TFHE is a C++ library implementing fast fully homomorphic encryption over the torus, based on the CGGI16 scheme with gate-by-gate bootstrapping. It evaluates binary gates on encrypted data at roughly 13ms per gate per core, achieving at least 110-bit security.

Use cases

• evaluate boolean circuits on encrypted data without decryption
• build privacy-preserving cloud computation applications
• experiment with fully homomorphic encryption research
• perform homomorphic gate-by-gate bootstrapping
• compute on ciphertexts with no gate count restrictions

When to choose

• you need fast bootstrapped homomorphic evaluation of binary gates in C/C++
• you want the original TFHE scheme with low-level control over circuits
• you need 110-bit security homomorphic encryption on Linux or macOS

When to avoid

• you need a higher-level API or programmable bootstrapping - use TFHE-rs instead
• you need integer or string homomorphic operations rather than boolean gates
• you need Windows support or compilers other than g++/clang
