Asymmetric cryptography, tseem hu ua pej xeem tus yuam sij cryptography , siv pej xeem thiab ntiag tug yuam sij rau encrypt thiab decrypt cov ntaub ntawv. Cov yuam sij tsuas yog cov lej loj uas tau ua ke ua ke tab sis tsis zoo ib yam (asymmetric). Ib qho tseem ceeb hauv khub tuaj yeem sib koom nrog txhua tus; nws hu ua pej xeem key.
Xav txog qhov no, koj yuav encrypt thiab decrypt li cas?
Cov ntsiab lus
- Cryptography yog siv los tiv thaiv thiab tiv thaiv cov ntaub ntawv thaum sib txuas lus.
- Encryption yog txheej txheem uas hloov cov ntaub ntawv qub rau hauv daim ntawv tsis paub.
- Decryption yog txheej txheem ntawm kev hloov cov ntaub ntawv encoded / encrypted nyob rau hauv ib daim ntawv uas nyeem tau thiab to taub los ntawm ib tug tib neeg los yog lub computer.
Ib tug kuj yuav nug, Kuv yuav nyeem cov lus encrypted li cas? Yuav Ua Li Cas Nyeem Encrypted Text Messages Los ntawm Textpad
- Tua tawm TextPad thiab qhib cov lus encrypted hauv qhov program.
- Xaiv tag nrho cov ntawv ntawm cov lus los ntawm nias lub khawm "Ctrl-A".
- Qhib qhov tsim nyog encryption software.
- Sau tus passphrase los yog lo lus zais uas yog thawj zaug siv los encrypt cov lus.
- Nyem "Decrypt" khawm.
Xav txog qhov no, tus yuam sij twg yog siv rau encryption?
Hauv Public tus yuam sij , ob siv cov yuam sij ib tus yuam sij yog siv rau encryption thiab lwm yam key siv rau decryption. Ib tus yuam sij (public key) yog siv rau encrypt cov ntawv dawb los hloov nws mus rau hauv ntawv cipher thiab lwm yam tus yuam sij (tus kheej key) yog siv los ntawm receiver los decrypt cov ntawv cipher los nyeem cov lus.
Kuv yuav encrypt ib cov lus nrog tus yuam sij pej xeem li cas?
Yuav ua li cas siv GPG los encrypt cov khoom
- Xyuas kom txhua yam nyob hauv ib cov ntaub ntawv.
- (Yeem xaiv) Kos npe rau cov ntaub ntawv siv koj tus yuam sij ntiag tug.
- Nkag mus rau cov ntaub ntawv siv tus neeg txais kev pabcuam pej xeem tus yuam sij.
- Xa cov ntaub ntawv encrypted thiab (yeem) kos npe rau lwm tus neeg.
- Tus neeg tau txais cov lus yuav decrypt cov ntaub ntawv encrypted siv nws tus yuam sij ntiag tug.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv hloov tus yuam sij zais cia uas siv los xyuas kom meej qhov tsis pub lwm tus paub ntawm cov lus?
Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
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
Cov lus txib twg yog siv los tshem tawm qhov tas sij hawm los ntawm tus yuam sij hauv Redis?
Redis Keys Commands Sr.No Command & Description 10 PERSIST tus yuam sij Tshem tawm qhov tas sij hawm ntawm tus yuam sij. 11 PTTL yuam sij Tau txais lub sij hawm seem hauv cov yuam sij tas sij hawm hauv milliseconds. 12 TTL tus yuam sij Tau txais cov sij hawm seem hauv cov yuam sij tas sij hawm. 13 RANDOMKEY Rov qab ib qho yuam sij los ntawm Redis
Tus yuam sij tseem ceeb thib ob thiab tus yuam sij txawv teb chaws yog dab tsi?
Txawv Teb Chaws Tseem Ceeb: Yog Lub Ntsiab Tseem Ceeb ib lub rooj tshwm (hloov-hais) hauv lwm lub rooj. Secondary (los yog lwm txoj kev) Key: Puas yog ib qho chaw hauv lub rooj uas tsis raug xaiv los ua ib qho ntawm ob hom saum toj no
