Why crypter its personal
files or its e-mails? To protect itself of course. Let
us imagine how you are ordered and that you store in a
Word file the passwords and other information which you
must type to consult your bank accounts, the services
paying of such or such sites etc... and which by bad luck
a pwith irate or a virus arrives and succeeds in knowing
all your small secrecies! I do not speak about the people
who on their place of work would like to keep certain
confidential information and to prevent some curious to
go to ferret on the right and on the left behind their
back. Therefore it is necessary of crypter from time to
time its documents.
will start with the encoding of the e-mails.
In Outlook you have the possibility of making safe your
e-mails: Sign numerically and/or crypter messages automatically
in menu tools then in Options. Choose the Security mitre
and activate the check boxs suitable in protected the
For crypter the mails it is necessary certificates for
you. The certificates enable you to be identified and
to provide you two keys. The private first and the other
public one. It is then enough to send the public key to
your correspond so that they can code the e-mails that
they will send to you. You, you will be able to read them
by the private key and so on. The public key only makes
it possible to code and not to decode. To obtain a certificate,
to contact one of the authorities available in the list
of the numerical Identifiers: go in menu tools then Options
and choose the Security mitre. Do not forget that on the
site the certificates are free!!
I remind to you that in France only the keys lower or
equal to 128 bits are authorized.... You can just as easily
use a software for crypter your messages. Most known are
PGP, GPG, A-Lock and FileCrypt.
To make safe your sendings,
you can also use the steganography:
The steganography, of the Greek steganos (covered) and
graphein (writing), is a method for hiding data without
the crypter. I.e. you to send a text hidden in a file
image or sound without the contents and the container
not being faded. Nobody will be able to believe that in
a photograph of lying of sun is dissimulated a text...
There is on the market a great number of software of steganography
but SecurEngine leaves the batch. It can dissimulate a
file within a file image of Bmp extension or JPEG, a Wav
file or even in another textual file. Moreover, the hidden
file can also be encrypted with a password over a length
of 128 bits. Lastly, it is of an incredible simplicity.
a file or a file.
For crypter a file or a file, you can always use the function
of encoding of your software of compression. The ideal
would be to use WinZip 9.0 which adopt encoding AES 128
bits and 256 bits. Moreover WinZip 9.0 can from now on
crypter the files appearing already in a file ZIP; preceding
grindings of WinZip could crypter the documents only at
the time of their filing in a Zip file.
But will know that there is always a against-parade: if
you forgot the password to decipher a zip, or if you want
at all costs to know what your owner put in the encrypted
file zip, it is enough to use Advanced Zip Password. It
will seek the combination of the password of the file:
it can test 15 million configurations to find the password
at the Second....
For those which have Windows
XP Pro, you can the crypter directly while clicking above:
Carry out a right click on the files which you wish crypter
and choose Propriety. Click on the Avanced button and
notch the box Crypte the contents to make safe the data,
then to click on button OK.
You can crypte the files one by one, or a whole file of
one only blow (in this case, the files which you will
put in the encrypted file will be automatically encrypted,
thus creating a maximum safety). For crypter a file, made
as for a file.
Technology EFS (Encrypting File System) of Windows XP
helps you to protect all your confidential data. If you
crypt a file using EFS, you are the only one with being
able to open it and work there. This protection system
is particularly appreciable on the portables because,
even in the event of loss or of flight, no one other which
is not able to you to reach the files of your hard disk.
If you do not have or do
not want to use this software or methods, pass by software
specialized in encoding.
The best would be PGP, still him! It makes it possible
to protect from the data, crypter a file, or part of the
hard disk or the second hard disk; to protect its works
and royalty... PGP is ideal of local use or e-mail. Your
own keys, you choose them well beyond the craquables 128
KB.... There are also PowerCrypt, Cryptozorus, Keyvelop
- envelope electronic, Akimania Crypto Polle......
Crypt and to decipher a file
by using technology EFS :
Click on Start/Execut then seize: gpedit.msc, then open
Strategie local computer/Parameters Windows/Parameters
of safety/local Strategies/Options of safety. Click on
Cryptographie system : use compatible algorithms FIPS
for encoding, chopping and signature HKEY_LOCAL_MACHINE

Crypt a file :
In the Windows explorer click with the right button of
the mouse on a file "test" then on the Properties
order. Click on Avanced button... and notch the Crypt
box the contents to make safe the data. A dialog box will
ask to you whether you also wish crypter the file relative
or only the file. If you click again on the Avanced button
you will have access to the Details button then. It will
be specified the name of the user whom can reach in a
transparent way the file and, possibly, the name of the
agent of recovery. If you click on the add button, it
is possible to define other users who will be able to
reach in a transparent way the file.
decontaminate the function of encoding :
Open: regedit and seek HKEY_LOCAL_MACHINE \ SOFTWARE \
Microsoft \ Windows NT \ CurrentVersion \ EFS. Create
(or modify) a Dword value named: EfsConfiguration. Affect
to him value 1.
To add the order "Crypter"
in the contextual menu of the Explorer :
Open regedit and seek HKEY_LOCAL_MACHINE \ SOFTWARE \
Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced.
Create (or modify) a Dword value, named EncryptionContextMenu
of value 1.
For crypter an Internet site.
it is enough to use WEB CRYPT PRO. It codes the HTML,
prohibited the right click, cuts out images etc...
