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.

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.
