How Encryption Works.

This is a small scale illustration of what happens when a file becomes encrypted.


Here is a small file
consisting of 100 of the one character.
no
Except for the number 6 in the 21st place.
It might be a useless file, but it serves well as our example. This is called "Plain Text"
 
If you were to look at how this file is stored on your hard drive, you would see the following:
no
This shows that each character is represented by a Hexadecimal value. The Hex value for 1 is "31"; the Hex value for 6 is "36". These Hex values are what actually get converted with our Encryption program.

Now if we Encrypt the file, "hundred Ones.txt" with Away RJN Cryptography and then reopen it in NotePad or any other Word Processor, we would see this. Notice that the name of the file is now hundredOnes.AAA. The AAA on the end tells you that the file is Encrypted.
no
It has been turned into gibberish called "Cipher Text"! The important thing is that it looks totally random. It also seems to be longer. And it is. Because embedded in that string of characters is the name of the file, the Nonce used (See Rijndael AES) and the length of the File Name.

Here is what the Hex values of this file look like on your hard drive:
no
You can see the first letter Z is represented by Hex value "5a". Hex values are two digit numbers made from these numbers and letters:0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f. So you can have Hex values like 10, 1a, 9a, aa etc. For a complete explanation of Hex numbers go here.

That's all there is to it.
The only problem is that to get from Plain Text to Cipher Text takes a fair amount of computing and, to do it right, an enormous amount of brain power to develop the Encryption Algorithm that can't be cracked. The Rijndael Encryption Algorithm as implemented in Away RJN Cryptography is the means to accomplish that. The encryption algorithm used in Away RJN Cryptography is cipher security that is virtually unbreakable.

For Windows 7, 8, 8.1 and  10.
This is not Backward compatible with Previous versions of Away RJN Cryptography
Runs on 64-bit machines with no problem.
Each of these are one-time charges.
