In addition to= their comments, I will point out that getting the major ESPs to use such = a registry will absolutely never happen. There's no upside for them, and t= he downside (users generating keys, losing them, and receiving unreadable = mail) is very large. So while WKD-style pointers to an authoritative HKP s= erver are very useful for those domains and ESPs that do support them, and= we should have that capability, relying on ESP to register keys as the pr= imary key discovery mechanism for most OpenPGP users is not feasible. -Bart On Wednesday, July 15th, 2026 at 11:58 AM, Andrew Gallagher <andrewg=3D40a= [email protected]> wrote: > Hi, Ashith. > = > You've arrived at an opportune moment, as we are currently working on > this problem area.
