Zitsanzo za Checksum, Zigwiritsa Ntchito, ndi Ziwerengero
Checksum ndi zotsatira zogwiritsira ntchito algorithm, yotchedwa cryptographic hash ntchito , pa chidutswa cha deta, kawirikawiri fayilo imodzi. Poyerekeza ndi checksum yomwe mumapanga kuchokera pa fayilo yanu, ndiyi yomwe inaperekedwa ndi gwero la fayilo, zimathandiza kutsimikizira kuti fayilo yanuyi ndi yeniyeni komanso yopanda pake.
Checksum imatchedwanso nthawi yamtengo wapatali komanso kawirikawiri kawirikawiri, mtengo wahishi , kapena kokha.
Chitsanzo Chosavuta Kwambiri
Maganizo a checksum kapena cryptographic hash ntchito angawoneke zovuta ndipo sizingakhale zopindulitsa khama, koma ife tikufuna kukutsutsani inu mosiyana! Checksums kwenikweni sivuta kumvetsa kapena kulenga.
Tiyeni tiyambe ndi chitsanzo chophweka, mwachiyembekezo ndikuwonetsa mphamvu za ma checkcks kutsimikizira kuti chinachake chasintha. Mndandanda wa MD5 wa mawu otsatirawa ndi chingwe chalitali cha malemba omwe amaimira chiganizo chimenecho.
Ichi ndi mayesero. 120EA8A25E5D487BF68B5F7096440019Zolinga zathu pano, zimagwirizana. Komabe, pangani ngakhale kusintha kochepa, monga kuchotsa nthawi yokhayo, kudzabweretsa checksum yosiyana kwambiri:
Ichi ndi mayesero CE114E4501D2F4E2DCEA3E17B546F339Monga momwe mukuonera, ngakhale kusintha kochepa mu fayilo kudzabweretsa checksum yosiyana kwambiri, kuwonetsa momveka bwino kuti wina sali wosiyana.
Checksum Gwiritsani Mlanduwu
Tiyerekeze kuti mumatsitsa ndondomeko yaikulu, monga phukusi la ntchito , ku pulogalamu yomwe mumagwiritsa ntchito tsiku lililonse, ngati mkonzi wa zithunzi. Izi mwina ndi fayilo yaikulu, kutenga maminiti angapo kapena kuposerapo.
Kamodzi kamasulidwa, mumadziwa bwanji kuti fayilo imasulidwa bwino? Bwanji ngati zingapo zing'onozing'ono zimatayidwa panthawi yojambulidwa ndi fayilo yomwe muli nayo pa kompyuta yanu pakali pano sizinali zofunikira kwenikweni? Kugwiritsa ntchito ndondomeko ku pulogalamu yomwe si njira yomwe wogwirizira adalengera izo zikhoza kukubweretsani mavuto aakulu.
Apa ndi poyerekeza ndi ma checksums akhoza kuika maganizo anu kukhala omasuka. Poganiza kuti webusaitiyi mumatulutsira fayiloyi kuchokera ku deta ya data yomwe ili pafupi ndi fayiloyi, mukhoza kugwiritsa ntchito checksum calculator (onani Checksum Calculators pansipa) kuti mupange checksum kuchokera ku fayilo yanu.
Mwachitsanzo, nenani kuti webusaitiyi imapereka checksum MD5: 5a828ca5302b19ae8c7a66149f3e1e98 kwa fayilo yomwe mumasungira . Momwemo mumagwiritsa ntchito checksum yanu calculator yanu kuti mupange checksum pogwiritsira ntchito zofanana ndi cryptographic hash ntchito, MD5 mu chitsanzo ichi, pa fayilo pa kompyuta yanu. Kodi ma checksums amafanana? Mkulu! Mutha kukhala otsimikiza kuti maofesi awiriwa ali ofanana.
Kodi ma checksums sakugwirizana? Izi zikhoza kutanthawuza chirichonse kuchokera podziwa kuti winawake walowa m'malo pulogalamuyi ndi chinachake choipa popanda kudziwa, pa chifukwa chochepa choipa monga momwe iwe unatsegulira ndi kusinthira fayilo, kapena kugwirizanitsa kwa intaneti kunasokonezedwa ndipo fayilo silinathe kutsegula. Yesani kukopera fayilo kachiwiri ndikukonzekera checksum yatsopano pa fayilo yatsopano ndikuyerezeraninso.
Ma checksums amathandizanso poonetsetsa kuti fayilo yomwe mumasungira kuchokera kwinakwake kupatulapo gwero lapachiyambi, ndilo fayilo yoyenera ndipo siinasinthidwe, mwano kapena ayi, kuchokera pachiyambi. Ingoyerekezerani hayi yomwe mumalenga ndi yomwe imapezeka kuchokera ku fayilo.
Checksum Calculators
Checksum calculators ndizogwiritsidwa ntchito powerengera ma checkcks. Pali magulu ochuluka a checksum kunja uko, aliyense akuthandizira ntchito yosiyana ya cryptographic hash ntchito.
Choyimitsa chachikulu cha checksum choyambira ndi Microsoft File Checksum Integrity Verifier, yotchedwa fciv yaifupi. Fciv imangodalira kokha MD5 ndi SHA-1 zojambula zojambulajambula ntchito koma izi ndizo zotchuka kwambiri pakali pano.
Onani Mmene Mungatsimikizire Kukhulupirika kwa Mafayilo mu Windows ndi FCIV kuti muphunzire kwathunthu. Microsoft File Checksum Integrity Verifier ndi ndondomeko ya mndandanda wa malamulo koma ndi yosavuta kuigwiritsa ntchito.
Wina wabwino kwambiri wofufuza checksum wa Windows ndi IgorWare Hasher, ndipo ndiwotheka kwambiri kuti iwe usasinthe chirichonse. Ngati simukugwirizana ndi zipangizo zamakono, pulogalamuyi ndi yabwino kwambiri. Zimathandiza MD5 ndi SHA-1, komanso CRC32. Mungathe kugwiritsa ntchito Hasher ya Igor kuti mupeze checksum ya malemba ndi mafayilo.
JDigest ndi yotsegula source checksum calculator yomwe imagwira ntchito mu Windows komanso MacOS ndi Linux.
Zindikirani: Popeza kuti sikuti onse othayimbula amawunikira pulogalamu yamtundu uliwonse, onetsetsani kuti checksum iliyonse yomwe mumasankha kugwiritsa ntchito imathandizira ntchito ya hash yomwe imapanga checksum yomwe imayendetsa fayilo yomwe mumayikamo.
