I have a running program, the program is written in C
I want to convert it from connecting to an HTTP to HTTPS (SSL)
I have an event for write/read/timeout/error and such
How do I continue and use the current sockets FD I have, but using openSSL
over it? the most easy and simple way?
I have created a CTX object, and an SSL object over it (SSL_new(..))
I thought about using BIO_new_socket, but having problems with the
connection/ hand shake and reading/writing data (I am the client code only)
Try BIO_new_socket + BIO_set_fd
Then do the standard OpenSSL socket loop that repeatedly checks if
OpenSSL wants you to wait for socket send ready, socket receive
ready, data from application ready or data to application ready,
then proceeds accordingly (There is an example in apps/s_client.c,
but it is difficult to read and contains optional stuff you won't
need in your app). I think there is a better example somewhere.
Enjoy
