Just last week, global shipping giant maersk and ibm announced plans to joint venture on a trade platform intended to decentralize the global supply chain. On a symmetric key that also use a public key. A key, by contrast, is intended for use by the software that is implementing the cryptographic algorithm, and so human readability etc. When you step into a private voting booth, you can vote as you please.
