Lightweight Partially Homomorphic Encryption Library for Python

LightPHE is a lightweight partially homomorphic encryption library for Python. It is a hybrid homomorphic encryption library wrapping many schemes such as RSA, ElGamal, Paillier, and more. It offers a more efficient and practical choice compared to fully homomorphic encryption for tasks that demand partial homomorphic capabilities, being faster, demanding fewer computational resources, and generating smaller ciphertexts. The library is actively maintained, with its latest release in March 2026.
