But that doesn't meet the requirement. If the answer is encrypted, I can't verify that you actually KNOW the answer and didn't just encrypt a random string with a random key. Think about why kidnappers send photos of the victim holding a copy of today's newspaper - they do a good job of proving the kidnappers have a live victim (at least as of when the paper went to press), but don't give you any info about *where* they have the victim.
