Qhov dav tshaj plaws siv symmetrical algorithm AES-128, AES-192, AES-256. Lub ntsiab tsis zoo ntawm lub symmetric key encryption yog tias txhua tog koom nrog yuav tsum tau pauv tus siv key rau encryption cov ntaub ntawv ua ntej lawv tuaj yeem decrypt nws.
Tom qab ntawd, lub algorithm twg yog siv hauv asymmetric key cryptography?
Diffie-Hellman
Ib yam li ntawd, qhov twg symmetric encryption siv? Nyob rau hauv cov ntaub ntawv ntawm ib tug database, qhov zais cia tus yuam sij tej zaum tsuas yog muaj rau database nws tus kheej rau encryption los yog decrypt. Qee qhov piv txwv ntawm qhov twg symmetric cryptography yog siv yog: daim ntawv thov kev them nyiaj, xws li daim npav rho nyiaj uas PII xav tau kev tiv thaiv los tiv thaiv tus neeg nyiag los yog tus nqi dag.
Tsis tas li ntawd, kev sib pauv hloov pauv li cas?
Asymmetrical cryptoography feem ntau yog siv los ua pauv qhov zais cia tus yuam sij npaj rau kev siv symmetrical cryptography los encrypt cov ntaub ntawv. Hauv qhov xwm txheej ntawm a pauv qhov tseem ceeb , ib tog tsim qhov zais cia tus yuam sij thiab encrypts nws nrog pej xeem tus yuam sij ntawm tus neeg txais. Tus neeg txais yuav ces decrypt nws nrog lawv tus kheej tus yuam sij.
Vim li cas asymmetric tseem ceeb algorithms yuav ua lej ntau dua li qhov tseem ceeb symmetrical algorithms?
Asymmetric encryption : Ib public key yog siv los encrypt plaintext rau hauv ciphertext whereas tus kheej key yog siv los decrypt ib lub ciphertext. Raws li lawv koom nrog ib khub ntawm yuam sij , asymmetric algorithms nyiam ua nyuaj dua siv (thiab qeeb me ntsis kom ua tiav) tshaj symmetrical algorithms.

Vim li cas symmetric encryption sai dua asymmetric encryption?
Rau cov txheej txheem encrypt / decrypt lub luag haujlwm, symmetrical algorithms feem ntau ua tau sai dua li lawv cov asymmetrical counterparts. Qhov no yog vim lub fact tias asymmetric cryptography yog loj heev inefficient. Symmetric cryptography yog tsim los rau kev ua haujlwm zoo ntawm cov ntaub ntawv loj
Dab tsi yog qhov hloov pauv tsis siv neeg hloov pauv rau lub tshuab hluav taws xob?
Ib qho kev hloov pauv hloov yog ib qho hluav taws xob hloov hluav taws xob uas hloov lub nra ntawm ob qhov chaw. Ib qho Kev Hloov Hloov Tsis Siv Neeg (ATS) feem ntau tau teeb tsa qhov twg lub tshuab hluav taws xob thaub qab nyob, yog li lub tshuab hluav taws xob tuaj yeem muab hluav taws xob ib ntus yog tias qhov chaw siv hluav taws xob tsis ua haujlwm
Dab tsi yog symmetric cryptography algorithm?
Blowfish, AES, RC4, DES, RC5, thiab RC6 yog cov piv txwv ntawm symmetric encryption. Qhov feem ntau siv symmetrical algorithm yog AES-128, AES-192, thiab AES-256. Lub ntsiab tsis zoo ntawm tus yuam sij symmetric encryption yog tias txhua tus neeg koom nrog yuav tsum tau pauv tus yuam sij siv los encrypt cov ntaub ntawv ua ntej lawv tuaj yeem decrypt nws
Dab tsi yog qhov hloov pauv hloov pauv hloov pauv hauv Java?
Default access modifier txhais tau hais tias peb tsis qhia meej txog kev hloov pauv nkag rau hauv chav kawm, teb, txoj kev, thiab lwm yam. Ib qho kev hloov pauv lossis txoj kev tshaj tawm yam tsis muaj kev tswj xyuas kev hloov pauv yog muaj rau lwm chav kawm hauv tib lub pob
Vim li cas lo lus symmetric siv nyob rau hauv symmetric key encryption?
Symmetric Encryption yog ob-txoj kev algorithm, vim hais tias tus lej algorithm yog thim rov qab thaum lub sij hawm decryption ntawm cov lus los ntawm tib tus yuam sij zais cia. Symmetric encryption, tseem nrov hu ua private-key encryption & secure-key encryption
