama lomsebenzisi nephasiwedi kanye nama-imeyili ngokwawo.
- I-AUTH CRAM-MD5: efana ne-APOP, i-POP AUTH evamile esebenzisa ukuqinisekiswa kwe-CRAM-MD5 ingavikeleka kakhulu njengoba iphasiwedi ingagcinwa enkambisweni; I-TLS / SSL iphakeme.
Uma unenketho kuphela phakathi kokuqinisekiswa kwe-POP ngokucacile ne-APOP, sebenzisa i-APOP ngenqubo yokungena ngemvume ephephile.
