Zonse za hashing 

M'dziko lamakono lamakono, chitetezo cha deta ndizovuta kwambiri kwa anthu ndi mabungwe. Kuyambira pachitetezo cha mawu achinsinsi kupita ku kukhulupirika kwa data, ndikofunikira kukhala ndi njira zolimba kuti zitsimikizire chinsinsi komanso kutsimikizika kwa chidziwitso chachinsinsi. Apa ndi pamene hashing imabwera.

Hashing, njira yoyambira ya cryptographic, imapereka a yankho lamphamvu kuti muteteze deta mosasinthika.

M'nkhaniyi, tilowa mwatsatanetsatane za hashing, ndikuwunika momwe imagwirira ntchito, momwe imagwirira ntchito, komanso kufunikira kwake pachitetezo cha IT.

🚀 Kodi hash ndi chiyani? 

Hashing, m'mawu osavuta, ndikusintha kwa masamu komwe kumatenga deta yamitundu yosiyanasiyana ndikuisintha kukhala chala chapadera cha digito cha kukula kokhazikika. Chizindikiro ichi, chomwe nthawi zambiri chimatchedwa "hash", ndi cryptographic digest yomwe imafotokoza mwachidule zonse zomwe sizingasinthe.

Mwanjira ina, ndizosatheka kupanganso zomwe zidachokera ku hashi, kupangitsa hashing kukhala njira yofunikira ya njira imodzi yotsimikizira chinsinsi komanso kukhulupirika kwa chidziwitso. 

Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi hashing cheke kukhulupirika kwa datas. Powerengera zala za fayilo kapena seti ya data, zimakhala zotheka kuzindikira kusintha kulikonse kapena kusinthidwa kwa deta.

Ngakhale kusintha kwakung'ono muzolemba zoyambirira kumabweretsa chala chosiyana kotheratu, kupangitsa kuti zikhale zosavuta kuzindikira zolakwika kapena kuyesa kusintha mwachangu. 

The hashi amapezanso malo ake m'munda wa cryptography, kupereka a chitetezo cholimba chachinsinsi ndi chidziwitso chodziwika bwino. M'malo mosunga mawu achinsinsi mwachindunji m'nkhokwe, makina otetezedwa amawasunga musanawasunge.

Wogwiritsa ntchito akalowetsa mawu ake achinsinsi, amathamangitsidwanso ndikufananizidwa ndi mtengo wosungidwa wotsimikizira. Chifukwa chake, ngakhale zitakhala kuti mwalowa m'malo osavomerezeka, mawu achinsinsi amakhala osamvetsetseka.

 Komabe, si ma algorithms onse a hashing omwe amapangidwa mofanana. Ena amaonedwa kuti ndi achikale kapena ali pachiwopsezo cha kuukira kwachinsinsi.

Akatswiri achitetezo amalimbikitsa kugwiritsa ntchito ma algorithms olimba komanso okhazikika, monga SHA-256 kapena SHA-512, kuonetsetsa chitetezo chokwanira.

 🚀Chifukwa chiyani?

Ndikofunikira kugwiritsa ntchito hashi kuti muteteze zomwe zachitika kale komanso zomwe zikubwera.

Zosintha zikachitika pa netiweki, muyenera kusintha midadada yonse yam'mbuyomu komanso ma hashi omwe amalumikizana nawo. Ngati tisintha pa netiweki yonse, hashi yomwe idzapangidwe idzakhala yanu.

Nkhani yoti muwerenge: Zonse za warrant

Muyenera kufananitsa hashi yanu komanso ya netiweki kuti musatsimikizire zomwe mwachita.

Zowonadi, hashi ndi chimodzi mwazinthu zofunika pakukhazikitsa mtengo wa Markel. Chifukwa chake ndizotheka kuti ma cryptocurrencies ena aphatikizire ma hashi angapo omwe ali ndi katundu wosiyana ndi ena.

🚀Malamulo ndi katundu wa hashing

Kuti ntchito ya hashi ikhale yolondola, iyenera kulemekeza malamulo ndi katundu wina:

• Kutalika kwa siginecha zomwe zimagwiritsidwa ntchito ziyenera kukhala zofanana nthawi zonse ngakhale mutalowa bwanji. Pambuyo pake, tiwona kutalika kwa zolemba zala mu ntchito za hashi.
• Kuchokera zala zala, sizingatheke kupeza deta yoyambirira: ntchito mu hashi zimangogwira ntchito kumbali imodzi.
• Sizingatheke kulosera siginecha. Ndizosatheka kuti muyese kulingalira siginecha mwa kufufuza deta.
• Ngati muli ndi data yambiri, deta iliyonse iyenera kukhala ndi ma signature osiyanasiyana.

