- Caesar cipher is substitution technique cipher
- In Caesar cipher we replace each alphabet with the alphabet that is actually 3 alphabet down the order. So, each A will replace with D, B will replace with E, C will replace with F and so on.
- Thus using Caesar cipher MY BSC IT will replace with PB EVF LW.
- Clearly we can see that Caesar cipher is weak cipher for hiding plain-text messages. All that required to break this cipher is to do reverse the Caesar cipher that is replacing each alphabet with 3 places up in the line.
- Process mention above will reveal original text so one can easily figure out PB EVF LW is actually MY BSC IT.
