Rau hash ib file , nyeem nws hauv ntsis-los-ntsis thiab hloov kho tam sim no hashing functions piv txwv. Thaum tag nrho cov bytes tau muab rau cov hashing ua haujlwm hauv kev txiav txim, peb tuaj yeem tau txais qhov hex digest. Cov snippet no yuav luam tawm hash tus nqi ntawm cov ntaub ntawv teev nyob rau hauv ntaub ntawv tsim siv SHA256 algorithm.
Tsis tas li ntawd, ua li cas koj hash ib yam dab tsi hauv Python?
Hauv ib txheej, Python khaws cia txhua tus hash , thiab thaum koj ntaus yog x hauv qhov tseem ceeb:, Python yuav tau hash -tus nqi rau x, saib qhov ntawd hauv cov qauv sab hauv thiab tom qab ntawd tsuas yog sib piv x nrog cov txiaj ntsig uas muaj tib yam hash as x. Tib txoj kev siv rau kev tshawb nrhiav phau ntawv txhais lus.
Ib yam li ntawd, sha256 ntawm cov ntaub ntawv suav li cas? SHA256 Checksum Utilities
- Qhib lub qhov rais hais kom ua los ntawm nias Start >> Khiav, thiab ntaus ntawv hauv CMD.exe thiab ntaus Enter.
- Nkag mus rau txoj hauv kev ntawm daim ntawv thov sha256sum.exe.
- Nkag mus rau sha256.exe thiab sau cov npe ntawm cov ntaub ntawv koj tab tom kuaj.
- Ntaus nkag, ib txoj hlua ntawm 64 cim yuav raug tso tawm.
Khaws qhov no hauv kev pom, koj sau li cas rau hauv cov ntaub ntawv hauv python?
Cov ntsiab lus
- Python tso cai rau koj nyeem, sau thiab rho tawm cov ntaub ntawv.
- Siv cov haujlwm qhib ("filename", "w+") los tsim cov ntaub ntawv.
- Txhawm rau ntxiv cov ntaub ntawv rau cov ntaub ntawv uas twb muaj lawm siv cov lus txib qhib ("Filename", "a")
- Siv cov haujlwm nyeem los nyeem tag nrho cov ntsiab lus ntawm cov ntaub ntawv.
- Siv cov readlines muaj nuj nqi los nyeem cov ntsiab lus ntawm cov ntaub ntawv ib tug los ntawm ib tug.
Koj yuav rho tawm cov ntaub ntawv hauv Python li cas?
Txhua yam koj yuav tsum tau ua tshem tawm ib cov ntaub ntawv npe os. tshem tawm () nrog rau lub npe thiab txoj kev uas tsim nyog ( Python defaults rau cov npe tam sim no, yog li koj tsis tas yuav qhia txog txoj hauv kev yog tias qhov ntaub ntawv koj xav tau tshem tawm yog nyob rau hauv default directory).
