PackageKey class

One public key advertised in a KeyPackage.

kid is a short identifier for the key (a SHA-256 prefix of pub) which envelopes use to say which of the recipient's keys was used. alg is an algorithm id from SecretSharingAlgos; readers skip entries whose alg or use they do not recognise, which is what lets a key package advertise new suites without breaking old readers.
