3 3 SUMMARY Many of the "editions" of "Windows 2000", "Windows XP", "Windows Vista", "Windows 7", and "Windows 8" have the "Encrypting File System" (EFS) for securing files and/or folders inside NTFS hard drive partitions.

4 4 TOPICS Basics of Encrypting File System "EFS" versus "BitLocker" "Encrypting File System" Service Using the "Certificate Manager" to Check for Existing Personal "Public Key Certificates" Encrypting A File or Folder with EFS Using the "Certificate Manager" to Export a Newly-Created Public Key and Private Key

5 5 TOPICS (continued).PFX "Personal Information Exchange" files Decrypting an EFS-encrypted file/folder Deleted Certificates Stay in RAM And Are Active Until You Reboot

6 6 BASICS OF EFS The "Encrypting File System" (EFS) is a feature of "NTFS" hard drives (and partitions) for many editions of "Windows 2000" through "Windows 8".

7 7 BASICS OF EFS (continued) When view in "Windows Explorer" ("File Explorer"), a folder that contains only "Encrypting File System"- encrypted files will have it's name in green text:

9 9 BASICS OF EFS (continued) When viewed in "Windows Explorer" ("File Explorer"), a file that is encrypted by "Encrypting File System" will have it's name in green text:

11 11 BASICS OF EFS (continued) Another user on the same computer will be unable to open/view the EFS- protected file. If someone takes your hard drive, and puts it into an external hard drive enclosure and attaches the enclosure to their own computer, they will be unable to open/view the EFS-protected file.

14 14 BASICS OF EFS (continued) "ESF" is a feature of "NTFS" hard drives (and partitions) for many editions of "Windows 2000" through "Windows 8".

15 15 BASICS OF EFS (continued) In EFS, "public key certificates", "private keys", and passwords to controll the various keys all work together to give you "two factor authentication".

16 16 BASICS OF EFS (continued) The advantages of having certificates are detailed in ` chpaper_10_Best_Practices_Securi ng_Your_Enterprise.pdf#page=6 and 980/how-is-using-client-certificates- more-secure-than-tls-plus-basic- authentication chpaper_10_Best_Practices_Securi ng_Your_Enterprise.pdf#page=6 980/how-is-using-client-certificates- more-secure-than-tls-plus-basic- authentication

17 17 BASICS OF EFS (continued) According to ypting_File_System, Ecrypting File System (EFS) is available for the following editions of "Windows..": ypting_File_System

18 18 BASICS OF EFS (continued)

19 19 BASICS OF EFS (continued) "Windows Vista Starter", "..Home Basic", and "..Home Premium" allow only decryption--so you can read encrypted files but you cannot encrypt them according to ption1/The-Simple-Way-to-Keep- Your-Pr.htm ption1/The-Simple-Way-to-Keep- Your-Pr.htm

20 20 BASICS OF EFS (continued) For "Windows Vista Starter", "..Home Basic", and "..Home Premium" you can decrypt EFS- encrypted files using the cipher command line command. See IS/windows-vista/What-is- Encrypting-File-System-EFS IS/windows-vista/What-is- Encrypting-File-System-EFS

21 21 BASICS OF EFS (continued) "Windows 7 Starter", "..Home Basic", and "..Home Premium" allow only decryption--so you can read encrypted files but you not encrypt them

22 22 BASICS OF EFS (continued) For "Windows 7 Starter", "..Home Basic", and "..Home Premium" you can decrypt EFS-encrypted files using the cipher command line command.

23 23 BASICS OF EFS (continued) See us/windows/forum/windows_7- windows_programs/cipherexe- returns-error-the-request-is- not/9d5cb3fc-d bc9f- f62dbd46f37c?msgId=5ad136ca- dedf f1c-81627b us/windows/forum/windows_7- windows_programs/cipherexe- returns-error-the-request-is- not/9d5cb3fc-d bc9f- f62dbd46f37c?msgId=5ad136ca- dedf f1c-81627b907895

24 24 BASICS OF EFS (continued)

25 25 BASICS OF EFS (continued) "Encrypting File System" is also available for NTFS drives/partitions for the "..Pro" and "..Enterprise" editions of "Windows 8". "Encrypting File System" will not be available for the "..RT" or "Windows 8" editions of "Windows 8". Reference: s#Comparison_chartReference: s#Comparison_chart

26 26 "EFS" VERSUS "BITLOCKER" "Bitlocker" is used to encrypt entire hard drives or hard drive partitions whiile "Encrypting File System" is used to encrypt individual data files and/or folders "EFS" causes less of a performance reduction on your Windows computer
