Caesar cipher is a simple substitution cipher where each letter in the plain text is replaced with a letter a fixed number of places down the aplhabet.
EXAMPLE
If the number of places to shift is 3, the letter A would be converted to ltter D. Using the same number of shifts the letter x wud be replaced with letter a. if we change the number of shift to 2 A wud be C and X wud be Z.
Using the shift of 3 for the plin text below
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.
Will result in the following cipher text
WKH TXLFN EURZQ IRA MXPSV RYHU WKH ODCB GRJ.
