Yintoni - HTTPS protocol?

HTTP - oko kukuthi, apho kusebenzayo oku, yaye kutheni ufuna? imiba yokhuseleko ezihambelana yonke - kuquka World Wide Web. Ngenxa yokwanda ixabiso lwedata zobuqu othe wasiwa phakathi iziza (hayi noko ngenxa kuphuhliso kothungelwano lwezentlalo), inxaxheba waqalisa ukuphakamisa imbambano zokhuseleko zabucala.

Kuthetha ukuthini HTTPS?

Yintoni HTTPS nendlela ukuwuqonda? Ukuba ngaba nisebenzise esi shunqulelo, kuyimfuneko ukuba ukubhala iProtokholi yokuGqithisela umbhalo okhawulezileyo Secure. Ukuze siqonde zonke iimpawu, cinga yonke. IProtokhol lisetyenziswa ukuchaza inxalenye yesiza, apho akuyomfuneko Izandiso ezongezelelweyo okanye zeempendulo - umbhalo, imifanekiso kunye neetafile. YokuGqithisela umbhalo okhawulezileyo - umgangatho ugqithiso lwedata phakathi koomatshini ezahlukeneyo, nto leyo ebonisa ukuba kufuneka abe isiqalo transmission uphawu njengoko owonyulwe data, njalo Secure - .. I transmission Idatha kwi khowudi usebenzisa SSL, nto leyo eyenza nje kuphela ungenelo nzima kodwa afumane ziyimfihlo ulwazi (iimbalelwano - oku kuphela isiqingatha edabini). uqhagamshelo olukhuselekileyo HTTP, nangona akukho ayinakutshintshwa, uvusa idata zombhalo nto leyo elinzima. Kutheni iza kucaciswa kamva.

History of uphuhliso

Ekuqaleni, uqhagamshelwano HTTP ekhuselekileyo mazisetyenziselwe kuphela qwaba ukhuseleko ingcaciso eluncedo (amanani ikhadi, passwords kubo). Kuye kwasasazwa protocol ekuqaleni kuphela intsebenziswano kunye sites zokubhankisha okanye kwiivenkile-intanethi. Ngoko, kwi-HTTP (ukuba imele ntoni) eyaziwa kuphela kubasebenzisi bezi nkonzo. Waza waqala ukudibanisa iinjini zokuphendla kunye nothungelwano ekuhlaleni, yaye kubo kwimali nezinye iisayithi. Okokuqala eyabekwa omsebenzisi kuphela kunye passwords, kodwa ngoku efanele ukubethela yonke idatha adluliselwe phakathi iseva kunye ne khompyutha yakho. Ngoku, ngaphambi kokuba uqale exchange data kunye umsebenzisi kufuneka kuqala ufake uqhagamshelwano HTTP, uze iyithumele iinkcukacha packet data.

wenza njani khowudi amaxwebhu ezosulela?

Indlela ikhowudi nobunzima kakhulu data othe wasiwa phakathi networks bha? Xa uchwetheza umyalezo kwi e-mail, phambi kokuba ifikelela kumamkeli, oko uyakwazi ukufunda ababoneleli intanethi ezahlukeneyo elinesibini. Ukuba ethile phakathi wobuqhophololo banxaxhayo - into. Ukuze wenze oku, vele uvule uqhagamshelwano. Oku kwenzeka into ngokuqhelekileyo.

Kodwa xa kusetyenziswa le HTTP protocol, oko ngokupheleleyo litshintsha meko. Inokubuyiselwa kuthelekiswa yesivumelwano phakathi computer yakho kunye neseva isiza, ecacisa ukuba yonke idatha guqulelwa kwi khowudi ibe cipher ethile, yaye ngaloo ndlela kuphela ukuba azi "ikhowudi elithi 'ukuba kunikwe indlela yoku fikelela kulwazi. Kulo mzekelo, naye nabani na ofumana imvume yokungena ukuhanjiswa kolwazi, asiyi kuba nako ukuyifunda, kuba akanayo isitshixo. Kuthiwa ithuba lokuba baziqhelanise umxholo apho, kodwa inkqubo decrypting ulwazi oluqokelelweyo luza kuba elide kakhulu (kuthatha iminyaka okanye amashumi eminyaka, ukuya iikhompyutha zinamandla).

Iimpawu encryption

Iimpawu yokusebenzisa le ndlela yonxibelelwano kuxhomekeke kwinto yokuba wadala isiqinisekiso eyahlukileyo ukuba unalo isitshixo kumsebenzisi ngamnye. Certificate of isayithi nganye zilayishwa ibhrawuza umsebenzisi, yaye indlela ngakumbi okanye mhlawumbi ngaphantsi kuphela ukuba ganga ngoku data kwixesha elizayo - ukuba ganga ngoku kulayishwa isiqinisekiso kutyelelo lwakhe lokuqala. ubude Key abe ukusuka amasuntswana-40 ukuya 256. Kodwa ezininzi sayithi banamhlanje basebenzisa ubude engundoqo 128 ziintanda. ebotshiwe ezisezantsi inokufumaneka kuphela eUnited States, apho izithintelo kumazwe angaphandle enza kutshanje. Njengoko ku iimpawu protocol kufuneka ibandakanye into yokuba kwidilesi enye Internet kungenziwa akhiwe site omnye kuphela, ikhuselwe lo protocol. Indawo sites ezininzi kunokwenzeka, kodwa ke ifuna ukusetyenziswa nezandiso ezongezelelweyo.

isiphelo

Nantso ekupheleni inqaku kwi-HTTP protocol. Yintoni na kwaye kusetyenziswa apho, wena uyazi. Khumbula ukuba lwakho ukhuseleko kwi-intanethi kwindawo yokuqala ezandleni zenu. Ngoko ke, ukuba kuyacaca ukuba HTTP kubalaseliswe obomvu, linda - kunokwenzeka ukuba kukho isithuba evumela ukuba ulahlekelwe data phakathi kwakho kunye neseva. Ngapha koko, kuyimfuneko ukuba ukusebenzisa HTTP ukuthintela iingxaki ubusela data, kwaye ukuba protocol ingxelo iingxaki, oko angena kubethwa ngoyaba. Nangona ayisoze ukukhangela ikhompyutha yakho ezingachanekanga ezifana ithegi ezingachanekanga.
