Everyone has his own secretsand of course secrets can’t be told, be seen, or be read by others. It
is the same way that everyone has his own secret files which doesn’t
want other to be able to open them. These files may be diaries, stories
or even files contain passwords or credit card information. The
security software usually doesn't help us to protect these, we have to
do it by ourselves. This is a list of ways and applications which can
be used to protect our secret files.
7-Zip
Using 7-Zip or
other compressors may be the simplest way to password protect files.
Although this way is quite simple, it is pretty easy and efficient to
password protect a file or folder. Just compress what you want with a
password, then delete the source files so that when you want to open
that file, you must enter a right password in order to use. You may use
the password compressed file to send your friends without any worries
that someone can open it. Of course, the recipient must have the right
password to open it. If you are afraid that there is no compressor
already installed on the recipient’s computer, instead of compressing
to the usual format, you should use the self-extract type which can be
run on any computers.
Androsa FileProtector
Androsa FileProtector
is a free and exclusive for password protecting files. The usage is
quite easy and straightforward. You just simply add files or folder
using its file manager, then set a password and the algorithm to
protect them. The algorithm may be DES
64 bits to Rijdael
(AES) 256 bits (the longer, the better). Androsa FileProtector
will then encrypt and change the extension of selected files to .afp. Once you open
these files, you must enter a right password in order to open them.
This feature is only available on computers which have already
installed Androsa
FileProtector. So when you send the afp files to others
and are not sure whether the software has been installed on their
computers, you may use the Self-Decrypting
archive instead of the .afp.
Empathy
Empathy
is an ideal utility to password protect executable files from being run
by others. Once you set a password to protect, the executable file
would ask for a right password to be able to run. Empathy is free,
portable, simple and straightforward utility. However, there’s a weird
thing that you just can set password with a letter in unregistered
version. To remove this limitation, you must send the author a postcard
includes your email, and then he’ll send you the registration code.
My Lockbox
My
Lockbox is a free and small utility to password protect your
folders in Windows. This is handy and useful when you just want to hide
files and folders from others. The protected folder will be hidden from
any user and application of your system, including Administrator and
System itself. However, the protected folder will be easily caught by
folks who boot your computer from a Live Linux CD.
PixelCryptor
Not like others, PixelCryptor
uses an image as the key to encrypt and decrypt secret package. PixelCryptor lets
you choose a picture and use it combine your files into a package. All
we know that images are always easier to remember than a bunch of
letters of a password. The usage is quite easy although there are more
steps than others. In the main window, simply add files or folders you
want to password protect, next add an image as the key for encryption.
You do the same to decrypt the package, just enter the path of your
image instead of a password and click Next to decrypt.
