About Encryption and Making Your System Secure
What does encryption do for me?

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

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. Encryption
systems have been broken when the method of encryption is

computer. If you have financial data with important

very valuable information. As long as you are connected to
the Internet you are vulnerable.
