Securing Blockchain Networks like Ethereum and Hyperledger Fabric

Simple encryption example

Among the simplest examples of encryption algorithms, we can find the Caesar algorithm. Caesar's algorithm is an example of a substitution cipher, meaning that another character is substituted for a given character, respecting a certain coding rule in the substitution of the different characters.

In the following screenshot, we have reproduced one of the possible substitutions for letters of the alphabet. For our example, we'll choose the substitution that moves the original letter 12 positions to the right.

In this way, the letter A will correspond to the letter M, the letter B to the letter N, and so on:
