I see a problem in the otherwise sound idea: dormant retroviruses. It is known
that some viruses insert their genomes into our genome, and would be encrypted
along with the rest. They usually lie dormant until certain conditions are
met, and then become active. We might need to scan the genome before encrypting
it, to remove threats like this.
