Exam Ref 70-483: Programming in C#

Objective 3.2 Perform symmetric and asymmetric encryption

Security and cryptography are closely related to each other. Some important steps in building a secure application are the authentication of users, making sure your data stays confidential, and ensuring that no one can tamper with your data. The .NET Framework offers several implementations of popular algorithms that you can use to protect your applications.

This objective covers how to:

• Use symmetric and asymmetric encryption algorithms.

• Work with encryption in the .NET Framework.

• Use hashing.

• Manage and create certificates.

• Use the code access permissions from the System.Security namespace.

• Secure string data.
