Ib tug CipherSuite yog ib tug suite ntawm cryptographic algorithms siv los ntawm ib tug SSL los yog TLS kev sib txuas. Ib chav suite muaj peb qhov sib txawv algorithms: Qhov sib pauv tseem ceeb thiab kev lees paub qhov tseeb, siv thaum tuav tes. Lub encryption algorithm, siv los encipher cov ntaub ntawv.

Ib yam li ntawd, nws tau nug, dab tsi yog SSL cipher?

SSL /TLS Cipher suites txiav txim siab qhov tsis sib xws ntawm HTTPS kev sib txuas. Ciphers yog cov algorithms, tshwj xeeb tshaj yog lawv yog cov txheej txheem rau kev ua haujlwm cryptographic - nws tuaj yeem yog encryption, decryption, hashing lossis kos npe digital.

Tsis tas li ntawd, SSL ciphers ua haujlwm li cas? Cipher suite. A cipher suite yog txheej txheej txheej txheem uas pab kom muaj kev sib txuas hauv network uas siv Transport Layer Security (TLS) lossis nws tam sim no-deprecated predecessor Secure Socket Layer ( SSL ). Lub bulk encryption algorithm yog siv los encrypt cov ntaub ntawv xa mus.

Tsis tas li ntawd, hloov qhov cipher spec txhais li cas?

Hloov Cipher Spec raws tu qauv. Cov hloov cipher spec raws tu qauv yog siv rau hloov tus encryption siv los ntawm tus neeg siv khoom thiab server. CCS raws tu qauv yog ib lo lus uas qhia rau cov phooj ywg tias tus xa xav tau hloov mus rau ib txheej tshiab ntawm cov yuam sij, uas yog ces tsim los ntawm cov ntaub ntawv sib pauv los ntawm handshake raws tu qauv.

Dab tsi yog SSL ciphers tsis muaj zog?

Tsis muaj SSL ciphers yog tsis muaj kev ruaj ntseg encryption/decryption txoj kev rau cov ntaub ntawv xa los ntawm HTTPS kev twb kev txuas. Nws yog ib qho tseem ceeb thaum teeb tsa TLS / SSL daim ntawv pov thawj uas koj qhib lub virtual host rau ntau yam ciphers nrog rau qhov kev txiav txim ntawm kev nyiam yog qhov ruaj ntseg tshaj plaws kom ruaj ntseg tsawg.
