Basic Encryption Methods

1. Basic Encryption Methods

Now more than ever, encryption has become central to security and privacy, helping protect the data of individuals and corporations alike. In this lesson, we'll learn what exactly encryption is, basic encryption methods and the qualities of strong encryption.

What is Advanced Encryption Standard (AES)? - Definition & Overview

2. What is Advanced Encryption Standard (AES)? - Definition & Overview

In this lesson, we'll take a look at the Advanced Encryption Standard (AES), its purpose, its basic characteristics, and its strength. At the end of this lesson, you should have a good understanding of the fundamentals of this technology.

What is The Data Encryption Standard (DES)?

3. What is The Data Encryption Standard (DES)?

The Data Encryption Standard (DES) is a pioneering encryption algorithm that helped revolutionize encryption. In this lesson, we'll come to understand the current and historic significance of the Data Encryption Standard, and look at two basic encryption methods.

Symmetric Encryption: Definition & Example

4. Symmetric Encryption: Definition & Example

This lesson will cover symmetric encryption, a well-known standard for data encryption. It is a shared-key methodology, meaning the key used to encrypt the data is the same key used to decrypt it. Data Encryption Standard (DES) is also explained.

RSA Algorithm: Encryption & Example

5. RSA Algorithm: Encryption & Example

With the ever increasing instances of Internet-based commerce, it makes sense that protecting those transactions will become more and more important. In this lesson, we'll take a look at a commonly used algorithm, RSA, how it works, and where it is used.

IPsec vs. SSL

6. IPsec vs. SSL

This lesson will cover two encryption methods used to secure data: IPSec and SSL. These methods are mainly used to allow connections to secure networks from otherwise insecure sources.

HTTPS Encryption

7. HTTPS Encryption

With the rise of the Internet, it makes sense that there would be those out there that want to take advantage. Some at the expense of others. In this lesson, we'll take a look at a technology that is helping to keep us safe - HTTPS.

WPA vs. WPA2 Encryption

8. WPA vs. WPA2 Encryption

Explore how your router is protected from prying eyes and the hands of hackers. WPA and WPA2 are both methods to implement to block unsanctioned visitors from accessing your computer. Let's investigate their differences.

WPA vs. WEP Encryption

9. WPA vs. WEP Encryption

Explore how to protect your router and keep unauthorized attackers from gaining access to your internet and Wi-Fi with encryption methods WEP and WPA.

VPN Encryption: Types & Protocols

10. VPN Encryption: Types & Protocols

VPN (Virtual Private Network) encryption is used to ensure secure communications over data networks. In this lesson, we'll look at some of the different protocols that make up a VPN and the types of encryption that are used within a VPN.

Public Key Encryption: Definition & Example

11. Public Key Encryption: Definition & Example

Protecting information transfers and e-commerce transactions is of vital importance these days. And with the ever-increasing number, that is sure to continue. In this lesson, we'll take a look at commonly use method, public key encryption, and how it works.

SSH Proxy Tunnels

12. SSH Proxy Tunnels

In this lesson, we will examine what proxy tunneling is all about and understand what SSH proxy tunneling is. We will examine the three main uses of SSH proxy tunnels.
