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.

Spec ntaub ntawv nyob rau hauv angular yog dab tsi?
Cov ntaub ntawv spec yog chav ntsuas rau koj cov ntaub ntawv hauv. Lub rooj sib tham rau Angular daim ntawv thov yog kom muaj ib tug. spec. Lawv khiav siv Jasmine javascript test moj khaum los ntawm Karma test runner (https://karma-runner.github.io/) thaum koj siv ng test command
Dab tsi yog qhov zoo tshaj plaws cipher siv?
AES thiab ChaCha20 yog qhov zoo tshaj plaws symmetric ciphers siv, txij li thaum pib ntawm lub xyoo pua 21st. Qhov sib txawv ntawm lawv yog, yooj yim muab, ua ib qho thaiv thiab kwj cipher, yog li nws txawv hauv kev ceev
Dab tsi yog qhov txawv ntawm cipher thiab Cypher?
Raws li lub npe qhov txawv ntawm cipher thiab cypher yog tias cipher yog tus lej cim thaum cypher yog (cipher)
Dab tsi yog niaj hnub block cipher?
Lus Txhais • Ib tug symmetric tseem ceeb niaj hnub thaiv cipher encrypts ib n-ntsis thaiv ntawm plaintext los yog decrypts ib n-ntsis thaiv ntawm ciphertext. • Lub encryption lossis decryption algorithm siv tus yuam sij k-ntsis
Dab tsi yog qhov siv cipher suite?
Lub cipher suite yog ib txheej ntawm cov ntaub ntawv uas pab txiav txim seb koj lub web server yuav sib txuas lus ruaj ntseg cov ntaub ntawv li cas ntawm HTTPS. Lub web server siv qee cov kev cai thiab cov txheej txheem los txiav txim seb nws yuav ua li cas thiaj li muaj kev nyab xeeb rau koj lub vev xaib. Cov no yog cov khoom xyaw ntawm kev sib txuas ruaj ntseg
