Generate a new Paillier key pair

Generates two random primes of modulus_bits / 2 bits each, forms the modulus, and returns a PaillierKeyPair containing the matching public and private keys.

Usage

paillier_keypair(modulus_bits)

Arguments

modulus_bits

modulus length in bits (e.g. 1024 or 2048).

Value

a PaillierKeyPair.

Examples

keys <- paillier_keypair(1024)
ct   <- encrypt(keys@pubkey, gmp::as.bigz(42))
ct
#> <PaillierCiphertext> (under 1024-bit key)

## Only the private key recovers the cleartext:
decrypt(get_private_key(keys), ct)
#> Big Integer ('bigz') :
#> [1] 42
