Course description

When considering a multilayer strategy for protecting user data, you should always start with the data itself. Encryption protects data whether it is at rest, in transit or in use. In this course, you will learn about the Android file system, how and where data can be saved and how to protect that data wherever it is found. You will examine a common mistake developers make when handling user credentials and other secrets. You will learn how to encrypt and validate user credentials in your app, ensuring that at an app level they are difficult to compromise. You will then learn how to leverage Android Keystore to safely store and retrieve credentials.
