System
Requirements
At least 64 Mb RAM and
Windows 95/98/Me/NT/2000/XP
2.
How
to install EncryptIt?
Download encryptit.exe
file and run it. Follow the instructions on screen to complete the
installation.
3.
How
to start EncryptIt?
To start EncryptIt:
Start
| Programs | EncryptIt | EncryptIt 2.01
4.
What
is a key?
You use a key to lock and
unlock a file. It is like a password. When a file is encrypted, its
contents become inaccessible. To decrypt it and restore the file,
you need the key to start the process. Without the key, no one can
successfully decrypt the file and read the file.
The key has to be at least
8 characters (64 bits) in length.
5.
How
to encrypt a file?
Remember: do not try to
encrypt any files that are important to your operating system or
other application software. Do not try to encrypt system files that
are need by Windows operating system.
To encrypt a file:
-
Enter a key and
confirm the key.
-
Choose the
file you
want to encrypt from the file list box. If you want to encrypt all the files in a folder,
make sure to have
All files in folder
in the
Options checked. With
All files in folder
on, all the files will be automatically selected when you select
a folder from the folder list.
-
By default, the
original file will be overwritten by its encrypted version. If
you want to use different name for the encrypted version and
preserve the original one, uncheck Overwrite existing file.
You then enter a file name in the New File Name box.
-
Click on Encrypt
button and Yes to confirm the encryption.
Remember the key. You will
need the key to decrypt the file.

How
to decrypt a file?
Decrypting files is very
similar to encrypting them except the Decrypt button used.
-
Enter a key and
confirm the key.
-
Choose the
file you
want to decrypt from the file list box. If you want to decrypt all the files in a folder,
make sure to have All files in folder
in the Options checked. With All files in folder on, all
the files will be automatically selected when you select a
folder from the folder list.
-
By default, the
encrypted version will be overwritten by its original version.
If you want to preserve the encrypted one, uncheck Overwrite
existing file. You then enter a file name in the New File
Name box.
-
Click on Decrypt
button and Yes to confirm the decryption.
7.
How
to create a self decrypting file?
EncryptIt allows you to
create a self decrypting file that you can send or transfer to
people who do not have EncryptIt installed. The file contents can be
unlocked with your key without using any software programs.
To create a self
decrypting file:
-
Enter a key and
confirm the key.
-
Choose the file you
want to encrypt from the file list box.
-
Click on Create
Self Decrypting File button and the Self Decrypting File
Wizard will appear.
-
Make changes with the
output file name if you want and click on Creating Self
Decrypting File button. The output file will be created and
placed in the same folder as the file you choose to encrypt.
8.
How to unlock a self decrypting file? The
self decrypting file is an .exe file. Just run it. You will be
promoted to enter the key. Enter the key and click on the Decrypt. 9.
How can I email an encrypted file?
You
can send an email directly from EncryptIt. Choose Send Email from
the Tools menu. It will start your standard email program. You can
send the encrypted file as an file attachment.
10.
How
to uninstall EncryptIt?
To uninstall EncryptIt, Start
| Programs | EncryptIt | Uninstall l EncryptIt
2.01.

Algorithms
used in EncryptIt
EncryptIt uses 448 bit
Blowfish algorithm, 168 bit Triple-DES encryption algorithm, and 256
bits AES encryption algorithm to create secured files. You select
one of them to encrypt files.
Blowfish:
Blowfish is a symmetric
block cipher that can be used as a drop-in replacement for DES or
IDEA. It takes a variable-length key, from 32 bits to 448 bits,
making it ideal for both domestic and exportable use. Blowfish was
designed by Bruce Schneier in 1993 as a fast, free alternative to
existing encryption algorithms. Since then it has been analyzed
considerably, and it is slowly gaining acceptance as a strong
encryption algorithm.
Triple-DES:
Triple-DES is a secure
variation of the Data Encryption
Standard first developed by IBM,
and later in 1977 adopted by the U.S.
Government. The DES algorithm is still
widely used and is still considered reasonably secure. There is no
feasible way to break DES.
AES:
It was the winner
of the competition for the new Advanced Encryption Standard that
will replace the old US government standard. AES has a variable key
and block length of 128, 192 or 256 bits. It is believed to be
highly secure, efficient with low memory requirements.
By default, Blowfish is
the primary encryption algorithm used by EncryptIt. To switch to
Triple-DES or AES: select 3DES Algorithm or AES Algorithm
in the Options menu.
To switch back to Blowfish: select Blowfish Algorithm in the Options
menu.
