Información sobre este eBook
Imagine having a job that has been around for thousands of years. People called cryptologists have been making—and breaking—codes almost as long as humans have written things down. Read about the historical code makers and breakers who protected their countries by coding and decoding messages for their governments, and the modern cryptologists who keep emails, texts, and online purchases secure.
