how to seralize openfhe binfhecontext

[bpradeep508]

from openfhe import *
import pickle5 as pickle

Sample Program: Step 1: Set CryptoContext

cc = BinFHEContext()
file_name = 'std1.pkl'

Writing the student object to a file using pickle

with open(file_name, 'wb') as file:
pickle.dump(cc, file,protocol=pickle.HIGHEST_PROTOCOL)
print(f'Object successfully saved to "{file_name}"')

seems like we need to implement https://pybind11.readthedocs.io/en/latest/advanced/classes.html#pickling-support

Could you explain @bpradeep508 why you need this feature ?

[bpradeep508]

Distributed environment computation going on different nodes. So bininfhe context needed to be shared among the nodes for computation.

Thanks. So you need to really specify what attributes of the FHE Context you need to serialize and thats enough to deserialize;
how do you currently check the equality of the two FHE Context ? Maybe that is a good enough test to know if the ser-des approach is working or not. Please share it

how do you currently check the equality of the two FHE Context ? c ++ version already available. we need same for python binfhe context

currently equality is reflexive: a = a tautological

[arcturusannamalai]

the key members of binfhecontext are in form of a binary large object (BLOB) and need to be serialized/deserialized; this can't be done easily without more support from the upstream C++ API
