## Feature request
A `rerandomise` and `rerandomise_with` methods to rerandomise a ciphertext
### Why?
To easily rerandomise ciphertexts.
### Alternatives
I'm not experienced and I'm ha…

We might want to eventually support "compressed" encryption, where instead using the whole random "a" polynomial, you just provide the seed for "a" and what PRNG to use. This gives a nearly free 2x re…

I wrote a simple test for AES128. But the operation result is wrong
`func TestAESGCMCircuit(t *testing.T) {
source := rand.NewSource(time.Now().UnixNano())
rand := rand.New(source)
privKey,…

Hi,
I want to fully utilize the channel slots in a single ciphertext during my computation. Is it possible to have more data encrypted into a ciphertext. for example, I have a ciphertext [1, 2, 3,…

Currently, `SaberCiphertext` can only be constructed from `from_bytes`, which requires a `[u8; Self::LEN]`. This requires a ciphertext to be copied before it is decapsulated. This is entirely unnecess…

Testing was done in the mock election live during DEFCON32.
If you intercept your POST request to the /api/submit-vote endpoint after you've made your selections, you can just resend the same cip…

I tried using the original SEAL library, which defines a data() function in the Ciphertext class that returns the coefficients of the ciphertext. However, I saw in "wrapper.cpp" that SEAL-Python does …
