Yog dab tsi - HTTPS raws tu qauv?

HTTPS - uas yog, qhov uas siv tau, thiab yog vim li cas koj xav tau? kev ruaj ntseg teeb meem yog yam qhov txhia chaw - xws li lub ntiaj teb dav Web. Nrog rau cov kev ua nqi ntawm koj tus kheej cov ntaub ntawv uas yog kis ntawm qhov chaw (tsis yog tsawg kawg vim txoj kev loj hlob ntawm kev tes hauj lwm), khwb khuav pib tsa ib qhov teeb meem ntawm kev ruaj ntseg thiab kev ceev ntiag tug.

Nws txhais li cas HTTPS?

Yuav ua li cas yog HTTPS thiab yuav ua li cas rau decipher? Yog hais tias koj tsis txhob siv cov tsiaj ntawv, nws yog tsim nyog los sau HyperText Hloov raws tu qauv ruaj ntseg. Nyob rau hauv thiaj li yuav to taub tag nrho cov nta, xav txog txhua txhua lo lus. HyperText yog siv los piav cov ib feem ntawm qhov chaw, uas tsis tas yuav ntxiv extensions los yog scripts - ntawv nyeem, dluab thiab cov ntxhuav. Hloov raws tu qauv - ib tug txheej txheem cov ntaub ntawv hloov lwm lub tsev ntawm txawv cov cav tov, uas txiav txim seb yuav tsum ua raws li ib lub teeb liab kis tau tus mob pib raws li cov ntaub ntawv, thiab lwm yam ruaj ntseg - .. Cov ntaub ntawv kis tau tus mob yog encrypted siv SSL, uas ua rau nws tsis yooj yim tsis tau tsuas yog interception tab sis kuj tau pub leej twg paub ntaub ntawv (interception - qhov no yog tsuas ib nrab ntawm cov sib ntaus sib tua). Luag twb kev txuas HTTPS, txawm hais tias nws tsis yog unbreakable, hloov lub resulting encrypted ntaub ntawv nyob rau hauv ib tug yooj yim cov ntaub ntawv. Yog vim li cas yog nws yuav tsum tau piav qhia tom qab.

Keeb kwm ntawm txoj kev loj hlob

Chiv, ib tug ruaj ntseg HTTPS kev twb kev txuas siv heev dua lwm yam rau kev tiv thaiv ntawm nqi lus (card numbers, passwords rau lawv). Nws twb faib raws tu qauv chiv xwb nyob rau hauv lub sis raug zoo nrog banking chaw los yog nyob hauv internet khw muag khoom noj. Yog li ntawd, nyob rau hauv HTTPS (dab tsi nws nruab nrab yog) tsuas rau cov neeg siv cov ntawm cov kev pab no. Ces pib mus cuag cov kev tshawb fawb xyaw thiab kev tes hauj lwm, thiab rau lawv nruj thiab lwm qhov chaw. Thawj Txoj kev no tsuas usernames thiab passwords, tab sis tam sim no amenable mus encrypt tag nrho cov ntaub ntawv xa mus ntawm neeg rau zaub mov thiab koj lub computer. Tam sim no, ua ntej koj pib cov ntaub ntawv pauv nrog rau tus neeg siv yuav tsum xub nruab ib lub HTTPS kev twb kev txuas, thiab ces forwards cov ntaub ntawv tuaj rau lawv cov ntaub ntawv.

Yuav ua li cas puas encryption ntawm kis cov ntaub ntawv?

Yuav ua li cas rau encrypt ib tug lossis loj loj ntawm cov ntaub ntawv uas yog kis ntawm ncaj tes hauj lwm? Thaum koj ntaus ib cov lus nyob rau hauv lub e-mail, ua ntej nws nce mus txog tus neeg tau kev pab, nws yuav tau nyeem ib dozen internet chaw muab kev pab. Thiab yog hais tias qhov chaw nyob rau hauv nruab nrab interpose fraudster - ib yam dab tsi nws. Ua li no, tsuas qhib kev twb kev txuas. Qhov no yog dab tsi tshwm sim feem ntau.

Tab sis yog hais tias tus HTTPS raws tu qauv siv, nws radically hloov qhov teeb meem no. Nws yuav muab piv rau daim ntawv cog lus ntawm koj lub computer thiab lub chaw neeg rau zaub mov, uas qhia tias tag nrho cov ntaub ntawv yuav encrypted rau ib cipher, thiab yog li lawv paub lub "code lo lus" uas muab kev nkag tau rau cov lus qhia. Nyob rau hauv cov ntaub ntawv no, tus neeg twg uas gains nkag tau mus rau lub khiav ntawm cov ntaub ntawv, yuav tsis tau mus nyeem nws, vim hais tias nws tsis muaj tus yuam sij. Raws sij hawm los mus paub lawv tus kheej nrog cov ntsiab lus muaj, tab sis cov txheej txheem ntawm decrypting cov ntaub ntawv yuav tsum tau ntev heev (nws yuav siv sij hawm xyoo los yog txawm xyoo lawm, mus rau feem ntau haib computers).

encryption nta

Nta ntawm kev siv ntawm cov raws tu qauv lus dag nyob rau hauv lub fact tias tsim ib daim ntawv pov thawj hais tias muaj ib tug tseem ceeb rau txhua tus neeg siv. Daim ntawv pov thawj ntawm txhua qhov chaw yog loaded rau hauv tus neeg siv lub browser, thiab tsuas yog xav paub ntxiv los yog tsawg dua tej zaum txoj kev rau kev cuam tshuam cov ntaub ntawv nyob rau hauv lub neej yav tom ntej - mus cuam tshuam cov chaw thau khoom ntawm cov ntawv pov thawj nyob rau ntawm nws thawj zaug. Ntsiab ntev yuav tsum yog los ntawm 40 mus 256 khoom. Tab sis nyob rau hauv feem ntau niaj hnub qhov chaw siv ib tug tseem ceeb ntev ntawm 128 khoom. Lower bound yuav pom heev dua lwm yam nyob rau hauv lub tebchaws United States, qhov chaw uas export txwv ua ntev los no. Raws li tus yam ntxwv ntawm lub raws tu qauv yuav tsum muaj xws li cov fact tias nyob rau hauv ib tug Internet chaw nyob yuav nyob tsuas yog ib qhov chaw, kev tiv thaiv los ntawm qhov no raws tu qauv. Qhov chaw ntawm ntau qhov chaw yog ua tau, tab sis yuav tsum tau siv ntxiv extensions.

Ntawd yog qhov kawg ntawm tsab xov xwm nyob rau hauv lub HTTPS raws tu qauv. Yuav ua li cas yog nws yog thiab qhov twg nws yog siv, koj paub. Nco ntsoov hais tias koj muaj kev ruaj ntseg nyob rau hauv Internet nyob rau hauv thawj qhov chaw nyob rau hauv koj txhais tes. Yog li ntawd, yog hais tias nws yog tseeb hais tias HTTPS yog tseem ceeb nyob rau hauv liab, tos - nws yog tau hais tias muaj yog ib co chaw uas tso cai rau koj mus poob cov ntaub ntawv ntawm koj thiab koj tus neeg rau zaub mov. Tom qab tag nrho, nws yog tsim nyog los siv HTTPS los mus tiv thaiv cov teeb meem uas muaj ntaub ntawv tub sab tub nyiag, thiab yog hais tias tus raws tu qauv qhia teeb meem, nws yuav tsis tau ignored. Txawm hais tias nws yeej tsis mob mus xyuas koj lub computer rau inaccuracies xws li tsis yog tagging.
