https://api.twinstake.io/v2/staking/ethereum/exit/key
This endpoint allows a GPG public key to be associated with an entity filter, and for all exit messages of that entity filter to be encrypted with it. This endpoint must be called before exit messages can be obtained from GET /v2/staking/ethereum/exit-messages.
If a subsequent GPG key is associated with an entity_filter then exit messages will only be able to be decrypted with the last uploaded GPG key.
