Example we are going to encrypt this "POGI NI BENG".
So we need a key and the key that we are going to use is the date today "January 1-2018" then we are going to convert it into numbers. So it will be like this "01-01-18" or "01-01-2018" but I am going to use "01-01-18"
After we convert it, we are going to put the key under the message, so it will be like this;

P O G I N I B E N G
0 1 0 1 1 8 0 1 0 1

NOTE: the numbers under the message indicates the number of shift and the shifting is either backward or forward
so ito na; (forward shift ginamit ko)

P - P (magiging P parin siya kasi 0 yung number sa ilalim)
O - P
G - G
I - J
N - O
I - Q
B - B
E - F
N - N
G - H
