pi-HEaaN is a Python library designed to simulate HEAAN (Homomorphic Encryption for Arithmetic of Approximate Numbers), enabling users to experiment with HE (homomorphic encryption) concepts and workflows. It serves as an environment for exploring approximate-number homomorphic encryption without requiring a full production deployment of the underlying scheme.

The library supports fundamental cryptographic functions, including key generation, encryption, and decryption. In addition, it implements core homomorphic operations, such as homomorphic addition and homomorphic multiplication, allowing arithmetic to be performed directly on encrypted data.
