Canonical JSON would [probably] be cool but it isn't a reality.
Anyway, I have continued the quest into ES6 and the canonicalization of Numbers
and AFAICT [1] a bunch of ES6-vendors [2] have selected algorithms [3] that
produce
deterministic and interoperable values for serializing and deserializing
Numbers.
That is, no workarounds of any kind are necessary for using in-object JS or
JSON signatures
like the JS-example below which was created by my just updated reference
implementation:
var reading =
{
device: "Pump2",
value: 13000,
signature:
{
algorithm: "ES256",
publicKey:
{
type: "EC",
curve: "P-256",
x: "ajlL4ksVEi-T589G7X9H4VOLoqbMkzPQw_GQFvUIXMA",
y: "BdNg_sfSs6cZsYiMoRSmvnFOHXHJhYf9adQTkP1yweA"
},
value:
"VMbKgogiOeoWQd7tT9_vqNVxUm0fg7phsITvfj6Ggd_ghYj0BzW30QOS69tiYL0tTIEMVI4Kf9ZnQUocrr7XYQ"
}
};
