GTlsBackend

GTlsBackend — TLS backend implementation

Object Hierarchy

    GInterface
    ╰── GTlsBackend

Prerequisites

GTlsBackend requires GObject.

Includes

#include <gio/gio.h>

Description

TLS (Transport Layer Security, aka SSL) and DTLS backend.

Functions

g_tls_backend_get_default ()

GTlsBackend *
g_tls_backend_get_default (void);

Gets the default GTlsBackend for the system.

Returns

a GTlsBackend.

[transfer none]

Since: 2.28


g_tls_backend_supports_tls ()

gboolean
g_tls_backend_supports_tls (GTlsBackend *backend);

Checks if TLS is supported; if this returns FALSE for the default GTlsBackend, it means no "real" TLS backend is available.

Parameters

backend

the GTlsBackend

 

Returns

whether or not TLS is supported

Since: 2.28


g_tls_backend_supports_dtls ()

gboolean
g_tls_backend_supports_dtls (GTlsBackend *backend);

Checks if DTLS is supported. DTLS support may not be available even if TLS support is available, and vice-versa.

Parameters

backend

the GTlsBackend

 

Returns

whether DTLS is supported

Since: 2.48


g_tls_backend_get_default_database ()

GTlsDatabase *
g_tls_backend_get_default_database (GTlsBackend *backend);

Gets the default GTlsDatabase used to verify TLS connections.

Parameters

backend

the GTlsBackend

 

Returns

the default database, which should be unreffed when done.

[transfer full]

Since: 2.30


g_tls_backend_get_certificate_type ()

GType
g_tls_backend_get_certificate_type (GTlsBackend *backend);

Gets the GType of backend 's GTlsCertificate implementation.

Parameters

backend

the GTlsBackend

 

Returns

the GType of backend 's GTlsCertificate implementation.

Since: 2.28


g_tls_backend_get_client_connection_type ()

GType
g_tls_backend_get_client_connection_type
                               (GTlsBackend *backend);

Gets the GType of backend 's GTlsClientConnection implementation.

Parameters

backend

the GTlsBackend

 

Returns

the GType of backend 's GTlsClientConnection implementation.

Since: 2.28


g_tls_backend_get_server_connection_type ()

GType
g_tls_backend_get_server_connection_type
                               (GTlsBackend *backend);

Gets the GType of backend 's GTlsServerConnection implementation.

Parameters

the GTlsBackend

 

Returns

the GType of backend 's GTlsServerConnection implementation.

Since: 2.28


g_tls_backend_get_dtls_client_connection_type ()

GType
g_tls_backend_get_dtls_client_connection_type
                               (GTlsBackend *backend);

Gets the GType of backend ’s GDtlsClientConnection implementation.

Parameters

the GTlsBackend

 

Returns

the GType of backend ’s GDtlsClientConnection implementation.

Since: 2.48


g_tls_backend_get_dtls_server_connection_type ()

GType
g_tls_backend_get_dtls_server_connection_type
                               (GTlsBackend *backend);

Gets the GType of backend ’s GDtlsServerConnection implementation.

Parameters

backend

the GTlsBackend

 

Returns

the GType of backend ’s GDtlsServerConnection implementation.

Since: 2.48


g_tls_backend_get_file_database_type ()

GType
g_tls_backend_get_file_database_type (GTlsBackend *backend);

Gets the GType of backend 's GTlsFileDatabase implementation.

Parameters

backend

the GTlsBackend

 

Returns

the GType of backend's GTlsFileDatabase implementation.

Since: 2.30

G_TLS_BACKEND_EXTENSION_POINT_NAME

#define G_TLS_BACKEND_EXTENSION_POINT_NAME "gio-tls-backend"

Extension point for TLS functionality via GTlsBackend. See Extending GIO.


GTlsBackend

typedef struct _GTlsBackend GTlsBackend;

TLS (Transport Layer Security, aka SSL) and DTLS backend. This is an internal type used to coordinate the different classes implemented by a TLS backend.

Since: 2.28


struct GTlsBackendInterface

struct GTlsBackendInterface {
  GTypeInterface g_iface;

  /* methods */
  gboolean       ( *supports_tls)               (GTlsBackend *backend);
  GType          ( *get_certificate_type)       (void);
  GType          ( *get_client_connection_type) (void);
  GType          ( *get_server_connection_type) (void);
  GType          ( *get_file_database_type)     (void);
  GTlsDatabase * ( *get_default_database)       (GTlsBackend *backend);
  gboolean       ( *supports_dtls)              (GTlsBackend *backend);
  GType          ( *get_dtls_client_connection_type) (void);
