I’m grateful to be able to do reseach as part of my job. I would love to be proven wrong, though.Īs previously, this work is part of my R&D activities at SolidLab LLC and was fully funded by the company.

My experiments show that for TLS1.3 session resumption is not currently supported by Schannel.

The tool for exporting the keys was update with this new extraction method.

Researching resumption helped identify an easier target for hooking the works both for resumed and non-resumed TLS1.2 sessions and does not have problems with session hashing, namely SslGenerateSessionKeys.

Methods and results from Jacob Cambic’s research still largely apply, but some of the offsets have since changed.Resumption for TLS1.2 is only performed when extended master secret extension is in use.For TLS1.2 schannel does session resumption both with session IDs and tickets.I’ve also redone some of the experiments from Jacob Cambic’s research to discover if something has changed from the time it was written. This part is about dealing with session resumption. I recommend at least skimming through part 1 before reading this one, because it contains a lot of important context that is omitted in part 2.

How can I decrypt TLS messages when an ephemeral Diffie-Hellman ciphersuite is used? I am able to expose the premaster secret and master secret from the SSL Client.