🚀Momwe hashing imagwirira ntchito

M'malo mwake, hashing ndi njira yodzipangira yokha yomwe imatha kufananizidwa ndi ma code omwe amatumizidwa pankhondo.

Mwachidziwitso, ndikofunikira kuwonjezera, kusintha, kapena kusintha zilembo zosiyanasiyana za uthenga kuti mupeze nambala yomwe ikuyenera kukhala yosiyana ndi ena komanso yapadera mwa mtundu wake.

Nkhani yoti muwerenge: Pezani anthu ambiri pantchito yanu

Hashi imakulolani kuti mupange kuchokera pazowonjezera zowonjezera, code yokhazikika. Ngakhale utali wa chingwecho ndi woposa zilembo 5 kapena mawu 500, uyenera kubweretsanso zotsatira ndi kukula kumodzi.

Ntchito za hash zonse zili ndi zinthu zofanana. Zomwe ndi:

• Kutsimikiza : molunjika, pambuyo pa ndimeyi kudzera mu chopukusira cha ntchito yomwe ikufunsidwa, zotsatira za uthenga, muzochitika zonse, ziyenera kukhala zosasinthika: malo, mphindi, kubwerezabwereza, ...
• La kukaniza : zotsatira zomwe zapezedwa kuchokera ku ntchitoyi siziyenera kulola aliyense kubwerera ku uthenga woyamba.
• Zosiyanitsa : chotsatira chopezedwa kuchokera ku ntchito yokhudzana ndi mauthenga awiri ofanana sayenera kukhala ofanana koma kusiyana ndi kudziwika mosavuta.
• lapadera : pambuyo posanthula, mauthenga awiri osiyana sangathe kutuluka ndi zotsatira zofanana.
• Mpikisano : zotsatira siziyenera kuchedwa, ziyenera kukhala nthawi yomweyo.

Cholinga cha hashing ndicho kulinganiza zomwe zili mkati kuti zikhale ndi chiwerengero chofanana cha zilembo ndikutha kuzindikira deta m'njira yapadera ya uthenga wina.

🚀Kugwiritsa ntchito moyenera ma hashi osiyanasiyana

Mndandandawu sunathe konse, chifukwa pali ntchito zina zingapo za izi:

• Fananizani mawu achinsinsi : monga zanenedwa, posunga mawu achinsinsi, zonse zimachitika kuti chitetezo.
• Kutsimikizira zomwe mwatsitsa : Nthawi zina mwachitsanzo, mukatsitsa fayilo kuchokera pa intaneti, siginecha yoyambirira ya fayiloyo ilipo.

Imawonetsedwa mwachindunji patsambalo kapena mufayilo ina yomwe ili yosiyana. Kuti ndikutsimikizireni kuti fayiloyo idatsitsidwa molondola, muyenera kungoyang'ana kuti siginecha ya fayiloyo ndiyofanana ndi yomwe yaperekedwa.

• Siginecha ya digito kapena yamagetsi yamakalatas: apa, zolembazo zimatumizidwa mwachindunji ku ntchito ya hashi. Zolembazo zimatumizidwa nthawi yomweyo monga zala zala. Wogwiritsa ntchito amangofunikira kufotokozera zala zomwe adalandira ndikutsimikizira kuti zikugwirizana ndi kuwerengera zala zala zomwe zalumikizidwa ku data yomwe walandilidwa.
• Kugwiritsa ntchito hash table : Ngati mukufuna kutero, muyenera kuzigwiritsa ntchito popanga mapulogalamu kuti zonse ziyende bwino.
• Ponena za kusunga deta : kuti ndikutsimikizireni za kukhalapo kwa chikalatacho, muyenera kudzitsimikizira nokha kuti siginecha iliponso, kotero simuyenera kuisunganso. Izi zimayamikiridwa kwambiri, chifukwa ngati ndi fayilo yomwe ili yayikulu, zidzakutengerani nthawi yocheperako kuti muwerenge siginecha ya chala cholembetsedwa.

🚀Kugwiritsa ntchito hash coding

Chomwe chimasunga mawu anu achinsinsi kukhala otetezeka ndi chomwe chimatenga mawu achinsinsi anu ndikuwapera kukhala siginecha. Siginecha iyi imatchedwanso amaonekera ".

Kompyutayo situmiza mawu achinsinsi ku seva, imangotumiza siginecha yanu yachinsinsi. Panthawiyi, seva sichisunga mawu achinsinsi, koma siginecha yomwe yaphwanyidwa.

Nkhani kuwerenga: Kodi kubetcherana pa Live TV Games pa 1xbet 

Kompyuta ikalumikizana, seva sidzatsimikizira dzina lanu lachinsinsi, koma ngati siginecha ya mawu anu achinsinsi ndi ofanana ndi omwe adalembetsedwa.

