Paillier Cryptosystem

Package paillier contains Paillier's cryptosystem (1999). All routines here from pseudocode §2.5. Fig 1: The Paillier Cryptosystem.

This module provides APIs for:

• generating a safe keypair
• encryption and decryption
• adding two encrypted values, Enc(a) and Enc(b), and obtaining Enc(a + b), and
• multiplying a plain value, a, and an encrypted value Enc(b), and obtaining Enc(a * b).

The encrypted values are represented as big.Int and are serializable. This module also provides JSON serialization for the PublicKey and the SecretKey.
