binFHE

• Boolean arithmetic, comparisons, and aribtrary function evaluation based on DM and CGGI schemes

core

• underlying implementation providing the base that binFHE and pke are built off of

pke

• integer and real-number arithmetic based on BGV, BFV, and CKKS schemes

Warning

Although the OpenFHE team has provided various utility functions to make OpenFHE accessible to non-cryptographers, it is still necessary for the end-users to carefully consider how they are using the code. Improper use can result in leaked information. Use of OpenFHE in production environments should be reviewed by homomorphic encryption experts.

Additionally, see our Security Considerations for considerations that should be taken into account in your work.
