Kyle, I'm merely an observer of EDIINT's activities, but this caught my eye. I think that if you expect ASx to have a life far beyond its publication date, it should not be so firmly tied to whatever algorithms are currently in vogue. Partners and communities have different requirements, and those requirements may change over time; they can and do specify them in the form of deployment profiles and trading partner agreements. The nice thing about SSL/TLS negotiation is that lack of a common ciphersuite leads to a precise and predictable failure state that can easily be reported by one's application in explicit detail; there should be no mystery about why the client and server don't interoperate, and what one must do to fix the problem. --Pete Thus spoke Kyle Meadors ([email protected]) on Tue, Jun 21, 2005 at 01:58:56PM -0500: > An issue was recently brought up in regards to using TLS in AS3.
