Mastering data protection technologies

It is difficult to master all the technologies that exist concerning data protection. It is furthermore, a field that is in constant flux as new vulnerabilities are found. By choosing a good underlying foundation for your project, such as XMPP, you get a technology that helps you with many of the underlying risks — but not all. You will still need to understand the basics of data protection and cyber security. To cover this field meaningfully would require multiple books and is beyond the scope of this book. In this chapter, however, you will be presented by a very brief overview of technologies you should be familiar with, to the point of knowing how they work, what problems they solve, and when to use them.

Skimming the basics of encryption

Encryption algorithms are often divided into symmetric and asymmetric ciphers. Encryption algorithms often use multiple algorithms together to achieve the expected properties. Such ciphers are called hybrid. But...
