I don't know, it seems can't, because the SSL object is created by SSL_new() which dynamic allocated memory for the object,
If you view the file ssl.h, you will found the SSL structure definition, it is complex as it containing many object pointer, so I think it is very hard to manually allocate shared memory to create the SSL object. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dave Peter Sent: Monday, May 09, 2005 3:17 PM To: openssl-users@openssl.org Subject: RE: How to pass SSL connection/object from one process to another?

The Server is already doing this that could pass file descriptor from one process to another, but I wonder when the connection is SSL connection, it should pass both SSL object and the connection file descriptor, so the problem is, how to pass the SSL object to other process? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dave Peter Sent: Monday, May 09, 2005 2:15 PM To: openssl-users@openssl.org Subject: RE: How to pass SSL connection/object from one process to another? You can pass file descriptors from once process to another. Stevens Advance Programming in the Unix Environment chaper 15.3 gives examples of how to do this.

Hi, I wrote a server program that containing 3 executable file. When the main executable file executed, it will execve another 2 executable file and using pipe to communicate with them. Main executable = [Request Parser] Other 2 executable = [Request Handler] Request handling procedure: 1: The [Request Parser] is listening to new connection, when got new client connection, it read the request (text input from client) connection, then parse the text and decide which [Request Handler] process it should send the connection socket and request content to. 2: When the right [Request Handler] received the "request" and connection socket from [Request Parser], then it process the request, 3: Finally, the [Request Handler] output(write) the requesting content(text) to connection socket, then pass the connection socket back to [Request Parser] for keepalive that listen to another request from same client. ################################## Now, I want to implement the OpenSSL to the server that encrypt the communication between the server and client. Due to performance issue, I don't want to use external process like stunnel to encrypt the communication between server and client, I want to add it directly to the server coding that change read() to SSL_read() and write() to SSL_write(). Because upon the handling model, when got new SSL connection from client, the [Request Parser] called SSL_accept() and SSL_read(), then pass connection socket to [Request Handler], I think the [Request Parser] should also pass the SSL connection object to [Request Handler], so the "Request Handler" could call SSL_write to output the content(text) to the client. So, how the [Request Parser] share SSL object/connection with the [Request Handler] or pass the SSL object connection from to [Request Handler]? So the "Request Handler" could correctly using SSL_write and SSL_read to communicate with client. I have been searching the solution on the mailing list in the past few days, but no solution is found. Hope someone could reply me and help to solve the problem. Thanks a lot!
