In my opinion cryptography is one of the most interesting topics of the course and it is something that I already had a relationship with last semester in my subject of computational mathematics. My teacher explained some of the methods used and used for encryption of information and told us a lot about the Turing machine, which although used to solve algorithms was a key element in the Second World War to encrypt intercepted data . I could also see the Cesar cipher, used for a long time and actually very simple. Nowadays it is necessary to keep all information secure and cryptography must be essential to keep all the information we trust to the websites that we access safely.
In the semester, the school will provide important information about teachers and students and it is necessary to look for a tool that allows us to encrypt this data to keep them safe. As we will use NodeJS we will have to adapt a tool that allows us to use them and return the information as JsonWebTokens
