## Detailed Description

TlsClientConnection - TLS client-side connection.

TlsClientConnection is the client-side subclass of TlsConnection, representing a client-side TLS connection.

Since glibmm 2.36:

## Constructor & Destructor Documentation

## ◆ TlsClientConnection() [1/2]

Gio::TlsClientConnection::TlsClientConnection | ( |  | ) |
| protected

You should derive from this class to use it.

## ◆ TlsClientConnection() [2/2]

Gio::TlsClientConnection::TlsClientConnection | ( | TlsClientConnection&& | src | ) |
| noexcept

## ◆ ~TlsClientConnection()

| static

## ◆ copy_session_state()

void Gio::TlsClientConnection::copy_session_state | ( | const Glib::RefPtr< TlsClientConnection >& | source | ) |

Copies session state from one connection to another.

This is not normally needed, but may be used when the same session needs to be used between different endpoints as is required by some protocols such as FTP over TLS. source should have already completed a handshake, and conn should not have completed a handshake.

Since glibmm 2.46:

Parameters

  source | A TlsClientConnection.

## ◆ create() [1/2]

static Glib::RefPtr<TlsClientConnection> Gio::TlsClientConnection::create | ( | const Glib::RefPtr< IOStream >& | base_io_stream | ) |
| static

A create() convenience overload.

static Glib::RefPtr<TlsClientConnection> Gio::TlsClientConnection::create | ( | const Glib::RefPtr< IOStream >& | base_io_stream,
|  | const Glib::RefPtr< const SocketConnectable >& | server_identity
| ) |  |
| static

Creates a new TlsClientConnection wrapping base_io_stream (which must have pollable input and output streams) which is assumed to communicate with the server identified by server_identity.

See the documentation for TlsConnection::property_base_io_stream() for restrictions on when application code can run operations on the base_io_stream after this function has returned.

Since glibmm 2.28:

Parameters

  base_io_stream | The IOStream to wrap.
  server_identity | The expected identity of the server.

Returns
  The new TlsClientConnection, or `nullptr` on error.

Exceptions

Since glibmm 2.28:

Returns
  The list of CA DNs.

## ◆ get_accepted_cas() [2/2]

std::vector< Glib::RefPtr<const Glib::ByteArray> > Gio::TlsClientConnection::get_accepted_cas | ( |  | ) | const

Gets the list of distinguished names of the Certificate Authorities that the server will accept certificates from.

Since glibmm 2.28:

Returns
  A SocketConnectable describing the expected server identity, or `nullptr` if the expected identity is not known.

## ◆ get_server_identity() [2/2]

Glib::RefPtr<const SocketConnectable> Gio::TlsClientConnection::get_server_identity | ( |  | ) | const

Gets conn's expected server identity.

Since glibmm 2.28:

Returns
  A SocketConnectable describing the expected server identity, or `nullptr` if the expected identity is not known.

## ◆ get_type()

static GType Gio::TlsClientConnection::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

## ◆ get_use_ssl3()

bool Gio::TlsClientConnection::get_use_ssl3 | ( |  | ) | const

Gets whether conn will force the lowest-supported TLS protocol version rather than attempt to negotiate the highest mutually- supported version of TLS; see g_tls_client_connection_set_use_ssl3().

Since glibmm 2.28:

Deprecated: 2.56: SSL 3.0 is insecure, and this function does not actually indicate whether it is enabled.

Deprecated:
  SSL 3.0 is insecure, and this function does not actually indicate whether it is enabled.

Returns
  Whether conn will use the lowest-supported TLS protocol version.

## ◆ get_validation_flags()

TlsCertificateFlags Gio::TlsClientConnection::get_validation_flags | ( |  | ) | const

Gets conn's validation flags.

Since glibmm 2.28:

Returns
  The validation flags.

## ◆ gobj() [1/2]

GTlsClientConnection* Gio::TlsClientConnection::gobj | ( |  | ) |

## ◆ property_accepted_cas()

Glib::PropertyProxy_ReadOnly< std::vector< Glib::RefPtr<Glib::ByteArray> > > Gio::TlsClientConnection::property_accepted_cas | ( |  | ) | const

A list of the distinguished names of the Certificate Authorities that the server will accept client certificates signed by.

If the server requests a client certificate during the handshake, then this property will be set after the handshake completes.

Each item in the list is a ByteArray which contains the complete subject DN of the certificate authority.

Since glibmm 2.28:

Deprecated:
  property_accepted_cas() does not work. Use get_accepted_cas() instead.

