Caesar Ciphers are very simple methods of encryption because the work by shifting the alphabet over a few characters and matching up the letters (see the picture above)—in fact, if you've ever ...

Someone who knows you are using a Caesar Cipher encryption could easily break it by hand, since there are only 26 possibilities. In later posts, we will write more secure encryption algorithms.

As discussed above, however, although the Caesar cipher provides a great introduction to cryptography, in the computer age it is no longer a secure way to send encrypted communications electronically.
