Struct DtlsClientConnection

pub struct DtlsClientConnection { /* private fields */ }

GDtlsClientConnection is the client-side subclass of DtlsConnection, representing a client-side DTLS connection.

Properties

accepted-cas

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 #GByteArray which contains the complete subject DN of the certificate authority.

Readable

server-identity

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

If the TlsCertificateFlags::BAD_IDENTITY flag is set in #GDtlsClientConnection:validation-flags, this object will be used to determine the expected identify of the remote end of the connection; if #GDtlsClientConnection:server-identity is not set, or does not match the identity presented by the server, then the TlsCertificateFlags::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.

validation-flags

What steps to perform when validating a certificate received from a server. Server certificates that fail to validate in any of the ways indicated here will be rejected unless the application overrides the default via #GDtlsConnection::accept-certificate.

GLib guarantees that if certificate verification fails, at least one flag will be set, but it does not guarantee that all possible flags will be set. Accordingly, you may not safely decide to ignore any particular type of error. For example, it would be incorrect to mask TlsCertificateFlags::EXPIRED if you want to allow expired certificates, because this could potentially be the only error flag set even if other problems exist with the certificate. Therefore, there is no safe way to use this property. This is not a horrible problem, though, because you should not be attempting to ignore validation errors anyway. If you really must ignore TLS certificate errors, connect to #GDtlsConnection::accept-certificate.

DtlsConnection

advertised-protocols

The list of application-layer protocols that the connection advertises that it is willing to speak. See g_dtls_connection_set_advertised_protocols().

Readable | Writeable

base-socket

The #GDatagramBased that the connection wraps. Note that this may be any implementation of #GDatagramBased, not just a #GSocket.

Readable | Writeable | Construct Only

certificate

The connection’s certificate; see g_dtls_connection_set_certificate().

Readable | Writeable

ciphersuite-name

The name of the DTLS ciphersuite in use. See g_dtls_connection_get_ciphersuite_name().

Readable

database

The certificate database to use when verifying this TLS connection. If no certificate database is set, then the default database will be used. See g_tls_backend_get_default_database().

When using a non-default database, #GDtlsConnection must fall back to using the #GTlsDatabase to perform certificate verification using g_tls_database_verify_chain(), which means certificate verification will not be able to make use of TLS session context. This may be less secure. For example, if you create your own #GTlsDatabase that just wraps the default #GTlsDatabase, you might expect that you have not changed anything, but this is not true because you may have altered the behavior of #GDtlsConnection by causing it to use g_tls_database_verify_chain(). See the documentation of g_tls_database_verify_chain() for more details on specific security checks that may not be performed. Accordingly, setting a non-default database is discouraged except for specialty applications with unusual security requirements.

Readable | Writeable

interaction

A #GTlsInteraction object to be used when the connection or certificate database need to interact with the user. This will be used to prompt the user for passwords where necessary.

Readable | Writeable

negotiated-protocol

The application-layer protocol negotiated during the TLS handshake. See g_dtls_connection_get_negotiated_protocol().

Readable

peer-certificate

The connection’s peer’s certificate, after the TLS handshake has completed or failed. Note in particular that this is not yet set during the emission of #GDtlsConnection::accept-certificate.

(You can watch for a #GObject::notify signal on this property to detect when a handshake has occurred.)

Readable

peer-certificate-errors

The errors noticed while verifying #GDtlsConnection:peer-certificate. Normally this should be 0, but it may not be if #GDtlsClientConnection:validation-flags is not TlsCertificateFlags::VALIDATE_ALL, or if #GDtlsConnection::accept-certificate overrode the default behavior.

GLib guarantees that if certificate verification fails, at least one error will be set, but it does not guarantee that all possible errors will be set. Accordingly, you may not safely decide to ignore any particular type of error. For example, it would be incorrect to mask TlsCertificateFlags::EXPIRED if you want to allow expired certificates, because this could potentially be the only error flag set even if other problems exist with the certificate.

Readable

protocol-version

The DTLS protocol version in use. See g_dtls_connection_get_protocol_version().

Readable

rehandshake-mode

The rehandshaking mode. See g_dtls_connection_set_rehandshake_mode().

Readable | Writeable | Construct

require-close-notify

Whether or not proper TLS close notification is required. See g_dtls_connection_set_require_close_notify().

Implementations

impl DtlsClientConnection

pub const NONE: Option<&'static DtlsClientConnection> = None

pub fn new( base_socket: &impl IsA<DatagramBased>, server_identity: Option<&impl IsA<SocketConnectable>>, ) -> Result<DtlsClientConnection, Error>

Creates a new #GDtlsClientConnection wrapping @base_socket which is assumed to communicate with the server identified by @server_identity.

base_socket

the #GDatagramBased to wrap

server_identity

the expected identity of the server

Returns

the new #GDtlsClientConnection, or None on error

Trait Implementations

impl Clone for DtlsClientConnection

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

type ParamSpec = ParamSpecObject

type SetValue = DtlsClientConnection

Preferred value to be used as setter for the associated ParamSpec.
