Particularly for encryption and decryption

For example: https://runkit.com/embed/fe9qrsss9qe4

var jose = require("node-jose");

var keystore = jose.JWK.createKeyStore();
var key = await keystore.generate("oct", 256);
key.alg = "A256GCMKW";

var input = jose.util.randomBytes(32);
await jose.JWE.createEncrypt({ format: 'compact', contentAlg: "A256GCM" }, key).
        update(input).
        final();
