Identifying simple encryption algorithms and functions
In this section, we will take a look at the simple encryption algorithms that are widely used in the wild. We will learn about the difference between symmetric and asymmetric encryption, and we will learn how to identify these encryption algorithms in the malware’s disassembled code.
Types of encryption algorithms
Encryption is the process of modifying data or information to make it unreadable or unusable without a secret key, which is only given to people who are expected to read the message. The difference between encoding or compression and encryption is that they do not use any key, and their main goal is not related to protecting the information or limiting access to it compared to encryption.
There are two basic types of encryption algorithms: symmetric and asymmetric (also called public-key algorithms). Let’s explore the differences between them:
- Symmetric algorithms: These types of algorithms...
