Encrypt embeddings in cache

[morgante]

In my reading of the source code, it looks like vector embeddings are not currently encrypted. This is potentially problematic, since they are (somewhat) reversible.

Would you be open to a pull request to encrypt content using the input, so it's only retrievable when you have access to the original source text?

Hi @morgante of course - are you still interested in adding this?

I ended up implementing this with Braintrust instead: braintrustdata/braintrust-proxy#46

Still highly recommend you add encryption, but currently not planning to use Helicone.
