It turns out that the encryption it uses is just a few baby steps beyond a basic Caesar Cipher. A Caesar Cipher just shifts data by a numeric value. The value is the cipher key.

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 ...

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.

Giovan Battista Bellaso, a 16th-century cryptologist, designed the Vigenere cipher (falsely attributed to diplomat Blaise de Vigenere), believed to be the first cipher that used an encryption key.

Mysterious cryptic code suddenly appeared on the Internet in January 2012Cicada 3301"Attracts the interests of programmers and hackers all over the world. Although a lot of people got on reading ...

Some ciphers have simple keys, others, complex ones. The key for a cipher used by Augustus Caesar, some 2,000 years ago, was simple enough: The receiver just had to shift the alphabet one position.

Bernard claims Lukas uses a Ceaser shift cipher to decode the meaning of Salvador Quinn's cryptic message, making it hard not to wonder what it means.
