Cryptography in C# .NET
Explore the .NET Core options to encrypt and decrypt data
Description
In this course you will explore the .NET Core options to encrypt and decrypt data. After a brief history of cryptography, you will learn the difference between symmetric and asymmetric encryption and you will understand the details of AES. Next the .NET Core classes that are used to perform symmetric encryption are covered and used in the lab. Then you will learn the concepts behind asymmetric encryption and the details of RSA. Also the .NET Core classes that are needed to do asymmetric encryption are examined and used in the lab. Then you will learn what hashing is and how you can digitally sign documents. You'll also experience the use of certificates and how to use them in .NET Core.
This training uses language features until C# 10.0 and can be used with .NET Framework and .NET Core.
