<prompt> Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu: Passage: Encrypting File System EFS inopa simba uye mushandisi-transparent encryption yechero faira kana folda pane NTFS vhoriyamu. EFS inoshanda pamwe chete neEFS service, Microsofts CryptoAPI uye EFS File System Run-Time Library FSRTL. EFS inoshanda nekunyorera faira ine bulk symmetric kiyi inozivikanwawo seFaira Encryption Key, kana FEK, iyo inoshandiswa nekuti zvinotora nguva shoma yekunyorera uye kudonhedza huwandu hwakawanda hwe data pane kana asymmetric kiyi cipher ichishandiswa. The symmetric kiyi kuti rinoshandiswa encrypt faira iri ipapo encrypted ane pachena kiyi kuti chokuita mushandisi uyo encrypted faira, uye ichi encrypted mashoko inochengetwa mune imwe date rukova encrypted faira. Kuti adzivirire faira racho, faira racho rinoshandisa kiyi yomunhu oga yomushandisi kuti adzivirire kiyi ye symmetric iyo inochengetwa mumusoro wefaira. Inobva yashandisa kiyi yokuenzanisa kududzira faira racho. Nemhaka yokuti ikoku kunoitwa pamwero wegadziriro yefaira, kunooneka kumushandisi. Uyewo, kana mushandisi akarasikirwa nekodzero yekuwana kiyi yavo, rutsigiro rwemamwe makiyi ekududzira akavakirwa muEFS system, kuitira kuti mumiririri wekudzorera agone kuwana mafaira kana zvichidikanwa. NTFS-anopa encryption uye NTFS-anopa compression vari yakawiriranwa; zvisinei, NTFS inogona kushandiswa mumwe uye wechitatu-vebato chokushandisa mumwe. Mubvunzo: Ipurogiramu ipi yeMicrosoft inoshanda neEFS pamwe chete?  <response>: CryptoAPI
