Hi,
I signed up with the openssl yesterday and the thread I posted yesterday
with the issue given below is still pending on www.nabble.com. Hence I
decided to just write another email to the above address.
My issue:
I am using openssl to connect to an IIS 6.0 server. I am just getting
alphanumerc (%^$????...etc) characters as the received message for the
first time. Why is this so? Subsequent messages are received correctly
by the IIS server. I have tried my best to research the options I am
setting and have carried out many tests but, no success. I am using the
following flow of commands to negotiate and connect with the IIS server
before posting any data:
SSL_library_init();
SSL_load_error_strings();
httpclient_SSL_CTX = SSL_CTX_new(SSLv3_client_method());
....
....
/* set up SSL structures */
SSL_CTX_sess_set_cache_size(httpclient_SSL_CTX, 20);
SSL_CTX_set_session_cache_mode(httpclient_SSL_CTX,
SSL_SESS_CACHE_CLIENT |
SSL_SESS_CACHE_NO_AUTO_CLEAR);
SSL_CTX_set_timeout(httpclient_SSL_CTX, SESSION_TIMEOUT);
SSL_CTX_set_mode(httpclient_SSL_CTX, 0);
/* set up which ciphers we are willing to use */
/* CIPHER_LIST = "RC4-SHA:RC4-MD5:EXP-RC4-MD5" */
err = SSL_CTX_set_cipher_list(httpclient_SSL_CTX,
CIPHER_LIST);
.....
......
/* create new SSL connection */
hc->SSL_conn = SSL_new(httpclient_SSL_CTX);
..........
/* using SSL for client, not server */
SSL_set_connect_state(hc->SSL_conn);
...........
/* do not enable auto-retry mode for rehandshaking */
SSL_set_mode(hc->SSL_conn, 0);
............
/* connect SSL object to our socket */
SSL_set_fd(hc->SSL_conn, hc->Sock);
/*SESSION_TIMEOUT = 300 seconds */
SSL_set_timeout(hc->SSL_conn->session, SESSION_TIMEOUT);
sslconnect:
ERR_clear_error();
/* negotiate SSL with server */
err = SSL_connect(hc->SSL_conn);
I configured the initial socket as blocking so that SSL_connect only
returns after the complete negotiation. My understanding is that
SSL_connect should take care of all cert and key exchanges so that when
I subsequently use the socket hc->SSL_conn.
Am i missing something here?
Thanks for your help in advance.
