### nm_secret_agent_error_quark ()

    GQuark
    nm_secret_agent_error_quark (void);

### NMSecretAgentGetSecretsFunc ()

    void
    (*NMSecretAgentGetSecretsFunc) (NMSecretAgent *agent,
                                    NMConnection *connection,
                                    GHashTable *secrets,
                                    GError *error,
                                    gpointer user_data);

Called as a result of a request by NM to retrieve secrets. When the NMSecretAgent subclass has finished retrieving secrets and is ready to return them, or to return an error, this function should be called with those secrets or the error.

To easily create the hash table to return the Wi-Fi PSK, you could do something like this:

Example 1. Creating a secrets hash

    NMConnection *secrets;
    NMSettingWirelessSecurity *s_wsec;
    GHashTable *secrets_hash;

    secrets = nm_connection_new ();
    s_wsec = (NMSettingWirelessSecurity *) nm_setting_wireless_security_new ();
    g_object_set (G_OBJECT (s_wsec),
                  NM_SETTING_WIRELESS_SECURITY_PSK, "my really cool PSK",
                  NULL);
    nm_connection_add_setting (secrets, NM_SETTING (s_wsec));
    secrets_hash = nm_connection_to_hash (secrets, NM_SETTING_HASH_FLAG_ALL);

    (call the NMSecretAgentGetSecretsFunc with secrets_hash)

    g_object_unref (secrets);
    g_hash_table_unref (secrets_hash);

#### Parameters

agent | the secret agent object |
connection | the connection for which secrets were requested, note that this object will be unrefed after the callback has returned, use `g_object_ref()`/`g_object_unref()` if you want to use this object after the callback has returned. | [transfer none]

secrets

the GHashTable containing the requested secrets in the same format as an NMConnection hash (as created by `nm_connection_to_hash()` for example). Each key in `secrets` should be the name of a NMSetting object (like "802-11-wireless-security") and each value should be a GHashTable. The sub-hashes map string:GValue where the string is the setting property name (like "psk") and the value is the secret.

error | if the secrets request failed, give a descriptive error here |
user_data | caller-specific data to be passed to the function |

### NMSecretAgentSaveSecretsFunc ()

    void
    (*NMSecretAgentSaveSecretsFunc) (NMSecretAgent *agent,

                                     gpointer user_data);

Called as a result of a request by NM to save secrets. When the NMSecretAgent subclass has finished saving the secrets, this function should be called.

#### Parameters

agent | the secret agent object |
connection | the connection for which secrets were to be saved, note that this object will be unrefed after the callback has returned, use `g_object_ref()`/`g_object_unref()` if you want to use this object after the callback has returned. | [transfer none]
error | if the saving secrets failed, give a descriptive error here |
user_data | caller-specific data to be passed to the function |

### NMSecretAgentDeleteSecretsFunc ()

    void
    (*NMSecretAgentDeleteSecretsFunc) (NMSecretAgent *agent,
                                       NMConnection *connection,
                                       GError *error,
                                       gpointer user_data);

Called as a result of a request by NM to delete secrets. When the NMSecretAgent subclass has finished deleting the secrets, this function should be called.

#### Parameters

agent | the secret agent object |
connection | the connection for which secrets were to be deleted, note that this object will be unrefed after the callback has returned, use `g_object_ref()`/`g_object_unref()` if you want to use this object after the callback has returned. | [transfer none]
error | if the deleting secrets failed, give a descriptive error here |
user_data | caller-specific data to be passed to the function |

### nm_secret_agent_register ()

    gboolean
    nm_secret_agent_register (NMSecretAgent *self);

Registers the NMSecretAgent with the NetworkManager secret manager, indicating to NetworkManager that the agent is able to provide and save secrets for connections on behalf of its user. Registration is an asynchronous operation and its success or failure is indicated via the 'registration-result' signal.

#### Parameters

self | a NMSecretAgent |

#### Returns

a new `TRUE` if registration was successfully requested (this does not mean registration itself was successful), `FALSE` if registration was not successfully requested.

### nm_secret_agent_unregister ()

    gboolean
    nm_secret_agent_unregister (NMSecretAgent *self);

Unregisters the NMSecretAgent with the NetworkManager secret manager, indicating to NetworkManager that the agent is will no longer provide or store secrets on behalf of this user.

#### Parameters

self | a NMSecretAgent |

#### Returns

a new `TRUE` if unregistration was successful, `FALSE` if it was not.

### nm_secret_agent_get_registered ()

    gboolean
    nm_secret_agent_get_registered (NMSecretAgent *self);

#### Parameters

self | a NMSecretAgent |

#### Returns

a `TRUE` if the agent is registered, `FALSE` if it is not.

