Encrypt: Caesar's Method

The following is an example of how to mathematically encrypt a message.

We will be using the following table to encode our message:

A

B

C

D

E

F

G

H

I

J

K

L

M

N

O

P

Q

R

T

S

U

V

W

X

Y

Z

X

Y

Z

A

B

C

D

E

F

G

H

I

J

K

L

M

N

O

P

Q

R

S

T

U

V

W

Caesar's cipher is denoted as f(p) =(p+3) mod 26 where p is the integer number of the plain-text.

In this case the key is a shift of 3.

Message to be encoded: "I LOVE MATHEMATICS"

Caesar's cipher: "F ILYB JXPEBJXPFZQ"
