You may have a need, you may not, or you may just want to know how to secure text in its most easiest form with out the use of having to be a cryptographer but still wanting to be cryptologic with your text.
A difference between CODE and CIPHER.
What this book wishes to demonstrate, is really CODE rather than a pure CIPHER.
This is a basic form of CODE which can be seen as acting as a deterrent to anyone looking on who is unfamiliar with the coded characters, numbers and letters.
It may be a Facebook update, it could be an entire book or novel, what ever the cause for the CODE, let it be!
It does not matter if it is small or CAPS the text to be coded, as the code is applied for both sizes of text irrespective of if it is small or CAPS.
THIS CODE IS FOR THE ENGLISH ALPHABET ONLY!
