Az indításhoz a következő műveletek szükségesek.
A Command Promptból nyissuk meg a cipher.exe nevű file-t, ahol a /? paraméter tájékoztat a lehetséges opciókról és azok használatáról.
Displays or alters the encryption of directories [files] on NTFS partitions.
CIPHER [/E | /D] [/S:directory] [/A] [/I] [/F] [/Q] [/H] [pathname […]]
CIPHER /U [/N]
/A Operates on files as well as directories. The encrypted file
could become decrypted when it is modified if the parent
directory is not encrypted. It is recommended that you encrypt
the file and the parent directory.
/D Decrypts the specified directories. Directories will be marked
so that files added afterward will not be encrypted.
/E Encrypts the specified directories. Directories will be marked
so that files added afterward will be encrypted.
/F Forces the encryption operation on all specified objects, even
those which are already encrypted. Already-encrypted objects
are skipped by default.
/H Displays files with the hidden or system attributes. These
files are omitted by default.
/I Continues performing the specified operation even after errors
have occurred. By default, CIPHER stops when an error is
/K Creates new file encryption key for the user running CIPHER. If
this option is chosen, all the other options will be ignored.
/N This option only works with /U. This will prevent keys being
updated. This is used to find all the encrypted files on the
/Q Reports only the most essential information.
/R Generates an EFS recovery agent key and certificate, then writes
them to a .PFX file (containing certificate and private key) and
a .CER file (containing only the certificate). An administrator
may add the contents of the .CER to the EFS recovery policy to
create the recovery agent for users, and import the .PFX to
recover individual files.
/S Performs the specified operation on directories in the given
directory and all subdirectories.
/U Tries to touch all the encrypted files on local drives. This will
update user´s file encryption key or recovery agent´s key to the
current ones if they are changed. This option does not work with
other options except /N.
/W Removes data from available unused disk space on the entire
volume. If this option is chosen, all other options are ignored.
The directory specified can be anywhere in a local volume. If it
is a mount point or points to a directory in another volume, the
data on that volume will be removed.
directory A directory path.
filename A filename without extensions.
pathname Specifies a pattern, file or directory.
Used without parameters, CIPHER displays the encryption state of
the current directory and any files it contains. You may use multiple
directory names and wildcards. You must put spaces between multiple
