Menene checksum? Da Yadda Ake Kididdige Kudi
Hanyar 1: Yi lissafin Checksums ta amfani da PowerShell
1. Yi amfani da bincike akan fara menu akan Windows 10 kuma buga PowerShell sannan ka danna' Windows PowerShell ' daga lissafin.
2.Alternatively, za ka iya dama danna kan fara kuma zaɓi ' Windows PowerShell ' daga menu.
3.A cikin Windows PowerShell, gudanar da umarni mai zuwa:
|_+_|4. Da sauri zai nuna SHA-256 ƙimar hash ta tsohuwa.
5.Don sauran algorithms, zaku iya amfani da:
|_+_|Yanzu zaku iya daidaita ƙimar da aka samu tare da ƙimar da aka bayar.
Hanyar 2: Lissafin Checksum ta amfani da Kalkuleta na Checksum Kan Layi
Akwai masu ƙididdige ƙididdiga na kan layi da yawa kamar 'onlinemd5.com'. Ana iya amfani da wannan rukunin yanar gizon don ƙididdige ƙididdigar MD5, SHA1 da SHA-256 don kowane fayil har ma da kowane rubutu.
1. Danna kan ' Zaɓi fayil ' button kuma bude fayil ɗin da kake so.
2.Alternatively, ja da sauke fayil ɗin ku a cikin akwatin da aka ba.
3.Zaɓi naka Algorithm da ake so kuma sami lissafin da ake buƙata.
4. Hakanan zaka iya daidaita wannan cak ɗin da aka samu tare da kuɗin da aka bayar ta hanyar kwafi sum ɗin da aka ba a cikin akwatin rubutu 'Compare with:'.
5.Za ku ga kaska ko giciye kusa da akwatin rubutu daidai.
Don lissafta zanta don kirtani ko rubutu kai tsaye:
a) Gungura zuwa shafin zuwa ' MD5 & SHA1 Hash Generator Don Rubutu '
b) Kwafi kirtani a cikin akwatin rubutu da aka bayar don samun adadin abin da ake buƙata.
Don sauran algorithms, zaku iya amfani da ' https://defuse.ca/checksums.htm '. Wannan rukunin yanar gizon yana ba ku ɗimbin jeri na ƙimar algorithm daban-daban na hashing. Danna 'Zaɓi fayil' don zaɓar fayil ɗin ku kuma danna ' Kididdigar Checksums… ' don samun sakamako.
Hanyar 3: Yi amfani da MD5 & SHA Checksum Utility
Na farko, zazzage MD5 & SHA Checksum Utility sannan kaddamar da shi ta danna sau biyu akan fayil ɗin exe. Kawai bincika fayil ɗin ku kuma zaku iya samun MD5, SHA1, SHA-256, ko SHA-512 hash.
