Regarding Section 11.2:

id

For all Keys visible within a given origin, each Key shall have a unique, opaque identifier assigned that may be used to uniquely identify that Key within the set of keys.

Within the same origin, if two Keys are created from the same underlying keying material, they MUST share the same id.

What is meant by "if two Keys are created from the same underlying keying material" here?

Does this mean that if I have some key material that I use as an AES key in one case and as a 3DES key in another, they will have the same ID?

Also, would the algorithm be such that if my keying material on one device matched the keying material on another device that this ID would be identical for the same origin?
