Expand description

A TLS session over a stream.

Fields

ssl: ManuallyDrop<Ssl>method: ManuallyDrop<BioMethod>_p: PhantomData<S>

Implementations

Creates a new SslStream.

This function performs no IO; the stream will not have performed any part of the handshake with the peer. If the Ssl was configured with SslRef::set_connect_state or SslRef::set_accept_state, the handshake can be performed automatically during the first call to read or write. Otherwise the connect and accept methods can be used to explicitly perform the handshake.

This corresponds to SSL_set_bio.

👎 Deprecated since 0.10.32:

use Ssl::from_ptr and SslStream::new instead

Constructs an SslStream from a pointer to the underlying OpenSSL SSL struct.

This is useful if the handshake has already been completed elsewhere.

Safety

The caller must ensure the pointer is valid.

Read application data transmitted by a client before handshake completion.

Useful for reducing latency, but vulnerable to replay attacks. Call SslRef::set_accept_state first.

Returns Ok(0) if all early data has been read.

Requires OpenSSL 1.1.1 or newer.

This corresponds to SSL_read_early_data.

Send data to the server without blocking on handshake completion.

Useful for reducing latency, but vulnerable to replay attacks. Call SslRef::set_connect_state first.

Requires OpenSSL 1.1.1 or newer.

This corresponds to SSL_write_early_data.

Initiates a client-side TLS handshake.

This corresponds to SSL_connect.

Warning

OpenSSL’s default configuration is insecure. It is highly recommended to use SslConnector rather than Ssl directly, as it manages that configuration.

Initiates a server-side TLS handshake.

This corresponds to SSL_accept.

Warning

OpenSSL’s default configuration is insecure. It is highly recommended to use SslAcceptor rather than Ssl directly, as it manages that configuration.

Initiates the handshake.

This will fail if set_accept_state or set_connect_state was not called first.

This corresponds to SSL_do_handshake.

Perform a stateless server-side handshake.

Requires that cookie generation and verification callbacks were set on the SSL context.

Returns Ok(true) if a complete ClientHello containing a valid cookie was read, in which case the handshake should be continued via accept. If a HelloRetryRequest containing a fresh cookie was transmitted, Ok(false) is returned instead. If the handshake cannot proceed at all, Err is returned.

This corresponds to SSL_stateless

Like read, but returns an ssl::Error rather than an io::Error.

It is particularly useful with a nonblocking socket, where the error value will identify if OpenSSL is waiting on read or write readiness.

This corresponds to SSL_read.

Like write, but returns an ssl::Error rather than an io::Error.

It is particularly useful with a nonblocking socket, where the error value will identify if OpenSSL is waiting on read or write readiness.

This corresponds to SSL_write.

Reads data from the stream, without removing it from the queue.

This corresponds to SSL_peek.

Shuts down the session.

The shutdown process consists of two steps. The first step sends a close notify message to the peer, after which ShutdownResult::Sent is returned. The second step awaits the receipt of a close notify message from the peer, after which ShutdownResult::Received is returned.

While the connection may be closed after the first step, it is recommended to fully shut the session down. In particular, it must be fully shut down if the connection is to be used for further communication in the future.

This corresponds to SSL_shutdown.

Returns the session’s shutdown state.

This corresponds to SSL_get_shutdown.

Sets the session’s shutdown state.

This can be used to tell OpenSSL that the session should be cached even if a full two-way shutdown was not completed.

This corresponds to SSL_set_shutdown.

Returns a shared reference to the underlying stream.

Returns a mutable reference to the underlying stream.

Warning

It is inadvisable to read from or write to the underlying stream as it will most likely corrupt the SSL session.

Returns a shared reference to the Ssl object associated with this stream.
