szerializáció

Szerializáció is the process of converting a data structure or object state into a format that can be stored (for example, in a file or database) or transmitted (for example, across a network connection) and reconstructed later in the same or a different computer environment. The term "serialization" is typically used when the data is structured, and "marshalling" is often used when dealing with remote procedure calls. The reverse process, extracting data structure from that format, is called deserialization or unmarshalling.

Serialization is often used for:

* Persistence: Saving the state of an object to a file or database so it can be restored later.

* Inter-process communication (IPC): Sending data between different processes, even on different machines.

* Deep copying: Creating a completely independent copy of an object by serializing and then deserializing it.

Various serialization formats exist, including JSON (JavaScript Object Notation), XML (Extensible Markup Language), Protocol Buffers, and binary formats specific to programming languages (like Java serialization or Python's pickle module). The choice of format often depends on factors such as readability, performance, size, and interoperability requirements.

Deserialization is the process of reconstructing the original data structure or object from its serialized representation. It's crucial that the deserialization process can correctly interpret the serialized data to recreate the object with its original state. Security is a significant concern during deserialization, as maliciously crafted serialized data can lead to vulnerabilities such as code injection or denial-of-service attacks. Therefore, deserializing data from untrusted sources requires careful validation and sanitization.
