Checkout the PALISADE library. (Full disclosure - I'm one of the main people behind the library.) PALISADE is an active open-source project partially funded by DARPA, IARPA and Sloan Foundation. It has an active user community that includes academics, start-ups and large defense contractors. A new version of PALISADE was just released yesterday. It supports the current major HE schemes (BFV/FV, BGV/BV, etc...) along with modules for different kinds of Gaussian sampling, and lattice crypto building blocks. https://git.njit.edu/palisade/PALISADE https://git.njit.edu/palisade/PALISADE
