Information request about OpenSSL

[ZSHUser01]

Hi,

I'm writing to ask a couple of question about the openssl library because I'm interestred in understanding how the TLS works. Specifically, I'm interestred to understand better if there's a place in the code where the code for generating the premaster key, master key and session key for the client side is located because I can't seem to find it.

Thank you in advance for the patience and support

This varies a bit by protocol. You're probably mainly interested in the ssl_generate_master_secret, ssl3_generate_master_secret, tls1_generate_master_secret and tls13_generate_master_secret functions

Hi Matt, thank you for providing me the information. I will check this functions that you've mentioned in the source code.

Thank you again for the patience and support
