Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Passage: Encrypting File System (EFS) na-enye ike na onye ọrụ-transparent izo ya ezo nke ọ bụla faịlụ ma ọ bụ nchekwa na NTFS olu. EFS na-arụ ọrụ na EFS ọrụ, Microsoft's CryptoAPI na EFS File System Run-Time Library (FSRTL). EFS na-arụ ọrụ site na iji igodo symmetric (nke a makwaara dị ka File Encryption Key, ma ọ bụ FEK) zoo faịlụ, nke a na-eji n'ihi na ọ na-ewe obere oge iji zoo ma wepụ data buru ibu karịa ma ọ bụrụ na ejiri asymmetric key cipher. A na-eji igodo symmetric nke ejiri zoo faịlụ ahụ na igodo ọha na eze nke jikọtara ya na onye ọrụ nke zoro faịlụ ahụ, a na-echekwa data a ezoro ezo na data data ọzọ nke faịlụ ezoro ezo. Iji decrypt faịlụ ahụ, usoro faịlụ ahụ na-eji igodo nzuzo nke onye ọrụ iji decrypt igodo symmetric nke echekwara na nkụnye eji isi mee faịlụ. Ọ na-ejizi igodo symmetric decrypt faịlụ ahụ. N'ihi na a na-eme nke a na ọkwa faịlụ faịlụ, ọ bụ ihe doro anya na onye ọrụ. Ọzọkwa, ọ bụrụ na onye ọrụ enweghi ike ịnweta igodo ha, nkwado maka igodo decryption ndị ọzọ abanyela n'ime usoro EFS, nke mere na onye ọrụ mgbake ka nwere ike ịnweta faịlụ ma ọ bụrụ na ọ dị mkpa. NTFS-nyere izo ya ezo na NTFS-nyere mkpakọ bụ ndị na-ekewaghị ekewa; Otú ọ dị, NTFS nwere ike na-eji maka otu na a-atọ ndị ọzọ ngwá ọrụ maka ndị ọzọ.  Ajụjụ: Kedu mmemme Microsoft na EFS na-arụ ọrụ?
