[ietf-dkim] multiple keys under same selector+domain?

2006-04-11 13:43:38
Folks,

I did a quick scan of -core and did not find this issue dealt with:

When moving to a new key for a domain, may the same selector be used, or is the signer required to use a different selector?

Stated differently: Is it true that a given selector+domain DNS lookup name will produce at most one key, forever?

I think some folks believe that it might produce a different key, over time, and I'd like us to be clear about whether it can do that.
