Another option could be a post boot task. So it's still eager but don't block completed start. We'd still need to block Tls ports though. So maybe this does not help

2048 bits adds close to a second to first boot on my machine (obviously subsequent boots are unaffected).

This is probably a bit much, I will work on getting a POC for the lazy loading approach implemented.

We should really be generating 2048 bit keys. 

I don't like adding to our boot time, we have already seen it grow and this would be yet another case.

So I just did up a very quick prototype that generates self signed certificates on startup and it looks like the difference in startup time is negligible (at least when generating 1024 bit RSA keys). Even if the difference is measurable it only affects the very first startup.

I think that in order to simplify the implementation of this it may be better to simply generate the key of first startup, instead of attempting to do it lazily.

What will be default keysize? It has to be probably choosen to work also without "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy"

Probably the largest that is supported without JCE. It does not matter that much, self signed certs are inherently insecure, this is a developer usability feature, not something that can be used in production.

IIRC there is actually no limit on RSA key size, it's only symmetric algs that are limited, so we could use a standard 2048 bit key without issue.

So I guess we should talk about how this should actually work.

In terms of auto generating the key I was thinking we would need to add a new attribute to the 'keystore' element under the security realm, something like 'auto-generate-cert-host="localhost"'. I am not sure what other options we would need, or how configurable we should make it, but as this is for testing/development purposes I don't think we need to expose full control over the certificate generation process.

In terms of the implementation we could just implement an SSLContext wrapper, that can do the generation and then create a 'real' SSLContext the first time it is asked to create and SSLEngine.

Hi Harold,

That fix is already in master, so it will be included in 10.1.
