Testing the addition of ciphertexts

[iammrgenie]

Hi,

Thanks for your library. I am trying to test the ciphertext addition function. However, when I try to decrypt the resulting ciphertext, I get 0. The decryption of a single ciphertext works fine. Do you happen to have tested this?

Hi,

Yes it should work.

Hi, I got the same problem with you when doing gamal_add(). It is because the the function from openssl EC_POINT_Add() in gamal_add() return 0 (an error). Almost 2 years passed, may I ask if you have any solution to this?

Thank you so much!
