Cryptography Essentials in C#
A practical guide to encryption, hashing, and digital signatures in C#
Description
From ancient secrets to modern digital security, cryptography is the art and science of protecting information. This course takes you on a journey through its core principles, starting with a glimpse into historical ciphers and the brilliant minds that shaped the field. We'll unravel the fundamental differences between symmetric and asymmetric encryption, the two pillars of modern data protection.
You'll explore the .NET cryptography APIs and learn to implement widely-used algorithms like AES for symmetric encryption and RSA for asymmetric encryption. We'll also cover how to ensure data integrity with hashing and digital signatures, and how to establish trust using digital certificates. Through hands-on labs, you will apply these concepts to build secure C# applications, turning theory into practical skill.
This training uses language features until C# 10.0 and can be used with .NET Framework and .NET Core.
