Umphenduli Wekhodi ye-HASH MD5

I-MD5 (i-Message Digest Algorithm 5) iwumsebenzi we-cryptographic hash osetshenziswa kabanzi okhiqiza inani le-hash elingu-128-bit (16-byte), elivame ukumelwa njengenombolo ye-hexadecimal enezinhlamvu ezingu-32. Yaklanywa nguRonald Rivest ngo-1991 futhi ivame ukusetshenziswa ukuqinisekisa ubuqotho bedatha. Nakuba ngesikhathi sokubhala ibingabhekwa njengefanele izinjongo ezihlobene nokuphepha iminyaka eminingana, kubonakala sengathi isasetshenziswa kabanzi njengesihloli sobuqotho befayela. Ngingaphakamisa ukuthi kusetshenziswe enye yezindlela eziningi ezingcono lapho kuklanywa izinhlelo ezintsha, noma kunjalo.

Ukudalulwa okuphelele: Angibhalanga ukusetshenziswa okuqondile komsebenzi we-hashi osetshenziswe kuleli khasi. Kungumsebenzi ojwayelekile ofakwe nolimi lokuhlela lwe-PHP. Ngenze isixhumi esibonakalayo sewebhu kuphela ukuze ngisenze sitholakale esidlangalaleni lapha ukuze kube lula.

Mayelana ne-MD5 Hash Algorithm

Ukuze uqonde ngempela ama-internal nomsebenzi we-hash, udinga ukuba muhle kakhulu ezibalweni futhi mina angikho kuleli zinga. Ngakho-ke, ngizozama ukuchaza lo msebenzi we-hash ngendlela abanye ochwepheshe bezibalo abangayiqonda. Uma ukhetha incazelo enembile kakhulu, enzima yezibalo, ungayithola kwamanye amawebhusayithi amaningi ;-)

Nokho, ake ucabange ukuthi i-MD5 uhlobo oluthile lwe-blender ehlakaniphile kakhulu. Ufaka noma yiluphi uhlobo lokudla (idatha yakho) kuyo - njengezithelo, imifino, noma ngisho ne-pizza - futhi uma ucindezela inkinobho, ihlala ikunikeza uhlobo olufanayo lwe-smoothie: "ikhodi ye-smoothie" enezinhlamvu ezingu-32 (i-hash ye-MD5 ngesimo se-hexadecimal).

• Uma ufaka izithako ezifanayo njalo, uzothola ikhodi ye-smoothie efanayo.
• Kodwa uma ushintsha ngisho nento eyodwa encane (njengokufafaza usawoti okukodwa), ikhodi ye-smoothie izohluka ngokuphelele.

Isebenza Kanjani "i-Blender" Ngaphakathi?

Nakuba kubonakala kumangalisa, ngaphakathi kwe-blender, i-MD5 yenza okuningi kokunquma, ukuxuba, nokuphotha:

• Chop: Ihlukanisa idatha yakho ibe yizicucu ezincane (njengokunquma izithelo).
• Hlanganisa: Ixuba izingcezu isebenzisa iresiphi eyimfihlo (imithetho yezibalo) ehlanganisa yonke into nxazonke.
• Ukuxuba: Kujikeleza konke ngokushesha okukhulu, kukuhlanganisa nekhodi engavamile engafani nhlobo neyokuqala.

Kungakhathaliseki ukuthi ufake igama elilodwa noma incwadi yonke, i-MD5 ikunikeza ikhodi enezinhlamvu ezingu-32 njalo.

I-MD5 yayivame ukuvikeleka kakhulu, kodwa abantu abahlakaniphile bathola indlela yokukhohlisa i-blender. Bathole izindlela zokudala izindlela zokupheka ezimbili ezahlukene (amafayela amabili ahlukene) agcina enekhodi efanayo ye-smoothie. Lokhu kubizwa ngokuthi ukushayisana.

Cabanga ngomuntu ekunika ikhodi ye-smoothie ethi "lena i-smoothie yezithelo enempilo," kodwa uma uyiphuza, empeleni iyinto ehluke ngokuphelele. Yingakho i-MD5 ingasaphephile ezintweni ezifana namaphasiwedi noma ukuphepha.

Abanye abantu baqhubeka bethi kulungile ekuhlolweni kobuqotho bamafayela kanye nezinjongo ezifanayo, kodwa into eyodwa ongayifuni ngempela ekuhlolweni kobuqotho bamafayela ukungqubuzana, ngoba lokho kungenza i-hash ibukeke sengathi amafayela amabili afana noma engafana. Ngakho-ke ngisho nasezindabeni ezingezona ezokuphepha, ngincoma kakhulu ukusebenzisa umsebenzi we-hash ophephile kakhulu. Ngesikhathi sokubhala, umsebenzi wami ozenzakalelayo we-hash oya kuwo ngezinhloso eziningi yi-SHA-256.

Vele, nginayo ne-calculator yalokho: Isixhumanisi.
