To encrypt a message: 1. Green-flag 2. Enter your password 4 times. (Has to be a number value. NO fractions. Can be different every time.) 3. Enter your, "Secret" message. 4. Ta-da! Be sure to press, "a" key to save that password for later. To Decrypt Code: 1. Space-bar 2. Option #1 press enter to use saved password from earlier. 3. Option #2 enter anything in, press enter, then type your password.
Mathematics involving 2x2 Matrixes. It work on a simple algebraic equation. P * M = C (Password, Message, Code) So to reverse the process. M = C / P. However, dividing with Matrixes in impossible but I use the inverse property as a workaround. Ex. 10 * 1/10 = 1 P (1/P) M = C (1/P) ---> 1 * M = C * 1/P It is possible to expand on this idea (bigger dimension matrixes, multi-step equation, or multi-key matrixes) The list could go on to make it even more secure. BUT it would take a lot more effort to make, not to mention the debugging process... This is just the basic for simple use.
