Thanks for the updated patch! LGTM.

One minor comment: in v2 patch, it seems the encodings in the HINT message are
listed in the order they appear in the enclist struct. Wouldn't it be
clearer to list them
alphabetically, matching the order shown in the docs [1]: base64,
base64url, escape, and hex?
