RE: non blocking SSL connect

[John Hoel]

The following works on Windows. Haven't tried any other OS. After the TCP connect completes and you have a connected non-blocking socket,   bio = BIO_new_socket( connected_socket, BIO_NOCLOSE ); /* your application closes the socket */ BIO_set_nbio( bio, 1 ); /* tell OpenSSL that the socket is non-blocking */ ssl = SSL_new( ctx ); SSL_set_bio( ssl, bio, bio );   Then repeat the following while connected_socket is active in the writing set and either SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE:   SSL_connect( ssl );   ______________________________ John Hoel Product Author Skywire Software 2401 Internet Blvd., Suite 201 Frisco, Texas 75034 (972)377-1110 main (425)396-4687 direct [EMAIL PROTECTED] www.skywiresoftware.com -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Aftab Alam Sent: Tuesday, May 03, 2005 6:02 AM To: openssl-users@openssl.org Subject: non blocking SSL connect Hi All,   I am trying to create a non blocking ssl connection.   I created a BIO and converted it to non blocking with ioctlsocket on windows and fcntl on linux   if i try http connection on this BIO it works fine and times out at specified time on addresses where it is unable to connect  as non blocking socket should using 'select' but if i convert it into ssl socket, SSL_connect never returns on addresses where it is unable to connect although it works fine with the valid addresses. although the underlying bio is non blocking but SSL_connect still seems to use blocking socket. After converting to nonblocking socket i call SSL_connect this way. pls help me where i am worng   this->m_pSSLSocket = SSL_new(this->m_pSSLContext); SSL_set_bio(this->m_pSSLSocket,Socket,Socket);             int ErrCode = SSL_connect(this->m_pSSLSocket);BIO *socket = BIO_new_connect(host:port);     Regards,   NO RELIANCE:  This e-mail will be of no force of effect and will not be binding unless a hard copy of this e-mail, signed by an authorized official of the company, has been sent to the recipient of this message.
