Simplified SSLv3/TLS from this book Note, $R_{(Alice|Bob)}$ is a random nonce chosen by Alice or Bob respectively, and $\{S\}_{Bob}$ is encryption with Bob's public key. pre-master secret As stated in one of the answer you link to, "The point of a premaster secret is to provide greater consistency between TLS cipher suites." In the figure above, the ...

When a TLS/SSL session starts(after the hellos and cipher decisions) the server gives the client it's cert. The key in the cert could perform different actions depending on the key-agreement algorithm decided on by the client and server. Let's say they agree on RSA key agreement. This means the cert contains the server public RSA key and the server has a ...

If you're just looking for confirmation that the context has logical values being set, then I could say it does. Can't say I know anything about doing this in python though.

The certificate is not encrypted. It contains signatures (basically hashes) that are encrypted with the private key. The public key can decrypt that and the hash can be verified. In SSL/TLS there is a signature that the client supplies via private key to prove they are the owner, and the CA has signed it the cert with their private key, which can be ...
