Hi!  
I’m exploring the opportunity of using Noir for an experiment. I’m wondering if there is any available gadget containing the primitives to perform:  
a) symmetric key encryption (no particular preference for a specific scheme)  
b) asymmetric key encryption (no particular preference for a specific scheme)

We have a few [hashing primitives](https://github.com/noir-lang/noir/blob/master/noir_stdlib/src/) available but not encryption specifically atm.

How does the workflow of your experiment look like?

The component that regards encryption would be to:

- prove that a value committed is equal to a secret being encrypted with a symmetric key
- prove that a (different) value committed is equal to a secret being encrypted with an asymmetric key (public key)

Would proving `hash(secret, ...)` + sharing the preimage with the decryptor sufficiently mimics what you aim to achieve, or must it strictly be an en/decryption scheme?

Thanks for the reply. Actually from what I can tell, it must be an encryption/decryption scheme.

Do you have a library that contains all these reusable primitives? Would it be something worth adding to it?

We don’t currently have such a library. Would you be interested in creating one? We’d be happy to help with technical and financial support via our grants program. You can learn more about it here.
