Missing expires extension

[mbainter]

Is this actually in use by ProtonMail? It has not been updated in any meaningful way in years, and it doesn't have the expire extension present.

Hi @mbainter !

thx for the interest, there hasn't been much activity here indeed. We implemented part of the expire extension some time ago. But, if I remember correctly, we didn't included it in the open source lib because our implementation is incomplete. We may come back to it, finish it and release it but I can't give you any estimate unfortunately as we are working on other things currently.
