ob tus yuam sij
Ua li no, muaj pes tsawg hom yuam sij muaj nyob rau hauv cryptography?
Muaj plaub qhov yooj yim hom ntawm tus yuam sij encryption : symmetrical, asymmetrical, public, thiab private. Thawj ob piav txog qhov twg yuam sij yog siv rau hauv encryption txheej txheem, thiab ob kawg piav qhia txog leej twg muaj kev nkag mus rau yuam sij.
Ib sab saum toj no, pes tsawg tus yuam sij raug siv hauv pej xeem tus yuam sij cryptography? ob tus yuam sij
Kuj Paub, yuav tsum muaj pes tsawg tus yuam sij asymmetric?
3 Teb. Yog li lawv yuav xav tau 499500 symmetric keys kom muaj kev sib txuas lus ruaj ntseg ntawm lawv txhua tus. Rau cov yuam sij asymmetric, txhua tus yuav muaj 2 tus yuam sij , yog li tag nrho ntawm 2000 tus yuam sij.
Dab tsi yog ob hom kev crypto txiaj tseem ceeb?
A crypto txiaj system feem ntau muaj cov algorithms, cov yuam sij, thiab cov chaw tswj xyuas qhov tseem ceeb. Muaj ob yam yooj yim ntawm cryptographic systems: symmetric ("private key") thiab asymmetric ("public key"). Symmetric key systems xav kom tus xa thiab tus neeg txais yuav tsum muaj tib tus yuam sij.

Muaj pes tsawg tus yuam sij zoo ib yam tuaj yeem muaj phau ntawv txhais lus muaj Python?
Tus yuam sij txheeb xyuas lub ntsiab lus ntawm phau ntawv txhais lus, tus nqi yog cov ntaub ntawv sib raug rau tus yuam sij muab. Cov txiaj ntsig tseem ceeb yog qhov tshwj xeeb, i. e. tsis tuaj yeem muaj ob tus yuam sij zoo ib yam hauv phau ntawv txhais lus
Ib tus yuam sij tseem ceeb puas tuaj yeem muaj ob tus yuam sij txawv teb chaws?
Nws yog qhov zoo kawg nkaus kom muaj ob kab ntawv tseem ceeb txawv teb chaws xa mus rau tib lub ntsiab lus tseem ceeb hauv ib lub rooj sib txawv vim tias txhua tus nqi tseem ceeb txawv teb chaws yuav siv cov ntaub ntawv sib txawv hauv cov lus hais
Dab tsi yog tus yuam sij ntiag tug thiab pej xeem tus yuam sij hauv Blockchain?
Thaum ib tug neeg xa koj cryptocoins hla Blockchain, lawv tau xa lawv mus rau qhov hashed version ntawm qhov hu ua "Public Key". Muaj lwm tus yuam sij uas zais ntawm lawv, uas yog hu ua "Private Key." Qhov Private Key no yog siv los muab Public Key
Koj txhais li cas los ntawm tus yuam sij ntiag tug thiab pej xeem tus yuam sij cryptography?
Nyob rau hauv pej xeem tus yuam sij cryptography, ob tus yuam sij yog siv, ib tug yuam sij yog siv rau encryption thiab thaum lwm yam yog siv rau decryption. 3. Nyob rau hauv private keycryptography, tus yuam sij yog khaws cia tsis pub leejtwg paub. Nyob rau hauv pej xeem tus yuam sij cryptography, ib qho ntawm ob tus yuam sij yog khaws cia tsis pub leejtwg paub
Ib tus yuam sij txawv teb chaws puas tuaj yeem siv lwm tus yuam sij txawv teb chaws?
1 Teb. Tus yuam sij txawv teb chaws tuaj yeem siv txhua qhov chaw uas txhais tau tias nws txawv. Yog hais tias qhov tshwj xeeb teb yog nws tus kheej txhais tau tias yog tus yuam sij txawv teb chaws, nws tsis txawv. Yog tias nws yog thaj chaw tshwj xeeb, nws kuj tuaj yeem yog lub hom phiaj ntawm lwm FK
