That’s not how keygen works. The keygen tag has to be part of a form, and renders a visible indication of the key size. The end user has to actively click on something before the key is generated.

Sorry, but that’s untrue. At the very least (Firefox) you have to explicit submit a form to generate a key. At the most (Safari) you are explicitly prompted to choose a certificate before using that certificate to connect to a site.

In that case I expect you’ll be withdrawing your proposal and will be leaving keygen as it is?
