MD4 Hash Ikhodi Calculator

I-MD4 (i-Message Digest 4) ngumsebenzi we-hash we-cryptographic owenzelwe nguRonald Rivest ngo-1990. Ikhiqiza inani le-hash elimisiwe le-128-bit (16-byte) kusuka ekufakeni ubude bokuzikhethela. I-MD4 manje ibhekwa njengephukile nge-cryptographically ngenxa yobuthakathaka obuvumela ukuhlaselwa kokushayisana (ukuthola okokufaka okubili okuhlukile okukhiqiza i-hash efanayo), ngakho-ke akufanele kusetshenziswe lapho kuklanywa izinhlelo ezintsha. Kufakwe lapha uma kwenzeka umuntu edinga ukukhiqiza ikhodi ye-hash ehambisanayo emuva.

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-MD4 Hash Algorithm

Angiyena isazi sezibalo, ngakho-ke ngizozama ukuchaza lo msebenzi we-hash ngendlela yokuthi ozakwethu abangewona isazi sezibalo bangaqonda ;-) Uma ukhetha incazelo enzima yezibalo, ungathola lokho kwamanye amawebhusayithi amaningi.

Kulungile, ngakho-ke cabanga nge-MD4 njenge-shredder ekhethekile yephepha. Kodwa esikhundleni shredding iphepha, it "shreds" yimuphi umyalezo (like incwadi, iphasiwedi, noma incwadi) ibe encane, fixed-usayizi irisidi. Kungakhathaliseki ukuthi umyalezo wakho mkhulu noma mncane kangakanani, le shredder ihlala ikunika irisidi encane eyi-16 bytes ncamashi (128 bits) ubude, noma izinhlamvu ze-32 ngesimo se-hexadecimal.

Ukuze uthole umyalezo shredded kahle, udinga ukuhamba ngezinyathelo ezine:

Isinyathelo 1: Ukulungiselela Umyalezo

• Ngaphambi kokuqothula, kufanele ulungise iphepha lakho ukuze lilingane ne-shredder ngokuphelele.
• Uma umyalezo wakho umfushane kakhulu, ungeza isikhala esengeziwe esingenalutho (njengama-doodle noma i-filler) ngakho-ke iphepha lilingana nesokudla nje.
• Uma inde kakhulu, uyihlukanisa ibe amakhasi amaningi osayizi ofanayo.

Isinyathelo 2: Ukwengeza Isitembu Esiyimfihlo

• Ngemuva kokulungisa umyalezo, ungeza isitembu esiyimfihlo ekugcineni esisho ukuthi umyalezo wokuqala wawude kangakanani.
• Lokhu kusiza i-shredder ukugcina usayizi wokuqala womyalezo, kungakhathaliseki ukuthi ungeze i-filler engakanani.

Isinyathelo 3: Inqubo ye-Shredding (3 Rounds of Magic)

• Manje umyalezo ungena ku-shredder.
• I-shredder inamagiya ama-4 (A, B, C, no-D) ajikeleza ndawonye ngephethini ekhethekile.
• Amagiya ahamba ngemijikelezo emi-3 yokuphotha, lapho:
  • Hlanganisa amagama
  • Flip ezinye izingxenye zibheke phansi
  • Zijikijele njenge-cube ye-Rubik
  • Smash izingcezu ezahlukene ndawonye
• Umjikelezo ngamunye wenza umyalezo ubukeke kakhulu njenge-jumbled mess engenakwenzeka ukuqaphela.

Isinyathelo 4: Irisidi Yokugcina

• Ngemuva kwakho konke ukuphotha, ukuphaphalaza, nokushaywa, i-shredder ikhipha amathe irisidi - umucu omfushane wezinombolo nezinhlamvu (i-hash).
• Lokhu irisidi njalo ubude efanayo, kungakhathaliseki uma shredded igama elilodwa noma incwadi yonke!

Ngeshwa, ngokuhamba kwesikhathi, abantu bathola ukuthi le shredder yemilingo ayiphelele. Abanye abantu abahlakaniphile bacabanga ukuthi bangakhohlisa kanjani i-shredder ekunikezeni irisidi efanayo lemiyalezo emibili ehlukene (lokhu kubizwa ngokuthi ukushayisana) nokubikezela ukuthi amagiya azojikeleza kanjani bese eyisebenzisa ukudala amarisidi amanga. Ngenxa yalokhu, i-MD4 ayisabhekwa njengephephile ezintweni ezibalulekile.
