Deserialization techniques refer to the methods used to convert serialized data back into its original object or data structure. Serialization is the process of transforming an object into a format that can be stored or transmitted, such as a byte stream, JSON, or XML. Deserialization is the reverse process.

Common deserialization techniques often involve parsing the serialized data according to its format. For JSON, parsers interpret key-value pairs and nested structures to reconstruct objects. XML deserialization follows a similar pattern, using parsers to map XML elements and attributes to program objects. Binary serialization formats, like Protocol Buffers or Avro, require specific parsers designed to understand their compact binary encodings.

The choice of deserialization technique depends heavily on the serialization format used. It's crucial that the deserializer understands the exact structure and encoding of the serialized data to avoid errors or data corruption. In many programming languages, libraries provide built-in support for deserializing common formats, simplifying the process for developers.

Security is a significant consideration in deserialization. Untrusted serialized data can pose risks, as deserializing malicious input can lead to arbitrary code execution or denial-of-service attacks. Therefore, careful validation and sanitization of deserialized data are essential, especially when dealing with data from external or untrusted sources. Secure deserialization often involves using allowlists of trusted types or employing safer data formats.
