I'm current deverlop a server which use asyn socket (use IOCP), and now i want to add OpenSSL authentication in my socket. But in my socket, methold WSASend() don't like methold SSL_write which I used.
Do you have any idea for me?
Thanks in advance!!
One typical use of BIO pairs is to place TLS/SSL I/O under application control, this can be used when the application wishes to use a non standard transport for TLS/SSL or the normal socket routines are inappropriate.

I wrote an article for Windows Developer Magazine back in 2002 which showed how to use OpenSSL BIO pairs to write an SSL adapter for an MFC async socket. The article and code are here: http://www.lenholgate.com/archives/000456.html. This should show you what you need to do to use overlapped IOCP sockets with OpenSSL - in fact this was the test project which I developed whilst working on the ideas that eventually went into our licensed IOCP framework's OpenSSL support (see here (http://www.lenholgate.com/ServerFram...licensing.html), if you're interested in the framework)
That's true, either way, it works and the example provides a compilable and working solution to the problem which is equally applicable to the IOCP situation.
I seem to remember that there was an issue with using a BIO pair at the time; but looking at the man page now it seems that perhaps it was simply that I didn't understand that you needed to free the network bio yourself but that the internal bio was freed for you... It was a long time ago...
