In our next Open Port, Josh Aas, co-founder of Internet Security Research Group (ISRG) will join us from the US. We will have the chance to discuss the trade-offs associated with various cryptographic certificate lifetimes, which include the impact on revocation and reliability.

Josh will also provide us with a preview of the plans of Let's Encrypt on certificate lifetimes, as well as some thoughts on what post-quantum support could mean.
