Comment 13 for bug 1461834

Julian, I'm afraid that for better or worse Launchpad did generate 1024-bit RSA keys for PPAs for quite some time, and that wasn't an entirely silly decision back when it was first made - even then DSA had known weaknesses. It's a problem, but as you say we'd need to work out a rollover mechanism. Signing with two keys is certainly a possibility (we did that with the Ubuntu archive for a while, so it's battle-tested), and I expect that any solution to this would involve that, but there's no clear way to end the transition.

Bob, I'm afraid that your proposed "simple" workaround is no such thing (a naive implementation would expose launchpad.net to XSS attacks from user-supplied content on ppa.launchpad.net). I listed the issues that would need to be solved in bug 1473091. Anyway, TLS is a side issue here and this bug shouldn't be derailed into that.

We are very unlikely to do any of the proposed renaming/mirroring hacks; they would be a mess and likely a cure worse than the disease.