Chifukwa chake musadandaule za aliyense amene akugwiritsa ntchito mawu achinsinsi anu, chifukwa ntchito ya hashi imachepetsa kuchuluka kwa magalimoto ndi mawu achinsinsi.

🚀Ma hashi otchuka

Tsopano tikuwonetsani zina zodziwika bwino ndi masamba ena omwe amakuthandizani.

⚡️MD5

Ndithudi anthu ena adamvapo kale. Ntchito ya hashiyi imagwiritsidwa ntchito bwino kwambiri ndipo makamaka ponena za chitetezo, ndibwino kuti musinthe ku mtundu wamphamvu kwambiri womwe ulipo, chifukwa zotsatira za kugunda zilipo.

Nkhani yoti muwerenge: Sinthani bwino maakaunti anu abizinesi 

Dziwani kuti ntchitoyi imabwezera mwachindunji hashi ya 128-bit.

⚡️SHA1

SHA1 kale anali ntchito yolowa m'malo mwa MD5, chifukwa idatumiza ma hashe 160-bit ndipo sinapatse mwayi wokumana ndi zogundana.

Izi zinasintha kuchokera ku 2004-2005, pamene kuukira kangapo kunawonetsa kuthekera kopanga kugunda.

Kuyambira tsiku limenelo, sikoyenera kugwiritsa ntchito ntchitoyi ya SHA1. Koma masiku ano, anthu ambiri amagwiritsabe ntchito ntchitoyi.

Pofika pa Disembala 31, 2016, masatifiketi a digito omwe adagwiritsa ntchito SHA1 salinso ovomerezeka.

⚡️SHA2

Muphatikizepo SHA256 et SHA512, ndiwo miyezo iwiri ikuluikulu yomwe ikugwiritsidwa ntchito pakali pano.

Tikunena izi motsimikiza, chifukwa sitinapezebe ziwopsezo zachitetezo pazinthu zosiyanasiyanazi. Iwo ali ndi kuthekera kopanga siginecha mu utali motsatana wa 256 ndi 512 bit.

Pomaliza, tikudziwitsani zamasamba omwe amakupatsani mwayi wopanga masiginecha a digito okhala ndi mafayilo kapena data, komanso kugwiritsa ntchito ma hashi osiyanasiyana.

• Ngati mukufuna kubisa mawu, muli ndi: http//www.cryptage-md5.com/
• Kubisa mu Chingerezi: http://onlinemd5.com/

Onetsetsani kuti muwagwiritse ntchito bwino kuti mupindule ndi ntchito zawo.

🚀Mapeto

Hashi si ntchito ya masamu chabe. Ndi chida champhamvu m'munda wa chitetezo kompyuta. M'nkhaniyi, tafufuza zoyambira za hashing komanso kufunikira kwake pamawonekedwe amakono a digito. 

Taphunzira kuti hashing imapereka njira yabwino yotsimikizira kukhulupirika kwa deta, kuzindikira kusokoneza kapena zolakwika. Kuphatikiza apo, imagwira ntchito yofunika kwambiri pakusunga mawu achinsinsi, kuwapangitsa kukhala osasweka ndikuteteza zidziwitso zachinsinsi. 

Nkhani yoti muwerenge: Momwe mungalipire pulojekiti yanu pa bajeti yolimba?

Kupitilira izi zomwe zimagwiritsidwa ntchito wamba, tapezanso kugwiritsa ntchito kangapo kwa hashing m'magawo osiyanasiyana apakompyuta. Kaya ndikusungirako deta, kuchotsera, matebulo a hashi kapena kubweza zambiri, hashing imakhala chida chosunthika komanso chothandiza. 

Komabe, ndikofunikira kusankha ma hashing algorithm mosamala malinga ndi zosowa zenizeni. mayendedwe apano, monga SHA-256 kapena SHA-512, perekani chitetezo chapamwamba ndipo chiyenera kukondedwa kuposa ma aligorivimu akale kapena osatetezeka. 

Mafunso Ofunsidwa Kawirikawiri

⚡️Timagwiritsa ntchito chiyani hashi?

Chochititsa chidwi mu hashi sichinthu chomwe chikufunsidwa, koma ma signature awo omwe amalola kuti pakhale chitetezo chabwino cha deta.

⚡️Kodi kugundana kwa hashi ndi chiyani?

Kugundana kumayimiridwa pamene deta zingapo zosiyana kuchokera kwa wina ndi mzake zimapereka zala zofanana. Koma musadandaule ngati izi zichitika, chifukwa ndi nkhani yongoyang'ana mophweka ngati chala chomwe tidalandira pa data ndi chofanana ndi zomwe zatumizidwa.

Tamaliza!!

 Tikukhulupirira kuti mudakhutitsidwa ndikuti ntchito za hashi zilibenso zinsinsi zanu.
