Supper.
I understand it now.
Thanks for the details !
I can really understand why people both LOVE and HATE this langauge.
SO much fuctionality is packed into so few charecters - makes the code terse and fuctional, but hard to understand unless yon know the 'secret code"

ssl_ctx_new
SSL_CTX_new(3) OpenSSL SSL_CTX_new(3)
NAME
SSL_CTX_new - create a new SSL_CTX object as framework for TLS/SSL enabled functions
SYNOPSIS
#include <openssl/ssl.h>
SSL_CTX *SSL_CTX_new(const SSL_METHOD *method);
DESCRIPTION
SSL_CTX_new() creates a new SSL_CTX object as framework to establish TLS/SSL enabled connections.
NOTES
The SSL_CTX object uses method as connection method. The methods exist in a generic type (for client and server use), a server only type,
and a client only type. method can be of the following types:
SSLv2_method(void), SSLv2_server_method(void), SSLv2_client_method(void)
A TLS/SSL connection established with these methods will only understand the SSLv2 protocol. A client will send out SSLv2 client hello
messages and will also indicate that it only understand SSLv2. A server will only understand SSLv2 client hello messages.
SSLv3_method(void), SSLv3_server_method(void), SSLv3_client_method(void)
A TLS/SSL connection established with these methods will only understand the SSLv3 protocol. A client will send out SSLv3 client hello
messages and will indicate that it only understands SSLv3. A server will only understand SSLv3 client hello messages. This especially
means, that it will not understand SSLv2 client hello messages which are widely used for compatibility reasons, see SSLv23_*_method().
TLSv1_method(void), TLSv1_server_method(void), TLSv1_client_method(void)
A TLS/SSL connection established with these methods will only understand the TLSv1 protocol. A client will send out TLSv1 client hello
messages and will indicate that it only understands TLSv1. A server will only understand TLSv1 client hello messages. This especially
means, that it will not understand SSLv2 client hello messages which are widely used for compatibility reasons, see SSLv23_*_method().
It will also not understand SSLv3 client hello messages.
SSLv23_method(void), SSLv23_server_method(void), SSLv23_client_method(void)
A TLS/SSL connection established with these methods will understand the SSLv2, SSLv3, and TLSv1 protocol. A client will send out SSLv2
client hello messages and will indicate that it also understands SSLv3 and TLSv1. A server will understand SSLv2, SSLv3, and TLSv1
client hello messages. This is the best choice when compatibility is a concern.
The list of protocols available can later be limited using the SSL_OP_NO_SSLv2, SSL_OP_NO_SSLv3, SSL_OP_NO_TLSv1 options of the
SSL_CTX_set_options() or SSL_set_options() functions. Using these options it is possible to choose e.g. SSLv23_server_method() and be able
to negotiate with all possible clients, but to only allow newer protocols like SSLv3 or TLSv1.
SSL_CTX_new() initializes the list of ciphers, the session cache setting, the callbacks, the keys and certificates, and the options to its
default values.
RETURN VALUES
The following return values can occur:
NULL
The creation of a new SSL_CTX object failed. Check the error stack to find out the reason.
Pointer to an SSL_CTX object
The return value points to an allocated SSL_CTX object.
