Yog li cas yog Fernet ? Fernet yog ib txoj kev encryption symmetric uas ua kom paub tseeb tias cov lus encrypted tsis tuaj yeem siv tau / nyeem yam tsis muaj tus yuam sij. Nws siv URL nyab xeeb encoding rau cov yuam sij. Fernet kuj tseem siv 128-ntsis AES hauv CBC hom thiab PKCS7 padding, nrog HMAC siv SHA256 rau authentication.
Ib yam li ntawd, Fernet encryption yog dab tsi?
Fernet (symmetrical encryption ) Fernet guarantees cov lus encrypted siv nws tsis tuaj yeem siv los yog nyeem yam tsis muaj tus yuam sij. Fernet yog ib qho kev siv ntawm symmetrical (tseem hu ua "tus yuam sij zais cia") authenticated cryptoography . Fernet kuj tseem muaj kev txhawb nqa rau kev siv qhov tseem ceeb ntawm kev sib hloov ntawm MultiFernet.
Tom qab ntawd, lo lus nug yog, Fernet muaj zog npaum li cas? Nws feem ntau muaj 45% cawv los ntawm ntim. Nws tuaj yeem muab rau hauv chav sov lossis nrog dej khov. Thaum lub Italian liqueur muaj ib tug cult raws li nyob rau hauv lub thoob ntiaj teb bartending zej zog, nws yog heev nrov nyob rau hauv Argentina.
Kuj nug, koj siv AES encryption li cas?
Yog koj xav tau encryption ib phau ntawv muab tso rau hauv cov ntaub ntawv dawb saum toj no, teeb tsa tus yuam sij ntawm encryption ces thawb lub Nkag mus khawm. Qhov tshwm sim ntawm encryption yuav tshwm sim hauv base64 encoded los tiv thaiv cov cim encoding teeb meem.
Encryption thiab decryption ua haujlwm li cas?
Encryption yog ib tug txheej txheem uas encodes ib cov lus lossis cov ntaub ntawv kom nws tsuas yog nyeem tau los ntawm qee tus neeg. Encryption siv ib qho algorithm rau scramble, los yog encryption , cov ntaub ntawv thiab tom qab ntawd siv tus yuam sij rau cov neeg tau txais kev pabcuam kom tsis txhob sib tsoo, lossis decryption , cov ntaub ntawv.

Cov ntsiab lus hauv json web token (JWT) tsis muaj kev nyab xeeb, tab sis muaj qhov ua tau zoo rau kev txheeb xyuas qhov tseeb token. JWT yog peb qhov sib cais los ntawm lub sijhawm. Qhov thib peb yog kos npe. Tus yuam sij rau pej xeem txheeb xyuas JWT tau kos npe los ntawm nws tus yuam sij ntiag tug sib xws

Dab tsi yog kev ruaj ntseg ruaj ntseg thiab muaj nyob rau hauv kev ruaj ntseg?
Kev ceev ntiag tug txhais tau hais tias cov ntaub ntawv, cov khoom thiab cov peev txheej raug tiv thaiv los ntawm kev tsis pom zoo thiab lwm yam kev nkag. Kev ncaj ncees txhais tau tias cov ntaub ntawv raug tiv thaiv los ntawm kev hloov pauv tsis tau tso cai los xyuas kom meej tias nws ntseeg tau thiab raug. Muaj txhais tau hais tias cov neeg siv tau tso cai nkag tau rau hauv cov tshuab thiab cov peev txheej uas lawv xav tau
