Deserialization is the process of transforming data that has been stored or transmitted in a serialized format back into its original object or data structure. Serialization is the conversion of an object into a sequence of bytes or a string that can be easily stored, transmitted, or reconstructed. Deserialization is the inverse operation, taking those bytes or strings and recreating the original object in memory.

This process is fundamental in many areas of software development. For instance, when you send data across a network, like in a web API request, the data is often serialized into a format like JSON or XML. The receiving application then deserializes this data to work with it as native objects. Similarly, when data is saved to a file or a database, it might be serialized, and later deserialized when retrieved.

Common serialization formats include JSON, XML, Protocol Buffers, and MessagePack. Each format has its own advantages and disadvantages regarding readability, performance, and data size. The choice of format often depends on the specific use case and the programming languages involved.

A critical aspect of deserialization is security. If an attacker can control the serialized data being deserialized, they might be able to exploit vulnerabilities in the deserialization process to execute arbitrary code on the target system. This is often referred to as deserialization vulnerabilities or insecure deserialization. Therefore, it is crucial to ensure that data being deserialized comes from trusted sources or that the deserialization process is implemented securely, often by validating the incoming data before deserializing it.
