## Detailed Description

TlsCertificate - TLS certificate.

A certificate used for TLS authentication and encryption. This can represent either a certificate only (eg, the certificate received by a client from a server), or the combination of a certificate and a private key (which is needed when acting as a TlsServerConnection).

## Member Function Documentation

static Glib::RefPtr<TlsCertificate> Gio::TlsCertificate::create | ( | const std::string & | file | ) |
| static

Creates a TlsCertificate from the PEM-encoded data in file.

The returned certificate will be the first certificate found in file. As of GLib 2.44, if file contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the TlsCertificate::property_issuer() property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

If file cannot be read or parsed, the function will return `nullptr` and set error. Otherwise, this behaves like g_tls_certificate_new_from_pem().

Since glibmm 2.28:

Parameters

  file | File containing a PEM-encoded certificate to import.

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

static Glib::RefPtr<TlsCertificate> Gio::TlsCertificate::create | ( | const std::string & | cert_file,
|  | const std::string & | key_file
| ) |  |
| static

Creates a TlsCertificate from the PEM-encoded data in cert_file and key_file.

The returned certificate will be the first certificate found in cert_file. As of GLib 2.44, if cert_file contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the TlsCertificate::property_issuer() property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

If either file cannot be read or parsed, the function will return `nullptr` and set error. Otherwise, this behaves like g_tls_certificate_new_from_pem().

Since glibmm 2.28:

Parameters

  cert_file | File containing one or more PEM-encoded certificates to import.
  key_file | File containing a PEM-encoded private key to import.

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

static Glib::RefPtr<TlsCertificate> Gio::TlsCertificate::create_from_pem | ( | const std::string & | data,
|  | gssize | length = `-1`
| ) |  |
| static

Creates a TlsCertificate from the PEM-encoded data in data.

If data includes both a certificate and a private key, then the returned certificate will include the private key data as well. (See the TlsCertificate::property_private_key_pem() property for information about supported formats.)

The returned certificate will be the first certificate found in data. As of GLib 2.44, if data contains more certificates it will try to load a certificate chain. All certificates will be verified in the order found (top-level certificate should be the last one in the file) and the TlsCertificate::property_issuer() property of each certificate will be set accordingly if the verification succeeds. If any certificate in the chain cannot be verified, the first certificate in the file will still be returned.

Since glibmm 2.28:

Parameters

  data | PEM-encoded certificate data.
  length | The length of data, or -1 if it's 0-terminated.

Returns
  The new certificate, or `nullptr` if data is invalid.

static std::vector< Glib::RefPtr<TlsCertificate> > Gio::TlsCertificate::create_list_from_file | ( | const std::string & | file | ) |
| static

Creates one or more TlsCertificates from the PEM-encoded data in file.

If file cannot be read or parsed, the function will return `nullptr` and set error. If file does not contain any PEM-encoded certificates, this will return an empty list and not set error.

Since glibmm 2.28:

Parameters

  file | File containing PEM-encoded certificates to import.

Returns
  A List containing TlsCertificate objects. You must free the list and its contents when you are done with it.

Exceptions

  Glib::Error |

Glib::RefPtr<TlsCertificate> Gio::TlsCertificate::get_issuer | ( |  | ) |

Gets the TlsCertificate representing cert's issuer, if known.

Since glibmm 2.28:

Returns
  The certificate of cert's issuer, or `nullptr` if cert is self-signed or signed with an unknown certificate.

Glib::RefPtr<const TlsCertificate> Gio::TlsCertificate::get_issuer | ( |  | ) | const

Gets the TlsCertificate representing cert's issuer, if known.

Since glibmm 2.28:

Returns
  The certificate of cert's issuer, or `nullptr` if cert is self-signed or signed with an unknown certificate.

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

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

GTlsCertificate* Gio::TlsCertificate::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GTlsCertificate* Gio::TlsCertificate::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GTlsCertificate* Gio::TlsCertificate::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gio::TlsCertificate::is_same | ( | const Glib::RefPtr< const TlsCertificate >& | cert_two | ) | const

Check if two TlsCertificate objects represent the same certificate.

The raw DER byte data of the two certificates are checked for equality. This has the effect that two certificates may compare equal even if their TlsCertificate::property_issuer(), TlsCertificate::property_private_key(), or TlsCertificate::property_private_key_pem() properties differ.

Since glibmm 2.34:

Parameters

  cert_two | Second certificate to compare.

Returns
  Whether the same or not.

TlsCertificate& Gio::TlsCertificate::operator= | ( | TlsCertificate&& | src | ) |
| noexcept

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Glib::ByteArray> > Gio::TlsCertificate::property_certificate | ( |  | ) | const

The DER (binary) encoded representation of the certificate.

This property and the TlsCertificate::property_certificate_pem() property represent the same data, just in different forms.

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.

Glib::PropertyProxy_ReadOnly< std::string > Gio::TlsCertificate::property_certificate_pem | ( |  | ) | const

The PEM (ASCII) encoded representation of the certificate.

This property and the TlsCertificate::property_certificate() property represent the same data, just in different forms.

Since glibmm 2.28:

Default value: ""

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

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<TlsCertificate> > Gio::TlsCertificate::property_issuer | ( |  | ) | const

A TlsCertificate representing the entity that issued this certificate.

If `nullptr`, this means that the certificate is either self-signed, or else the certificate of the issuer is not available.

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.

TlsCertificateFlags Gio::TlsCertificate::verify | ( | const Glib::RefPtr< const SocketConnectable >& | identity,
|  | const Glib::RefPtr< const TlsCertificate >& | trusted_ca
| ) |  | const

This verifies cert and returns a set of TlsCertificateFlags indicating any problems found with it.

This can be used to verify a certificate outside the context of making a connection, or to check a certificate against a CA that is not part of the system CA database.

If identity is not `nullptr`, cert's name(s) will be compared against it, and TLS_CERTIFICATE_BAD_IDENTITY will be set in the return value if it does not match. If identity is `nullptr`, that bit will never be set in the return value.

If trusted_ca is not `nullptr`, then cert (or one of the certificates in its chain) must be signed by it, or else TLS_CERTIFICATE_UNKNOWN_CA will be set in the return value. If trusted_ca is `nullptr`, that bit will never be set in the return value.

(All other TlsCertificateFlags values will always be set or unset as appropriate.)

Since glibmm 2.28:

Parameters

  identity | The expected peer identity.
  trusted_ca | The certificate of a trusted authority.

Returns
  The appropriate TlsCertificateFlags.

TlsCertificateFlags Gio::TlsCertificate::verify | ( | const Glib::RefPtr< const SocketConnectable >& | identity | ) | const

A verify() convenience overload.

TlsCertificateFlags Gio::TlsCertificate::verify | ( | const Glib::RefPtr< const TlsCertificate >& | trusted_ca | ) | const

A verify() convenience overload.

TlsCertificateFlags Gio::TlsCertificate::verify | ( |  | ) | const

A verify() convenience overload.

virtual TlsCertificateFlags Gio::TlsCertificate::verify_vfunc | ( | const Glib::RefPtr< const SocketConnectable >& | identity,
