I disagree, it’s more likely a TLS version mismatch.

Nah, it’s probably just a key log issue.

Wait, is SSLv3 still in use? That seems outdated!

I think it's definitely related to the session resumption.

The cipher suite is SSLv3, so that could be an issue.

I think the application data not being decrypted might be due to the session being resumed, but I need to double-check that.

I feel like the key log adjustment could be a factor, but I can't recall the specifics.

I remember something about SSLv3 and TLSv1, but I'm not sure which one is relevant here.

This looks like a straightforward present value calculation, so I think I can handle it. I'll need to use the formula and plug in the given values.

I was leaning toward the hybrid approach since it seems flexible, but I can't recall the specifics of when to apply it effectively.

Wait, doesn't the ServerHello indicate that the session is not resumed? I'm leaning towards option B being the correct answer.

Haha, the 'BigDB Key Log.Tcpdump.Level' made me chuckle. I bet the developers had a hard time coming up with that one.

I'm not sure about the resumed TLS session part, but the cipherSuite indicates it's using RC4, so maybe that's the issue?
