deszerializálással

Deserialization, often referred to as "deszerializálással" in some contexts, is the process of transforming data that has been serialized into a format suitable for transmission or storage back into its original object-oriented form. Serialization is the act of converting an object or data structure into a format that can be easily saved or transmitted, such as a byte stream or a string. Deserialization is the inverse operation, reconstructing the object from that serialized representation.

This process is crucial for many software applications. For example, when an application saves its state to a file, it serializes the relevant data. Later, when the application reloads, it deserializes that data to restore its previous state. Similarly, in network communication, data is often serialized before being sent across the network and then deserialized by the receiving application. Common serialization formats include JSON, XML, Protocol Buffers, and various binary formats. The choice of format impacts factors like efficiency, readability, and language interoperability.

A significant security concern associated with deserialization is deserialization vulnerabilities. If an attacker can control the serialized data that an application deserializes, they might be able to inject malicious code or manipulate the application's behavior. This is because the deserialization process can sometimes execute arbitrary code embedded within the serialized data. Therefore, it is essential to carefully validate and sanitize any data that is being deserialized, especially when it originates from untrusted sources. Many programming languages and frameworks provide mechanisms for deserialization, and secure coding practices are vital to prevent these types of attacks.
