如果多个不同的接受套接字使用相同的OpenSSL上下文是否有问题？

Question

Is it OK if the same OpenSSL context is used by several different accepting sockets?

In particular I'm using the same boost::asio::ssl::context with 2 different listening sockets.

Answer 1

Yep, SSL_CTX--which I believe is the underlying data structure--is just a global data structure used by your program. From ssl(3):

SSL_CTX (SSL Context)

That's the global context structure which is created by a server or client once per program life-time and which holds mainly default values for the SSL structures which are later created for the connections.

Answer 2

It should be OK.

For example a typical RFC4217 FTPS server will use the same SSL context for the control socket and all data sockets within that session.
