Is this a BUG REPORT or FEATURE REQUEST?:
Feature Request

What happened:
We have our own blockchain, and We are using Alice to generate MPC Shares needed for signatures for different blockchains (BTC, ETH). Currently we can smoothly generate Signatures on non-encrypted transaction data.
But our Transaction data would be actually be in an encrypted form for Production release and therein lies our blocker.

What you expected to happen:
We are trying to achieve the same result when generating Signatures for encrypted transaction data.
Any support or direction along these lines would be really helpful.

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:
