Consumes the builder, returning an SslConnector.

Methods from Deref<Target = SslContextBuilder>

pub fn as_ptr(&self) -> *mut SSL_CTX

Returns a pointer to the raw OpenSSL value.

pub fn set_verify(&mut self, mode: SslVerifyMode)

Configures the certificate verification method for new connections.

This corresponds to SSL_CTX_set_verify.

pub fn set_verify_callback<F>(&mut self, mode: SslVerifyMode, verify: F)

where F: Fn(bool, &mut X509StoreContextRef) -> bool + 'static + Sync + Send,

Configures the certificate verification method for new connections and registers a verification callback.

The callback is passed a boolean indicating if OpenSSL’s internal verification succeeded as well as a reference to the X509StoreContext which can be used to examine the certificate chain. It should return a boolean indicating if verification succeeded.

This corresponds to SSL_CTX_set_verify.

SNI is used to allow a single server to handle requests for multiple domains, each of which has its own certificate chain and configuration.

Obtain the server name with the servername method and then set the corresponding context with set_ssl_context

This corresponds to SSL_CTX_set_tlsext_servername_callback.

pub fn set_verify_depth(&mut self, depth: u32)

Sets the certificate verification depth.

If the peer’s certificate chain is longer than this value, verification will fail.

This value identifies the server’s session cache to clients, telling them when they’re able to reuse sessions. It should be set to a unique value per server, unless multiple servers share a session cache.

This value should be set when using client certificates, or each request will fail its handshake and need to be restarted.

This corresponds to SSL_CTX_set_session_id_context.

pub fn set_certificate_file<P>( &mut self, file: P, file_type: SslFiletype ) -> Result<(), ErrorStack>

where P: AsRef<Path>,

where F: Fn(&mut SslRef) -> Result<bool, ErrorStack> + 'static + Sync + Send,

Sets the callback dealing with OCSP stapling.

On the client side, this callback is responsible for validating the OCSP status response returned by the server. The status may be retrieved with the SslRef::ocsp_status method. A response of Ok(true) indicates that the OCSP status is valid, and a response of Ok(false) indicates that the OCSP status is invalid and the handshake should be terminated.

On the server side, this callback is responsible for setting the OCSP status response to be returned to clients. The status may be set with the SslRef::set_ocsp_status method. A response of Ok(true) indicates that the OCSP status should be returned to the client, and Ok(false) indicates that the status should not be returned to the client.

This corresponds to SSL_CTX_set_tlsext_status_cb.

pub fn set_psk_client_callback<F>(&mut self, callback: F)

where F: Fn(&mut SslRef, Option<&[u8]>, &mut [u8], &mut [u8]) -> Result<usize, ErrorStack> + 'static + Sync + Send,

Available on non-osslconf="OPENSSL_NO_PSK" only.

pub fn set_psk_server_callback<F>(&mut self, callback: F)

where F: Fn(&mut SslRef, Option<&[u8]>, &mut [u8]) -> Result<usize, ErrorStack> + 'static + Sync + Send,

Available on non-osslconf="OPENSSL_NO_PSK" only.

Sets the callback for providing an identity and pre-shared key for a TLS-PSK server.

This corresponds to SSL_CTX_set_psk_server_callback.

pub fn set_new_session_callback<F>(&mut self, callback: F)

where F: Fn(&mut SslRef, SslSession) + 'static + Sync + Send,

Sets the callback which is called when new sessions are negotiated.

This can be used by clients to implement session caching. While in TLSv1.2 the session is available to access via SslRef::session immediately after the handshake completes, this is not the case for TLSv1.3. There, a session is not generally available immediately, and the server may provide multiple session tokens to the client over a single session. The new session callback is a portable way to deal with both cases.

Note that session caching must be enabled for the callback to be invoked, and it defaults off for clients. set_session_cache_mode controls that behavior.

This corresponds to SSL_CTX_sess_set_new_cb.

pub fn set_remove_session_callback<F>(&mut self, callback: F)

where F: Fn(&SslContextRef, &SslSessionRef) + 'static + Sync + Send,

Sets the callback which is called when sessions are removed from the context.

Sessions can be removed because they have timed out or because they are considered faulty.

This corresponds to SSL_CTX_sess_set_remove_cb.

pub unsafe fn set_get_session_callback<F>(&mut self, callback: F)

where F: Fn(&mut SslRef, &[u8]) -> Option<SslSession> + 'static + Sync + Send,

Sets the callback which is called when a client proposed to resume a session but it was not found in the internal cache.

The callback is passed a reference to the session ID provided by the client. It should return the session corresponding to that ID if available. This is only used for servers, not clients.

Safety

The returned SslSession must not be associated with a different SslContext.

This corresponds to SSL_CTX_sess_set_get_cb.

pub fn set_keylog_callback<F>(&mut self, callback: F)

where F: Fn(&SslRef, &str) + 'static + Sync + Send,

Available on ossl111 only.

where F: Fn(&mut SslRef, &[u8]) -> bool + 'static + Sync + Send,

Available on ossl111 only.

Sets the callback for verifying an application cookie for TLS1.3 stateless handshakes.

The callback will be called with the SSL context and the cookie supplied by the client. It should return true if and only if the cookie is valid.

Note that the OpenSSL implementation independently verifies the integrity of application cookies using an HMAC before invoking the supplied callback.

This corresponds to SSL_CTX_set_stateless_cookie_verify_cb.

pub fn set_cookie_generate_cb<F>(&mut self, callback: F)

where F: Fn(&mut SslRef, &mut [u8]) -> Result<usize, ErrorStack> + 'static + Sync + Send,
