A checksum yog ib txoj hlua ntawm cov lej thiab cov ntawv uas ua raws li tus ntiv tes rau cov ntaub ntawv tiv thaiv uas tom qab sib piv tuaj yeem ua kom pom qhov yuam kev hauv cov ntaub ntawv. Lawv tseem ceeb vim peb siv lawv los xyuas cov ntaub ntawv kom ncaj ncees.
Tsis tas li ntawd, qhov kev siv ntawm md5 checksum yog dab tsi?
A checksum yog tus lej uas ua haujlwm raws li cov lej ntawm cov lej tseeb hauv cov ntaub ntawv, uas tuaj yeem ua tau siv tom qab ntawd txhawm rau txheeb xyuas qhov yuam kev hauv cov ntaub ntawv thaum lub sijhawm khaws cia lossis xa mus. MD 5 (Xov Xwm Digest 5) tuaj yeem ua tau siv as a checksum txhawm rau txheeb xyuas cov ntaub ntawv lossis cov hlua hauv Linux cov ntaub ntawv.
Tom qab, lo lus nug yog, vim li cas md5 phem? Thaum MD 5 feem ntau yog ib qho checksum zoo, nws tsis muaj kev ruaj ntseg li lo lus zais hashing algorithm vim nws yooj yim heev. Koj yuav xav kom koj tus neeg tawm tsam qeeb. Tsim ib qho tshwj xeeb, cryptographically ruaj ntseg random nqi rau txhua tus password (kom ob tus passwords zoo ib yam, thaum hashed, yuav tsis hash rau tib tus nqi).
Hais txog qhov no, md5 checksum txhais li cas?
Lub sij hawm: MD 5 ( checksum ) Txhais : Cov MD 5 hash algorithm yog ib qho kev siv feem ntau rau kev lees paub cov ntaub ntawv kev ncaj ncees. Lub npe yog muab los ntawm Message-Digest algorithm 5. Cov txiaj ntsig hash raug muab piv thiab, yog tias lawv phim, qhov no qhia tau tias cov ntaub ntawv tsis zoo thiab tsis tau hloov pauv.
Koj khiav checksum li cas?
- Lub checksum yog ib ntus ntawm cov lej thiab cov ntawv siv los txheeb xyuas cov ntaub ntawv tsis raug.
- Thaum Checksums siv tau.
- RELATED: Dab tsi yog tawg?
- Ntawm qhov kev ceeb toom, ntaus Get-FileHash thiab tom qab ntawd nias koj qhov chaw bar.
- Nias Enter kom khiav cov lus txib, thiab koj yuav pom SHA-256 hash rau cov ntaub ntawv.
