misunderstood altogether. So we'll attempt in this article to answer some of the most commonly asked questions
What does encryption do for me?
Encryption and cryptographic software has been used in many different ways to make
systems more secure. There are some good and some not so good encryption programs, but we'll reccomend here only
two of better known encryption programs. This article discusses only a few ways that encryption software can make
your compyter system more secure, including:
1) Encrypting your
email - This will reduce the chances of someone
reading your email.
2) Encrypting your
files - To prevent others from accessing your business or personal files
(via spyware programs, for example).
To programs are mentioned that will help encrypt information. There are many more
programs out there that will help, but these programs are good and a good place to start as any. They have the
added benefit of both being free with source code available.
Will encryption stop people from accessing my information?
Encryption simply makes it harder for people to gain access to important information, like passwords or
sensitive information in a file. The first thing you should know about encryption is that the algorithm that is
used to encrypt can be simple or more complex and that affects how securely what you have encrypted is protected.

communications from being hacked into
Overall, encrypting your email or your files will not make them 100% secure or
hacker-proof. But it will make them much harder to break into and the very act of encryption will dissuade many

messages can be a magnet for determined hackers. You have to find a fine balance between protection your important
files and emails by encrypting them, and overdoing it by encrypting everything.
Why bother to encrypt my email?
It should be noted that email is far less secure than paper mail for two very good
reasons: first, electronic data can be accessed easily over an Internet and secondly, electronic data is really
simple to copy. There is a very good chance that someone has snooped around in your email despite your best
intentions to stop it.
By encrypting important emails, you will greatly reduce the chance of your
messages being read by someone else.

popular one and arguably the best encryption program is PGP (Pretty Good Privacy), or its Gnu offshoot

doesn't have: Privacy. It does this by encrypting your mail so that nobody but the intended person can read it.
When encrypted, the message looks like a meaningless jumble of random characters. PGP has proven itself quite
capable of resisting even the most sophisticated forms of analysis aimed at reading the encrypted
Why bother to encrypt my files?
The answer to this boils down to what you store on your computer. If you have
financial data with important information like social security numbers, email addresses, account numbers and
passwords, then you open yourself up to losing very valuable information. Most corporate Internet security
employees will attest to the widespread theft of very valuable information. As long as you are connected to the
Internet you are vulnerable.
In addition to encrypting your important files, be also creative in utilizing
other clever methods of "hiding" your files, or choosing generic names for them. And perhaps one of the best
precautions is to have your important files stored on a separate disk and never directly available on your
