Hi,
Thanks for the clarity of path, but I was also wondering does anybody know
of some simple examples using this as so far the only ones I find using
OpenSSL is when they are introducing their own certificates into the mix it
looks like.
As all I want to do is use what ever the basic certificates as part of the
OS are e.g. in a https transaction. Then send up and back some data.
From API front it looks fairly simple using SSL_read and SSL_write, but I
think for setup I need just say
Sock = <connected socket to port 443>
meth = SSLv23_method()
Cts = SSL_CTX_new(meth);
... (I've removed the code here about setting up your certificate, as I
don't this I think ?)
ssl=SSL_new(cts);
sbio=BIO_new_socket(sock, BIO_NOCLOSE);
SSL_set_bio(ssl,sbio,sbio)
SSL_connect(ssl);
..etc (then any SSL_read / SSL_write's)
And I think that's it, I'm presently building up a sample to prove this but
I wanted to ask if I was heading in the right direction here, or missing
something really obvious.
Yes I need to keep the code as much cross-platform as possible, as would
love to do a MacOS-only code base and use a high level calls, but I need
code to work on Solaris and other platforms as well.
Thanks in advance
Mark.
