openssl_capture.txt
<http://openssl.6102.n7.nabble.com/file/n48871/openssl_capture.txt> Hello,
I'm using OpenSSL in order to encrypt some emails, that a piece of hardware
sends. But, whenever I try to call SSL_connect(), I get : SSL
routines:SSL23_GET_SERVER_HELLO:unknown protocol
After sending "EHLO" and "STARTTLS" I call the following function:
///////////////////////////////////////////////////////////////////////////////////////////////
SSL_CTX *ctx = NULL;
SSL *ssl = NULL;
void CreateTLSSession(int sockfd)
{
printf("///////////////creating TLS
Session/////////////////////\n");
SSL_library_init();
SSL_load_error_strings();
OpenSSL_add_all_algorithms();
ctx = SSL_CTX_new(SSLv23_client_method());
if (ctx == NULL)
{
printf("failed to initialize context\n");
return;
}
SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2);
ssl = SSL_new(ctx);
if (!SSL_set_fd(ssl, sockfd))
{
printf("failed to bind to socket fd\n");
return;
}
if (SSL_connect(ssl) < 1)
{
ERR_print_errors_fp(stdout);
fflush(stdout);
printf("SSL_connect failed\n");
return;
}
}
////////////////////////////////////////////////////////////////////////////////////////////////////
I've tried connecting to :
smtp.live.com : 587 --> SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
s23_clnt.c:787:
smtp.live.com : 25 --> SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
s23_clnt.c:787:
smtp.gmail.com : 587 --> SSL routines:SSL23_GET_SERVER_HELLO:unknown
protocol s23_clnt.c:787:
smtp.gmail.com : 465 --> no response from server at all!
smtp.gmail.com : 25 --> SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol
s23_clnt.c:787:
Am I missing something here?
UPDATE:
All other methods (i.e. TLSv1_1_method(), SSLv3_method() ...) lead to
SSL3_GET_RECORD:wrong version number
UPDATE: I've managed to sniff the network traffic using wireshark. The .txt
capture file is attached.
Any help will be appreciated
