from github:
“This is currently an exploratory proof-of-concept. While it could be deployed in practice, the run-times of the FHE-C++ operations are likely to be too long to be practical at this time. This transpiler heavily relies on the TFHE library for security guarantees. Since TFHE is relatively new, there are yet to be robust cryptanalyses of TFHE. Thus, before including this library in a live production deployment, be aware that there may be yet undiscovered vulnerabilities in TFHE.”
