SSH muaj nws tus kheej thauj raws tu qauv ywj siab los ntawm SSL , yog li ntawd txhais tau tias SSH ua TSIS siv SSL hauv qab hood. Cryptographically, Secure Plhaub thiab Securesockets Txheej yog sib npaug. SSL cia koj siv PKI (public-key infrastructure) ntawm daim ntawv pov thawj kos npe.

Yog li ntawd, qhov twg zoo dua SSH lossis SSL?

Ntau zaus tshaj tsis, SSH siv SSL nyob rau hauv lub hood, yog li ntawd lawv ob leeg muaj kev ruaj ntseg ib leeg. Ib qho txiaj ntsig ntawm SSH yog tias kev siv key-pair authentication yog qhov ua tau yooj yim ua, thiab tsim txoj cai rau hauv cov txheej txheem. SSL txhais tau tias "Secure Sockets Layer". Tsis zoo li SSH , nws tsis tas yuav muaj authentication.

Ib sab saum toj no, qhov twg muaj kev nyab xeeb dua SSH lossis Telnet? SSH yog lub network raws tu qauv siv rau remotely access thiab tswj ib tug ntaus ntawv. Qhov sib txawv tseem ceeb ntawm Telnet thiab SSH yog tias SSH siv encryption, uas txhais tau hais tias tag nrho cov ntaub ntawv kis tau los ntawm lub network yog ruaj ntseg los ntawm eavesdropping. Zoo li Telnet , tus neeg siv nkag mus rau cov chaw taws teeb tswj yuav tsum muaj SSH neeg nruab.

Tsis tas li ntawd, qhov txawv ntawm SSH thiab SSL yog dab tsi?

Ib qho ntawm qhov pom tshaj plaws qhov sib txawv ntawm SSL /TLS thiab SSH yog uas SSL ib txwm (yog, yuav muaj kev zam) ntiav X.509 daim ntawv pov thawj digital rau server thiab cov neeg siv khoom pov thawj thaum SSH tsis. Piv txwv li, ntawm nws tus kheej, SSH tuaj yeem pab cov neeg siv nkag mus rau aserver thiab ua cov lus txib nyob deb.

SSH siv rau dab tsi?

Secure Plhaub ( SSH ) yog cryptographic networkprotocol rau kev khiav hauj lwm cov kev pab cuam network ruaj ntseg nyob rau hauv ib tug unsecurednetwork. Cov ntawv thov ib txwm muaj xws li cov chaw taws teeb hais kom ua-kab, nkag mus, thiab kev ua haujlwm hauv thaj chaw deb, tab sis txhua qhov kev pabcuam hauv network tuaj yeem tiv thaiv nrog SSH.
