B - X
C - S
D - F
E - Z, 7, 2, 1
F - E
G - H
H - C
I - V, 3
J - I
K - T
L - P
M - G
N - A, 5
O - Q, 0
P - L
Q - K
R - J
S - R, 4
T - U, 6
U - O
V - W
W - M
X - Y
Y - B
Z - N
EXAMPLE:
PLAINTEXT: detective codes
Using the ciphertext alphabet below, ieencrypt na natin yung plaintext. First is the letter D, we are going to look for letter D in the top row of the ciphertext alphabet then replace it with the letter below it, which is the letter F.
The second letter is the letter E, hanapin ulit natin siya top row ng ciphertext alphabet. As you can see, marami ang choices below it. So, just choose any of the given choices. But in my example, I chose the number 1 to encrypt letter E. And so on...
