boost asio ssl async_write send me mostly gibberish

I'm in the process of converting my non secure socket to ssl, using boost::asio::ssl

While everything was working fine with non-ssl, async_write send me mostly gibberish.

The funny thing is when I put a sleep(1) between every async_write, I get mostly good data, with a little gibberish (something like that "?????@??" )

The faster I send data the most gibberish it gets... I'm completely lost on this problem !

initSSLConnection :

boost::asio::ssl::context *m_context = new boost::asio::ssl::context(m_acceptor.io_service(), boost::asio::ssl::context::sslv23);
 m_context->set_options(boost::asio::ssl::context::default_workarounds
                       | boost::asio::ssl::context::no_sslv2
                       | boost::asio::ssl::context::single_dh_use);
 m_context->set_password_callback(boost::bind(&Server::get_password, this));
 m_context->use_certificate_chain_file("./ssl_key/cert.pem");
 m_context->use_private_key_file("./ssl_key/key.pem", boost::asio::ssl::context::pem);

write on Socket :

while (1) {
boost::asio::async_write(m_socket,                                              
                          boost::asio::buffer(ss.str().c_str(), ss.str().size()),
                          boost::bind(&MyClass::done_writing,                        
             开发者_如何学编程                         shared_from_this())
                          );
}

Here's what I get when I do not put sleep(1) :

It seems that it is encoded or something...

I connect to the server via this command line :

openssl s_client -ssl3 -connect 127.0.0.1:4242 

The problem is that you are interleaving writes..

while (1) {
boost::asio::async_write(m_socket,                                              
                          boost::asio::buffer(ss.str().c_str(), ss.str().size()),
                          boost::bind(&MyClass::done_writing,                        
                                      shared_from_this())
                          );
}

You should only do the next async_write, once the first one completes - i.e. in the done_writing handler. This is why you get crap as you make more calls...
