Struct openssl::ssl::Ssl

pub struct Ssl(_);

The state of an SSL/TLS session.

Ssl objects are created from an SslContext, which provides configuration defaults. These defaults can be overridden on a per-Ssl basis, however.

Methods

impl Ssl

pub fn new_ex_index<T>() -> Result<Index<Ssl, T>, ErrorStack> where
    T: 'static + Sync + Send, 

Returns a new extra data index.

Each invocation of this function is guaranteed to return a distinct index. These can be used to store data in the context that can be retrieved later by callbacks, for example.

This corresponds to SSL_get_ex_new_index.

pub fn new(ctx: &SslContext) -> Result<Ssl, ErrorStack>

Creates a new Ssl.

This corresponds to SSL_new.

pub fn connect<S>(self, stream: S) -> Result<SslStream<S>, HandshakeError<S>> where
    S: Read + Write, 

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.

pub fn accept<S>(self, stream: S) -> Result<SslStream<S>, HandshakeError<S>> where
    S: Read + Write, 

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.

Requires OpenSSL 1.0.2 or LibreSSL 2.6.1 or newer.

This corresponds to SSL_get0_alpn_selected.

pub fn set_tlsext_use_srtp(&mut self, protocols: &str) -> Result<(), ErrorStack>

Enables the DTLS extension "use_srtp" as defined in RFC5764.

This corresponds to SSL_set_tlsext_use_srtp.

pub fn srtp_profiles(&self) -> Option<&StackRef<SrtpProtectionProfile>>

Gets all SRTP profiles that are enabled for handshake via set_tlsext_use_srtp

DTLS extension "use_srtp" as defined in RFC5764 has to be enabled.

This corresponds to SSL_get_srtp_profiles.

pub fn selected_srtp_profile(&self) -> Option<&SrtpProtectionProfileRef>

Gets the SRTP profile selected by handshake.

DTLS extension "use_srtp" as defined in RFC5764 has to be enabled.

This corresponds to SSL_get_selected_srtp_profile.

pub fn pending(&self) -> usize

Returns the number of bytes remaining in the currently processed TLS record.

If this is greater than 0, the next call to read will not call down to the underlying stream.

This corresponds to SSL_pending.

pub fn servername(&self, type_: NameType) -> Option<&str>

Returns the servername sent by the client via Server Name Indication (SNI).

It is only useful on the server side.

This corresponds to SSL_get_servername.

Note

While the SNI specification requires that servernames be valid domain names (and therefore ASCII), OpenSSL does not enforce this restriction. If the servername provided by the client is not valid UTF-8, this function will return None. The servername_raw method returns the raw bytes and does not have this restriction.

pub fn servername_raw(&self, type_: NameType) -> Option<&[u8]>

Returns the servername sent by the client via Server Name Indication (SNI).

It is only useful on the server side.

This corresponds to SSL_get_servername.

Note

Unlike servername, this method does not require the name be valid UTF-8.

pub fn set_ssl_context(&mut self, ctx: &SslContextRef) -> Result<(), ErrorStack>

Changes the context corresponding to the current connection.

It is most commonly used in the Server Name Indication (SNI) callback.

This corresponds to SSL_set_SSL_CTX.

pub fn ssl_context(&self) -> &SslContextRef

Returns the context corresponding to the current connection.

This corresponds to SSL_get_SSL_CTX.

pub fn param_mut(&mut self) -> &mut X509VerifyParamRef

Returns a mutable reference to the X509 verification configuration.

Requires OpenSSL 1.0.2 or newer.

This corresponds to SSL_get0_param.

Returns the certificate verification result.

This corresponds to SSL_get_verify_result.

pub fn session(&self) -> Option<&SslSessionRef>

Returns a shared reference to the SSL session.

This corresponds to SSL_get_session.

pub fn export_keying_material(
    &self,
    out: &mut [u8],
    label: &str,
    context: Option<&[u8]>
) -> Result<(), ErrorStack>

Derives keying material for application use in accordance to RFC 5705.

This corresponds to SSL_export_keying_material.

pub unsafe fn set_session(
    &mut self,
    session: &SslSessionRef
) -> Result<(), ErrorStack>

Sets the session to be used.

This should be called before the handshake to attempt to reuse a previously established session. If the server is not willing to reuse the session, a new one will be transparently negotiated.

This corresponds to SSL_set_session.

Safety

The caller of this method is responsible for ensuring that the session is associated with the same SslContext as this Ssl.

pub fn session_reused(&self) -> bool

Determines if the session provided to set_session was successfully reused.

This corresponds to SSL_session_reused.

pub fn set_status_type(&mut self, type_: StatusType) -> Result<(), ErrorStack>

Determines if this Ssl is configured for server-side or client-side use.

This corresponds to SSL_is_server.

pub fn set_ex_data<T>(&mut self, index: Index<Ssl, T>, data: T)

Sets the extra data at the specified index.

This can be used to provide data to callbacks registered with the context. Use the Ssl::new_ex_index method to create an Index.

This corresponds to SSL_set_ex_data.

pub fn ex_data<T>(&self, index: Index<Ssl, T>) -> Option<&T>

Returns a reference to the extra data at the specified index.

This corresponds to SSL_get_ex_data.

pub fn ex_data_mut<T>(&mut self, index: Index<Ssl, T>) -> Option<&mut T>

Returns a mutable reference to the extra data at the specified index.

This corresponds to SSL_get_ex_data.

pub fn finished(&self, buf: &mut [u8]) -> usize

Copies the contents of the last Finished message sent to the peer into the provided buffer.

The total size of the message is returned, so this can be used to determine the size of the buffer required.

This corresponds to SSL_get_finished.

pub fn peer_finished(&self, buf: &mut [u8]) -> usize

Copies the contents of the last Finished message received from the peer into the provided buffer.
