pickle Serialization and Deserialization¶pickle module can serialize objects into in a Python-specific data formatpickle:“Pickle files can be hacked. If you receive a raw pickle file over the network, don’t trust it! It could have malicious code in it, that would run arbitrary Python when you try to de-pickle it. However, if you are doing your own pickle writing and reading, you’re safe (provided no one else has access to the pickle file, of course.)”
“Pickle is a protocol which allows the serialization of arbitrarily complex Python objects. As such, it is specific to Python and cannot be used to communicate with applications written in other languages. It is also insecure by default: deserializing pickle data coming from an untrusted source can execute arbitrary code, if the data was crafted by a skilled attacker.”
pickle, but it’s been used for many years, so you’re likely to encounter it in legacy code—old code that’s often no longer supported. ©1992–2020 by Pearson Education, Inc. All Rights Reserved.
