Did you know that even the great Caesar used a cipher to hide his military
correspondence between 100 – 44 B.C? The key in this case was simply
to shift to the right by three.
Encryption is not a new concept but it keeps getting more and more complex and useful. We thought that a guide to encryption accessible to everyone would be more than welcomed, either to understand it better or to share it with people who would need it.
Just a short intro: encryption is the process through which information or data is transformed (encoded) in such a way that is unreadable to anyone who does not have the knowledge of the way it was transformed.
The information thus becomes available only to the authorized parties. This authorization works based on keys. Encoding the information is made by using an encryption key while decoding the information is made by using a decryption key.
You can read the entire guide here.
