Hi,

I’m using OpenFHE with the BFV scheme in Python. I serialize a ciphertext with `Serialize(ct, BINARY)`, send it over the network as base64, then decode it back to bytes.

Is there a way to call `DeserializeCiphertext()` with a byte string directly? The function seems to only accept a file path.

Thanks!

Yes you can use this function:

```python
DeserializeCiphertextString(serialized_ciph, BINARY)

```

Event though this is not present in the documentation, you can check its usage in this file [here](https://github.com/openfheorg/openfhe-python/blob/07a81b4bf1d84aa96a70de31dadce2d0ae19591c/tests/test_serial_cc.py#L138)

Thank you very much!
