OpenSSL compilation errors in Windows

[Nagalakshmi V J]

Hi Matt,

Thank you so much for your response. Those mentioned APIs resolved my errors.

For the below code,

 return  SSL_get_session(pConnection) != NULL &&
                pConnection->session->session_id_length != 0;

Any reference for accessing session_id_length?
https://www.openssl.org/docs/man1.1.0/man3/SSL_CTX_set_generate_session_id.html

Not sure if I can use the above link.


Thanks & Regards,
Nagalakshmi V J

It seems your code is replicating parts of libssl - which seems like a
strange (and possibly dangerous) thing to do!

You really don't need to access these things. They're just cached
references to the value returned by EVP_get_digestbyname("ssl3-md5") and
EVP_get_digestbyname("ssl3-sha1"). So you can call those functions
directly anyway.
