Function gnunet_sys::GNUNET_CRYPTO_paillier_hom_add

pub unsafe extern "C" fn GNUNET_CRYPTO_paillier_hom_add(
    public_key: *const GNUNET_CRYPTO_PaillierPublicKey, 
    c1: *const GNUNET_CRYPTO_PaillierCiphertext,

) -> c_int

Compute a ciphertext that represents the sum of the plaintext in @a x1 and @a x2

Note that this operation can only be done a finite number of times before an overflow occurs.

@param public_key Public key to use for encryption. @param c1 Paillier cipher text. @param c2 Paillier cipher text. @param[out] result Result of the homomorphic operation. @return #GNUNET_OK if the result could be computed, #GNUNET_SYSERR if no more homomorphic operations are remaining.
