Python implementation of the Fully Homomorphic Encryption (FHE) scheme TFHE: Fast Fully Homomorphic Encryption over the Torus.

You can see example usages in the Jupyter Notebook and the tests directory.

The starting point of this implementation was the code written by NuCypher for their NuFHE library. More specifically the code in commit 17f3b62 was used which itself seems to be a port of their Julia version nucypher/TFHE.jl which looks like a port (see this commit) of the original tfhe/tfhe codebase that's written in C / C++.
