Checksum Mienzaniso, Kushandisa Mhosva, uye Kuverenga
Checksum ndiyo mhinduro yekushanda sargorithm, inonzi cryptographic hash basa , pachikamu che data, kazhinji faira imwe. Kuenzanisa checksum yaunobereka kubva pane yako shanduro yefaira, neyo yakapiwa nemufananidzo wefaira, inobatsira kuti uone kuti ikopi yako yefaira ichokwadi uye isina kukanganisa.
Checksum inowanzonziwo hash sum uye zvishoma nezvishoma inokosha , hash code , kana kungova hash .
A Simple Checksum Muenzaniso
Mhedziso ye checksum kana cryptographic hash basa inogona kuoneka yakaoma uye kwete kuve yakakodzera kukosha, asi tinoda kukurudzira iwe zvimwe! Checksums chaizvo haisi iyo yakaoma kunzwisisa kana kugadzira.
Ngatitange nemuenzaniso wakajeka, tarisai kuratidza simba rechecksums kuratidza kuti chimwe chinhu chachinja. Iko MD5 checksum yemutsara unotevera ndeye tsanga yakareba yevanhu vanomiririra mutongo iwoyo.
Uyu ndiwo muedzo. 120EA8A25E5D487BF68B5F7096440019Nokuda kwezvinangwa zvedu pano, ivo vanofananirana. Zvisinei, itai kunyange shanduko shomanana, sekubvisa nguva iyo chete, ichabudisa zvakasiyana zvachose checksum:
Uyu ndiwo muedzo CE114E4501D2F4E2DCEA3E17B546F339Sezvaunogona kuona, kunyange kushandiswa kuduku mufaira kuchabudisa checksum yakasiyana, zvichiita kuti zvive pachena kuti mumwe haana kufanana nezvimwe.
Checksum Shandisa Case
Ngatiti iwe unyorera hurukudzo huru, seyeseti yebasa , kune purogiramu yaunoshandisa zuva rega rega, sejena mhariri. Izvi zvichida ihuru huru faira, kutora maminetsi akawanda kana kupfuura kuti uite.
Kamwe yakadhindwa, unoziva sei kuti faira yakakodzwa zvakanaka? Zvakadini kana zvidimbu zviduku zvakadonhwa panguva yekudzivirirwa uye faira yauri pane kombiyuta yako ikozvino haisi iyo chaiyo yaida? Kushandisa kuvandudzwa kune purogiramu iyo haisi iyo iyo yakagadzirwa nemusunguri iyo inogona kukukonzera matambudziko makuru.
Apa ndiko kuenzanisa checksums kunogona kuita kuti pfungwa dzako dzive nyore. Tichifunga kuti webhusaiti iwe wakakanda iyo faira kubva pane inopa data checksum pamwe chete nefaira kuti ibudiswe, unokwanisa kushandisa checksum calculator (ona Checksum Calculators iri pasi apa) kuti ubudise checksum kubva pane yako yakadedzwa faira.
Semuenzaniso, taura kuti webhusaiti yacho inopa checksum MD5: 5a828ca5302b19ae8c7a66149f3e1e98 yefaira yawakadzingwa . Iwe zvino shandisa yako checksum calculator kuti uite checksum uchishandisa zvakafanana cryptographic hash basa, MD5 mumuenzaniso uyu, pane faira pamakombiyuta ako. Unoita checksums here? Hukuru! Iwe unogona kuva nechivimbo kwazvo kuti mafaira maviri akafanana.
Ko checksums haina kufanana here? Izvi zvinogona kureva chimwe chinhu kubva pane chokwadi chokuti mumwe munhu akatsiva kubvumira nechokuvhiringidza kunze kwekuziva iwe, kune chikonzero chakashata chakaita sekuti iwe wakazarura uye wakashandura faira, kana hutano hwekugadzirisa hukavhiringidzika uye faira haina kumbomesa kutora. Edza kutora faira zvakare uye wobva watanga checksum itsva pane faira idzva wozoenzanisazve.
Checksums inobatsirawo pakuratidza kuti faira yawakadzingwa kubva pane imwe nzvimbo kunze kweiyo yakabva pakutanga, zvechokwadi, ine faira yakakodzera uye haina kuchinjwa, zvisiri izvo kana kuti zvimwe, kubva pakutanga. Ingofananidza iah yaunofamba neyo inowanika kubva pane faira.
Checksum Calculators
Checksum calculators ndiyo midziyo inoshandiswa kuverenga checksums. Kune zvakawanda zve checksum calculators kunze uko, imwe neimwe inotsigira rimwe rakasiyana re cryptographic hash mabasa.
Imwe huru huru checksum calculator ndeyeMicrosoft File Checksum Integrity Verifier, inonzi fciv yenguva pfupi. Fciv inotsigira chete MD5 uye SHA-1 cryptographic hash mabasa asi aya ndiwo anozivikanwa zvikuru iye zvino.
Ona Nzira Yokusimbisa Sei Faira Kuvimbika muWindows ne FCIV yekudzidzisa zvakakwana. Microsoft File Checksum Integrity Verifier chirongwa -mutsara wemirairo asi chiri nyore kwazvo kushandisa.
Imwe yakaisvonaka ye checksum calculator yeWindows is IgorWare Hasher, uye inonyatsogadziriswa saka haufaniri kuisa chero chinhu. Kana iwe usingasunungurwi nemitemo-mitsara, purogiramu iyi ingangodaro isarudzo yakanaka. Inotsigira MD5 uye SHA-1, pamwe neRC32. Unogona kushandisa Hasher IgorWa kuwana checksum yemagwaro uye mafaira.
JDigest iyi yakazaruka checksum calculator inoshanda muWindows pamwe chete ne macOS uye Linux.
Cherechedza: Sezvo kwete yose checksum calculators inotsigira zvose zvinogona kuitwa cryptographic hash mabasa, iva nechokwadi chokuti chero checksum calculator yaunosarudza kushandisa inotsigira basa rine hash rakabudisa checksum inofambidzana nefaira iwe uri kuitsvaga.
