Introduction to Encryption Basics

Encryption is essential for securing modern digital communication and data. This beginner-friendly course introduces how data encryption algorithms and methods safeguard your identity and data security. You’ll explore how data is protected, learn key-to-encrypt principles, and understand how encryption key policies impact data stored across platforms—all through hands-on, accessible lessons.

You’ll explore hard- and software encryption, asymmetric and symmetric encryption, digital signatures, and digital certificates. Each topic is broken down clearly, with guided exercises that let you test, encrypt, and sign your own data.

• Encrypt data at rest with zip files and folder encryption tools
• Create encrypted messages with digital signature validation
• Use digital certificates for secure daily communication
• Understand data encryption standard and encryption algorithms
• Apply data encryption techniques and transport layer security
• See how data encryption works to protect overall data security

Confidently navigating the essentials of encryption means understanding how data flows between parties, how both the sender and receiver use a secret key in symmetric key systems, and how cryptographic hash functions verify integrity. 

You’ll learn how encryption and decryption work together to scramble data into unreadable formats and restore it only with the correct corresponding private key. By the end of the course, you’ll know how data is encrypted and protected across various tools and platforms, and be ready to apply these skills in real scenarios.
