Data transmissions are vital and became
a necessity nowadays. Whether you
exchange private messages,
or business / commercial secrets,
you must protect your confidential
information from hackers, your boss, or
secret services using
Why use cryptographic software ?
We live in an insecure world where
unwanted persons can access your
personal information ( like e-mails or
personal desktop documents ) and often
use it against you.
Encryption pre-dates the Internet by
thousands of years. Going back in time,
Julius Caesar was an early user of
cryptography. He sent messages to his
troops using a secret code: a letter in
the alphabet was replaced by one say 5
positions to the right. So, an "A"
became an "E", "B"
became "F" and so on.
For example the word RETURN
would become VJYZVS.
The downside of this practice, this
cipher can be easily broken by either
figuring out a pattern, by brute force
or by getting ones hands on a plaintext
and ciphertext combination to deduce the
Encryption is the translation of data
into a secret code. To read an encrypted
file, you must know the correct password
(also called key) that allows you to
decrypt it. Encryption is based on
encryption algorithms - a process
capable of translating data into a
