Memory-managed wrapper type.

Type class for types which can be safely cast to TlsClientConnection, for instance with toTlsClientConnection.

Cast to TlsClientConnection, for types for which this is known to be safe. For general casts, use castTo.

Possibly copies session state from one connection to another, for use in TLS session resumption. 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, since TLS 1.3, it should have been used to read data at least once. conn should not have completed a handshake.

It is not possible to know whether a call to this function will actually do anything. Because session resumption is normally used only for performance benefit, the TLS backend might not implement this function. Even if implemented, it may not actually succeed in allowing conn to resume source's TLS session, because the server may not have sent a session resumption token to source, or it may refuse to accept the token from conn. There is no way to know whether a call to this function is actually successful.

Using this function is not required to benefit from session resumption. If the TLS backend supports session resumption, the session will be resumed automatically if it is possible to do so without weakening the privacy guarantees normally provided by TLS, without need to call this function. For example, with TLS 1.3, a session ticket will be automatically copied from any TlsClientConnection that has previously received session tickets from the server, provided a ticket is available that has not previously been used for session resumption, since session ticket reuse would be a privacy weakness. Using this function causes the ticket to be copied without regard for privacy considerations.

Since: 2.46

Gets the list of distinguished names of the Certificate Authorities that the server will accept certificates from. This will be set during the TLS handshake if the server requests a certificate. Otherwise, it will be Nothing.

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

Since: 2.28

Gets conn's expected server identity

Since: 2.28

SSL 3.0 is no longer supported. See tlsClientConnectionSetUseSsl3 for details.

Since: 2.28

Gets conn's validation flags

This function does not work as originally designed and is impossible to use correctly. See TlsClientConnection:validationFlags for more information.

Since: 2.28

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

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

Since: 2.28

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 TlsCertificateFlagsBadIdentity validation, if enabled.

Since: 2.28

Since GLib 2.42.1, SSL 3.0 is no longer supported.

From GLib 2.42.1 through GLib 2.62, this function could be used to force use of TLS 1.0, the lowest-supported TLS protocol version at the time. In the past, this was needed to connect to broken TLS servers that exhibited protocol version intolerance. Such servers are no longer common, and using TLS 1.0 is no longer considered acceptable.

Since GLib 2.64, this function does nothing.

Since: 2.28

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

This function does not work as originally designed and is impossible to use correctly. See TlsClientConnection:validationFlags for more information.

Since: 2.28

Get the value of the “accepted-cas” property. When overloading is enabled, this is equivalent to

get tlsClientConnection #acceptedCas

Construct a GValueConstruct with valid value for the “server-identity” property. This is rarely needed directly, but it is used by new.

Get the value of the “server-identity” property. When overloading is enabled, this is equivalent to

get tlsClientConnection #serverIdentity

Set the value of the “server-identity” property. When overloading is enabled, this is equivalent to

set tlsClientConnection [ #serverIdentity := value ]

Construct a GValueConstruct with valid value for the “use-ssl3” property. This is rarely needed directly, but it is used by new.

Get the value of the “use-ssl3” property. When overloading is enabled, this is equivalent to

get tlsClientConnection #useSsl3

Set the value of the “use-ssl3” property. When overloading is enabled, this is equivalent to

set tlsClientConnection [ #useSsl3 := value ]

Construct a GValueConstruct with valid value for the “validation-flags” property. This is rarely needed directly, but it is used by new.

Get the value of the “validation-flags” property. When overloading is enabled, this is equivalent to

get tlsClientConnection #validationFlags

Set the value of the “validation-flags” property. When overloading is enabled, this is equivalent to

set tlsClientConnection [ #validationFlags := value ]
