WitrynaPaillier encryption is only defined for non-negative integers less than PaillierPublicKey.n. Since we frequently want to use signed integers and/or floating point numbers (luxury!), values should be encoded as a valid integer before encryption. The operations of addition and multiplication [1] must be preserved under this encoding. Namely:
