Abstract
Before the invention of computers all cryptographic methods were calculated manually, and as such the cryptographic methods developed during that period took into account this limitation. The Caesar Cipher method was one of the first to be used and disseminated in several countries. This method is very simple, which implies that with current means you can break your security quickly and easily. However, it has a characteristic that, given its nature, any change in the method increases its safety, and like other authors in this article, it will be shown that a small change will imply some improvement in the method's safety.
Keywords
