Abstract: It is said that all things in our universe are linked and even a small disturbance at one point will reverberate and affect all other constituent elements. This statement may be refuted in the real world, but is becoming valid in the virtual world where most activities can be watched by others linked to the Web. One solution used to stop internet intruders from reading messages, credit cards and files is encryption. Encryption is the altering of original information using various techniques and transmitting that data for decryption. A problem with file encryption is that a hacker who is able to access an encrypted file will get enough indication the file is encrypted to trigger his curiosity to discover the real information. If a file is intercepted by a skilled hacker all the effort to encrypt the file is useless. * Data needs to be transmitted in such a way that it prevents others from reading it directly.
