Encrypting File System

(also EFS)

Encrypting File System definition

Encrypting File System is a component of Microsoft Windows that permits users to cipher individual files or directories. It safeguards their data from prying eyes. When a document is sealed using EFS, only the individual with the appropriate decryption passphrase can unveil its contents. If an outsider without the access code attempts to view or alter the ciphered document, they'll encounter barriers. This protection technique is especially beneficial for shielding delicate data.
