On: Launch HN: Blyss (YC W23) – Homomorphic encryption as a service

[dougk16]

Let's say I sent up a key "foo" to get the value "bar", and I did this again and again. Will either "foo" or "bar" be encrypted to the same ciphertext again and again? Or is there some kind of nonce or salt or other mechanism that will make the ciphertext always different? Congrats on launching and thank you for any answer.

Great question! The ciphertexts will be different every time, just like in standard encryption; the scheme uses something very similar to a nonce.
