Manual básico de criptología

Are you one of those who unlocks your mobile using your fingerprint or facial recognition? Of those that you buy using your bank card on the internet or with contactless technology in establishments?. Have you ever wondered what it means when some messaging platforms encrypt your messages end-to-end? Information security is increasingly important in our hyper-connected lives, but we are not always aware of it or know how mechanisms that can be very convenient to use, but overwhelmingly complex to understand, work. "Basic Manual of Cryptology" is an accessible volume with which to delve into the fascinating world of information encryption at the hands of the renowned cryptologist and mathematician Luis Hernández Encinas. With an entertaining and didactic style, we will immerse ourselves in a journey through the history of cryptography: from the Scytal used by the Greeks and Romans, the Polybius table, the Alberti disks or the various encryption methods used by kings, queens, Templars or Freemasons to keep their messages away from prying eyes, to the Enigma machine used during World War II by the Germans to send encrypted messages and decrypted by the Allies with the help of Alan Turing. And not only that, we will also delve into current security methods, such as online finance, credit card payments or cryptocurrencies and "blockchain" technology. An essential book for those interested in information security and its history. With his experience and knowledge, the author provides readers with a clear and accessible guide to understand the evolution of cryptography and its infinite uses in today's world.
