ssl::stream

Provides stream-oriented functionality using SSL.

template<
    typename Stream>
class stream :
  public ssl::stream_base,
  noncopyable

Types

Name	Description
impl_struct	Structure for use with deprecated impl_type.
executor_type	The type of the executor associated with the object.
handshake_type	Different handshake types.
lowest_layer_type	The type of the lowest layer.
native_handle_type	The native handle type of the SSL stream.
next_layer_type	The type of the next layer.

Member Functions

Name	Description
async_handshake	Start an asynchronous SSL handshake.
async_read_some	Start an asynchronous read.
async_shutdown	Asynchronously shut down SSL on the stream.
async_write_some	Start an asynchronous write.
get_executor	Get the executor associated with the object.
get_io_context	(Deprecated: Use get_executor().) Get the io_context associated with the object.
get_io_service	(Deprecated: Use get_executor().) Get the io_context associated with the object.
handshake	Perform SSL handshaking.
lowest_layer	Get a reference to the lowest layer.
native_handle	Get the underlying implementation in the native type.
next_layer	Get a reference to the next layer.
read_some	Read some data from the stream.
set_verify_callback	Set the callback used to verify peer certificates.
set_verify_depth	Set the peer verification depth.
set_verify_mode	Set the peer verification mode.
shutdown	Shut down SSL on the stream.
stream	Construct a stream.
write_some	Write some data to the stream.
~stream	Destructor.

The stream class template provides asynchronous and blocking stream-oriented functionality using SSL.

Thread Safety

Distinct objects: Safe.

Shared objects: Unsafe. The application must also ensure that all asynchronous operations are performed within the same implicit or explicit strand.

Example

To use the SSL stream template with an ip::tcp::socket, you would write:

asio::io_context io_context;
asio::ssl::context ctx(asio::ssl::context::sslv23);
asio::ssl::stream<asio:ip::tcp::socket> sock(io_context, ctx);
