Hi there,
I've just started trying to develop a piece of software with OpenSSL and I
have a rather strange problem I wondered if anyone here might be able to
help explain...
I've initialised OpenSSL like this:
SSL_library_init();
SSL_load_error_strings()
and created a context (error checking omitted for brevity):
m_ssl_ctx = SSL_CTX_new( SSLv23_method() );
SSL_CTX_load_verify_locations( m_ssl_ctx, TRUSTED_CERTS_FILE, NULL );
then created two mem buf BIOs and an SSL object, initialised like this:
m_rbio = BIO_new( BIO_s_mem() );
m_wbio = BIO_new( BIO_s_mem() );
m_ssl = SSL_new( m_ssl_ctx );
SSL_set_bio( m_ssl, m_rbio, m_wbio );
SSL_set_connect_state( m_ssl );
and then I do the following:
ret = SSL_write( m_ssl, buf, buf_lef );
which returns -1, as you'd expect. But (and here's the odd part) when I
call:
SSL_get_error( m_ssl, ret )
it returns SSL_ERROR_WANT_READ, not SSL_ERROR_WANT_WRITE. How can this
be!? The OpenSSL library is setup in client mode, so shouldn't it want to
write a "client hello" to the server first?
Like I said, this is my first attempt at using OpenSSL, so forgive me if
I'm missing something really obvious!
Tim.
