SSL_set_connect_state, SSL_set_accept_state, SSL_is_server - functions for
manipulating and examining the client or server mode of an SSL object
#include <openssl/ssl.h>
void SSL_set_connect_state(SSL *ssl);
void SSL_set_accept_state(SSL *ssl);
int SSL_is_server(const SSL *ssl);
SSL_set_connect_state() sets
ssl to work in client mode.
SSL_set_accept_state() sets
ssl to work in server mode.
SSL_is_server() checks if
ssl is working in server mode.
When the SSL_CTX object was created with
SSL_CTX_new(3), it was either
assigned a dedicated client method, a dedicated server method, or a generic
method, that can be used for both client and server connections. (The method
might have been changed with
SSL_CTX_set_ssl_version(3) or
SSL_set_ssl_method(3).)
When beginning a new handshake, the SSL engine must know whether it must call
the connect (client) or accept (server) routines. Even though it may be clear
from the method chosen, whether client or server mode was requested, the
handshake routines must be explicitly set.
When using the
SSL_connect(3) or
SSL_accept(3) routines, the
correct handshake routines are automatically set. When performing a
transparent negotiation using
SSL_write_ex(3),
SSL_write(3),
SSL_read_ex(3), or
SSL_read(3), the handshake routines must be
explicitly set in advance using either
SSL_set_connect_state() or
SSL_set_accept_state().
If
SSL_is_server() is called before
SSL_set_connect_state() or
SSL_set_accept_state() is called (either automatically or explicitly),
the result depends on what method was used when SSL_CTX was created with
SSL_CTX_new(3). If a generic method or a dedicated server method was
passed to
SSL_CTX_new(3),
SSL_is_server() returns 1; otherwise,
it returns 0.
SSL_set_connect_state() and
SSL_set_accept_state() do not return
diagnostic information.
SSL_is_server() returns 1 if
ssl is working in server mode or 0
for client mode.
