TLS Overview

TLS Overview — TLS (aka SSL) support for GSocketConnection

Types and Values

Includes

#include <gio/gio.h>

Description

GTlsConnection and related classes provide TLS (Transport Layer Security, previously known as SSL, Secure Sockets Layer) support for gio-based network streams.

GDtlsConnection and related classes provide DTLS (Datagram TLS) support for GIO-based network sockets, using the GDatagramBased interface. The TLS and DTLS APIs are almost identical, except TLS is stream-based and DTLS is datagram-based. They share certificate and backend infrastructure.

In the simplest case, for a client TLS connection, you can just set the “tls” flag on a GSocketClient, and then any connections created by that client will have TLS negotiated automatically, using appropriate default settings, and rejecting any invalid or self-signed certificates (unless you change that default by setting the “tls-validation-flags” property). The returned object will be a GTcpWrapperConnection, which wraps the underlying GTlsClientConnection.

For greater control, you can create your own GTlsClientConnection, wrapping a GSocketConnection (or an arbitrary GIOStream with pollable input and output streams) and then connect to its signals, such as “accept-certificate”, before starting the handshake.

Server-side TLS is similar, using GTlsServerConnection. At the moment, there is no support for automatically wrapping server-side connections in the way GSocketClient does for client-side connections.

Functions

Types and Values

G_TLS_ERROR

#define G_TLS_ERROR (g_tls_error_quark ())

Error domain for TLS. Errors in this domain will be from the GTlsError enumeration. See GError for more information on error domains.


enum GTlsError

An error code used with G_TLS_ERROR in a GError returned from a TLS-related routine.

Members

G_TLS_ERROR_UNAVAILABLE

No TLS provider is available

 

G_TLS_ERROR_MISC

Miscellaneous TLS error

 

G_TLS_ERROR_BAD_CERTIFICATE

A certificate could not be parsed

 

G_TLS_ERROR_NOT_TLS

The TLS handshake failed because the peer does not seem to be a TLS server.

 

G_TLS_ERROR_HANDSHAKE

The TLS handshake failed because the peer's certificate was not acceptable.

 

G_TLS_ERROR_CERTIFICATE_REQUIRED

The TLS handshake failed because the server requested a client-side certificate, but none was provided. See g_tls_connection_set_certificate().

 

G_TLS_ERROR_EOF

The TLS connection was closed without proper notice, which may indicate an attack. See g_tls_connection_set_require_close_notify().

 

Since: 2.28


enum GTlsAuthenticationMode

The client authentication mode for a GTlsServerConnection.

Members

G_TLS_AUTHENTICATION_NONE

client authentication not required

 

G_TLS_AUTHENTICATION_REQUESTED

client authentication is requested

 

G_TLS_AUTHENTICATION_REQUIRED

client authentication is required

 

Since: 2.28


enum GTlsCertificateFlags

A set of flags describing TLS certification validation. This can be used to set which validation steps to perform (eg, with g_tls_client_connection_set_validation_flags()), or to describe why a particular certificate was rejected (eg, in “accept-certificate”).

Members

G_TLS_CERTIFICATE_UNKNOWN_CA

The signing certificate authority is not known.

 

G_TLS_CERTIFICATE_BAD_IDENTITY

The certificate does not match the expected identity of the site that it was retrieved from.

 

G_TLS_CERTIFICATE_NOT_ACTIVATED

The certificate's activation time is still in the future

 

G_TLS_CERTIFICATE_EXPIRED

The certificate has expired

 

G_TLS_CERTIFICATE_REVOKED

The certificate has been revoked according to the GTlsConnection's certificate revocation list.

 

G_TLS_CERTIFICATE_INSECURE

The certificate's algorithm is considered insecure.

 

G_TLS_CERTIFICATE_GENERIC_ERROR

Some other error occurred validating the certificate

 

G_TLS_CERTIFICATE_VALIDATE_ALL

the combination of all of the above flags

 

Since: 2.28