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_server_identity() [1/2]

Glib::PropertyProxy< Glib::RefPtr<SocketConnectable> > Gio::TlsClientConnection::property_server_identity | ( |  | ) |

A SocketConnectable describing the identity of the server that is expected on the other end of the connection.

If the TLS_CERTIFICATE_BAD_IDENTITY flag is set in TlsClientConnection::property_validation_flags(), this object will be used to determine the expected identify of the remote end of the connection; if TlsClientConnection::property_server_identity() is not set, or does not match the identity presented by the server, then the TLS_CERTIFICATE_BAD_IDENTITY validation will fail.

In addition to its use in verifying the server certificate, this is also used to give a hint to the server about what certificate we expect, which is useful for servers that serve virtual hosts.

Since glibmm 2.28:

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_server_identity() [2/2]

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<SocketConnectable> > Gio::TlsClientConnection::property_server_identity | ( |  | ) | const

A SocketConnectable describing the identity of the server that is expected on the other end of the connection.

If the TLS_CERTIFICATE_BAD_IDENTITY flag is set in TlsClientConnection::property_validation_flags(), this object will be used to determine the expected identify of the remote end of the connection; if TlsClientConnection::property_server_identity() is not set, or does not match the identity presented by the server, then the TLS_CERTIFICATE_BAD_IDENTITY validation will fail.

In addition to its use in verifying the server certificate, this is also used to give a hint to the server about what certificate we expect, which is useful for servers that serve virtual hosts.

Since glibmm 2.28:

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_use_ssl3() [1/2]

Glib::PropertyProxy< bool > Gio::TlsClientConnection::property_use_ssl3 | ( |  | ) |

If `true`, forces the connection to use a fallback version of TLS or SSL, rather than trying to negotiate the best version of TLS to use.

See g_tls_client_connection_set_use_ssl3().

Since glibmm 2.28:

Deprecated: 2.56: SSL 3.0 is insecure, and this property does not generally enable or disable it, despite its name.

Deprecated:

Glib::PropertyProxy< TlsCertificateFlags > Gio::TlsClientConnection::property_validation_flags | ( |  | ) |

What steps to perform when validating a certificate received from a server.

Server certificates that fail to validate in all of the ways indicated here will be rejected unless the application overrides the default via TlsConnection::signal_accept_certificate().

Since glibmm 2.28:

Default value: TLS_CERTIFICATE_UNKNOWN_CA | TLS_CERTIFICATE_BAD_IDENTITY | TLS_CERTIFICATE_NOT_ACTIVATED | TLS_CERTIFICATE_EXPIRED | TLS_CERTIFICATE_REVOKED | TLS_CERTIFICATE_INSECURE | TLS_CERTIFICATE_GENERIC_ERROR

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ set_server_identity()

void Gio::TlsClientConnection::set_server_identity | ( | const Glib::RefPtr< SocketConnectable >& | identity | ) |

Sets conn's expected server identity, which is used both to tell servers on virtual hosts which certificate to present, and also to let conn know what name to look for in the certificate when performing TLS_CERTIFICATE_BAD_IDENTITY validation, if enabled.

Since glibmm 2.28:

Parameters

  identity | A SocketConnectable describing the expected server identity.

## ◆ set_use_ssl3()

void Gio::TlsClientConnection::set_use_ssl3 | ( | bool | use_ssl3 = `true` | ) |

Since 2.42.1, if use_ssl3 is `true`, this forces conn to use the lowest-supported TLS protocol version rather than trying to properly negotiate the highest mutually-supported protocol version with the peer.

Be aware that SSL 3.0 is generally disabled by the TlsBackend, so the lowest-supported protocol version is probably not SSL 3.0.

Since 2.58, this may additionally cause an RFC 7507 fallback SCSV to be sent to the server, causing modern TLS servers to immediately terminate the connection. You should generally only use this function if you need to connect to broken servers that exhibit TLS protocol version intolerance, and when an initial attempt to connect to a server normally has already failed.

Since glibmm 2.28:

Deprecated: 2.56: SSL 3.0 is insecure, and this function does not generally enable or disable it, despite its name.

Deprecated:
  SSL 3.0 is insecure, and this function does not generally enable or disable it, despite its name.

Parameters

  use_ssl3 | Whether to use the lowest-supported protocol version.

## ◆ set_validation_flags()

void Gio::TlsClientConnection::set_validation_flags | ( | TlsCertificateFlags | flags | ) |

Sets conn's validation flags, to override the default set of checks performed when validating a server certificate.

By default, TLS_CERTIFICATE_VALIDATE_ALL is used.

Since glibmm 2.28:

Parameters

  flags | The TlsCertificateFlags to use.
