First off, welcome to the community! Next, might I understand better your goal here? Doing import/export of binary data with python is a python question and that can be done a number of ways. If you're moving a DLL's binary image around, that's very different than an encrypted picture, right? And in all that, there's what's optimal vs. "easy". But, given this is a Neo4j community, I want to make sure I'm answering the question you have and binary data is usually not a part of the graphista solution area. Links to binary data, etc., are. But let me start with getting a better handle on the question. thanks for that.
