👉 Reverse engineering is the process of deconstructing a complex system, product, or software to understand its underlying structure, functionality, and design principles, often with the goal of replicating or improving upon it. This involves analyzing the components, algorithms, and interactions within the system to extract valuable insights that can be used for various purposes, such as creating compatible alternatives, enhancing performance, or identifying vulnerabilities. In software engineering, reverse engineering can be applied to legacy systems to document their behavior and facilitate maintenance or migration. It requires a deep understanding of both the original system and the target application to ensure accurate and effective replication or adaptation.
