Tese takajaira kutumira data paInternet kana mamwe manetwork emuno. Kazhinji, data rakadaro rinotamiswa pamusoro petiweki nenzira yemabhiti. Kazhinji, kana matani edata achitumirwa pamusoro petiweki, inotarirwa kurasikirwa nedata nekuda kwenyaya yetiweki kana kurwiswa kwakashata. Cheki inoshandiswa kuve nechokwadi chekuti data yakagamuchirwa haina kukuvara uye haina zvikanganiso uye kurasikirwa. Checksum inoita sechigunwe kana chiziviso chakasarudzika che data.
Kuti unzwisise izvi zvirinani, funga izvi: Ndiri kukutumira tswanda yemaapuro kuburikidza nemumwe mumiririri wekutumira. Zvino, sezvo mumiriri wekutakura ari wechitatu bato, isu hatigone kuvimba nehuchokwadi hwake zvachose. Saka kuti ndive nechokwadi chokuti haana kudya maapuro chero api zvawo munzira yake uye kuti wagamuchira maapuro ose, ndinokudana ndokukuudza kuti ndakutumira maapuro makumi maviri. Pakugamuchira dengu, unoverenga nhamba yemaapuro uye tarisa kana ari makumi maviri.
Uku kuverengwa kwemaapuro ndizvo zvinoita checksum kufaira rako. Kana iwe watumira faira rakakura kwazvo pamusoro petiweki (wechitatu bato) kana iwe wakadhawunirodha imwe kubva painternet uye iwe uchida kuve nechokwadi chekuti faira racho ratumirwa nemazvo kana kugashirwa, iwe unoisa cheki chegurigorithmu pafaira rako ririkuitwa. akatumira uye kutaurirana kukosha kune anogamuchira. Pakugamuchira faira, anogamuchira anozoshandisa iyo algorithm uye anofananidza kukosha kwakawanikwa nezvawatumira. Kana kukosha kwacho kuchienderana, faira yakatumirwa nemazvo uye hapana data rakarasika. Asi kana hunhu hwakasiyana, mugamuchiri anozoziva ipapo kuti imwe data yarasika kana kuti faira rakakanganiswa nepanetiweki. Sezvo iyo data ingave yakanyanya kujeka uye yakakosha kwatiri, zvakakosha kuti titarise chero chikanganiso chingave chakaitika panguva yekufambisa. Saka, cheki yakakosha zvikuru kuchengetedza data rechokwadi uye kuvimbika. Kunyangwe shanduko shoma mu data inokonzera shanduko huru mucheki. Protocols seTCP/IP inotonga mitemo yekutaurirana yeinternet inoshandisawo cheki kuti ive nechokwadi chekuti nguva dzose data rakarurama rinounzwa.
A checksum inongova algorithm inoshandisa cryptographic hash basa. Iyi algorithm inoshandiswa pamusoro pechidimbu che data kana faira isati yatumira uye mushure mekuigamuchira pamusoro petiweki. Iwe unogona kunge waona kuti yakapihwa padivi peiyo yekurodha link kuitira kuti paunodhawunirodha faira, unogona kuverenga cheki pakombuta yako woienzanisa nemutengo wakapihwa. Ziva kuti kureba kwecheki hakubvi pahukuru hwe data asi pane algorithm yakashandiswa. Anonyanya kuzivikanwa chekisum algorithms anoshandiswa ndeye MD5 (Message Digest algorithm 5), SHA1 (Secure Hashing Algorithm 1), SHA-256 uye SHA-512. Aya maalgorithms anoburitsa 128-bit, 160-bit, 256 -bit uye 512-bit hashi tsika dzakateerana. SHA-256 uye SHA-512 ichangoburwa uye yakasimba kupfuura SHA-1 uye MD5, iyo mune dzimwe nguva isingawanzo gadzira iyo yakafanana checksum kukosha kwemafaira maviri akasiyana. Izvi zvakakanganisa kushanda kwealgorithms iwayo. Iwo matsva matekiniki anoratidza kukanganisa uye akavimbika. Hashing algorithm inonyanya kushandura iyo data kune yayo yebhinari yakaenzana uye yobva yatakura mamwe mabasa ekutanga se AND, OR, XOR, etc. pairi uye pakupedzisira inobvisa kukosha kwehekisi kwemakomputa.

Chii chinonzi checksum? Uye Maitiro eKuverengera Checksums
Nzira 1: Verenga Checksums uchishandisa PowerShell
1.Shandisa kutsvaga pane yekutanga menyu paWindows 10 uye nyora PowerShell uye tinya pa' Windows PowerShell ' kubva pakurongwa.
2.Alternatively, unogona kudzvanya chaipo pakatangira wosarudza ‘ Windows PowerShell ' kubva pane menyu.
3.MuWindows PowerShell, shandisa murairo unotevera:
|_+_|4.Kukurumidza kucharatidza SHA-256 hashi kukosha nekukasira.
5.Kune mamwe algorithms, unogona kushandisa:
|_+_|Iwe zvino unokwanisa kufananidza kukosha kwakawanikwa nehuwandu hwakapihwa.
Nzira 2: Verenga Checksum uchishandisa Online Checksum Calculator
Kune akawanda online checksum calculator se 'onlinemd5.com'. Saiti ino inogona kushandiswa kuverenga MD5, SHA1 uye SHA-256 cheki yechero faira uye kunyangwe chero chinyorwa.
1. Tinya pane ' Sarudza faira ' bhatani uye vhura faira yako yaunoda.
2.Alternatively, dhonza uye udonhedze faira yako mubhokisi rakapiwa.
3.Sarudza yako inodiwa algorithm uye tora inodiwa cheki.
4.Unogonawo kufananidza cheki yakawanwa iyi necheki yakapihwa nekukopa cheki yakapihwa mu‘Compare with:’ textbox.
5.Iwe uchaona tiki kana muchinjikwa padivi pebhokisi remavara maererano.
Kuverenga hashi yetambo kana zvinyorwa zvakananga:
a) Bhura pasi peji kuti ' MD5 & SHA1 Hash Jenareta Yezvinyorwa '
b) Kopa tambo mubhokisi rakapihwa kuti uwane cheki inodiwa.
Kune mamwe maalgorithms, unogona kushandisa ' https://defuse.ca/checksums.htm '. Iyi saiti inokupa iwe yakakura runyorwa rweakawanda akasiyana hashing algorithm tsika. Dzvanya pa 'Sarudza faira' kusarudza faira rako uye tinya pa ' Verenga Checksums... ' kuti uwane mhinduro.
Nzira 3: Shandisa MD5 & SHA Checksum Utility
Chekutanga, dhawunirodha iyo MD5 & SHA Checksum Utility wobva waivhura nekudzvanya kaviri pane exe faira. Ingo tarisa faira rako uye unogona kuwana yayo MD5, SHA1, SHA-256, kana SHA-512 hash. Iwe unogona zvakare kukopa-namira iyo yakapihwa hashi mubhokisi rakakodzera rekunyorera kuti rienzanise zviri nyore nehukoshi hwawanikwa.