### nm_secret_agent_get_secrets ()

    void
    nm_secret_agent_get_secrets (NMSecretAgent *self,
                                 NMConnection *connection,

## Types and Values

### NM_SECRET_AGENT_ERROR

    #define NM_SECRET_AGENT_ERROR         (nm_secret_agent_error_quark ())

### enum NMSecretAgentError

NMSecretAgentError values are passed by secret agents back to NetworkManager when they encounter problems retrieving secrets on behalf of NM.

#### Members

NM_SECRET_AGENT_ERROR_NOT_AUTHORIZED | the caller (ie, NetworkManager) is not authorized to make this request |
NM_SECRET_AGENT_ERROR_INVALID_CONNECTION | the connection for which secrets were requested could not be found |
NM_SECRET_AGENT_ERROR_USER_CANCELED | the request was canceled by the user |
NM_SECRET_AGENT_ERROR_AGENT_CANCELED | the agent canceled the request because it was requested to do so by NetworkManager |
NM_SECRET_AGENT_ERROR_INTERNAL_ERROR | some internal error in the agent caused the request to fail |
NM_SECRET_AGENT_ERROR_NO_SECRETS | the agent cannot find any secrets for this connection |

### enum NMSecretAgentCapabilities

NMSecretAgentCapabilities indicate various capabilities of the agent.

#### Members

NM_SECRET_AGENT_CAPABILITY_NONE | the agent supports no special capabilities |
NM_SECRET_AGENT_CAPABILITY_VPN_HINTS | the agent supports sending hints given by the `get_secrets` class method to VPN plugin authentication dialogs. |
NM_SECRET_AGENT_CAPABILITY_LAST | bounds checking value; should not be used. |

Since: 0.9.10

### enum NMSecretAgentGetSecretsFlags

NMSecretAgentGetSecretsFlags values modify the behavior of a GetSecrets request.

#### Members

NM_SECRET_AGENT_GET_SECRETS_FLAG_NONE | no special behavior; by default no user interaction is allowed and requests for secrets are fulfilled from persistent storage, or if no secrets are available an error is returned. |
NM_SECRET_AGENT_GET_SECRETS_FLAG_ALLOW_INTERACTION | allows the request to interact with the user, possibly prompting via UI for secrets if any are required, or if none are found in persistent storage. |
NM_SECRET_AGENT_GET_SECRETS_FLAG_REQUEST_NEW | explicitly prompt for new secrets from the user. This flag signals that NetworkManager thinks any existing secrets are invalid or wrong. This flag implies that interaction is allowed. |
NM_SECRET_AGENT_GET_SECRETS_FLAG_USER_REQUESTED | set if the request was initiated by user-requested action via the D-Bus interface, as opposed to automatically initiated by NetworkManager in response to (for example) scan results or carrier changes. |

### NM_SECRET_AGENT_IDENTIFIER

    #define NM_SECRET_AGENT_IDENTIFIER          "identifier"

### NM_SECRET_AGENT_AUTO_REGISTER

    #define NM_SECRET_AGENT_AUTO_REGISTER       "auto-register"

### NM_SECRET_AGENT_REGISTERED

    #define NM_SECRET_AGENT_REGISTERED          "registered"

### NM_SECRET_AGENT_CAPABILITIES

    #define NM_SECRET_AGENT_CAPABILITIES        "capabilities"

### NM_SECRET_AGENT_REGISTRATION_RESULT

    #define NM_SECRET_AGENT_REGISTRATION_RESULT "registration-result"

## Property Details

### The `“auto-register”` property

      “auto-register”            gboolean

If TRUE, the agent will attempt to automatically register itself after it is created (via an idle handler) and to re-register itself if NetworkManager restarts. If FALSE, the agent does not automatically register with NetworkManager, and `nm_secret_agent_register()` must be called. If 'auto-register' is TRUE, calling `nm_secret_agent_unregister()` will suppress auto-registration until `nm_secret_agent_register()` is called, which re-enables auto-registration.

Flags: Read / Write / Construct

Default value: TRUE

### The `“capabilities”` property

      “capabilities”             NMSecretAgentCapabilities

A bitfield of `NMSecretAgentCapabilities`.

Flags: Read / Write / Construct

### The `“identifier”` property

      “identifier”               gchar *

Identifies this agent; only one agent in each user session may use the same identifier. Identifier formatting follows the same rules as D-Bus bus names with the exception that the ':' character is not allowed. The valid set of characters is "A-Z[0-9]_-." and the identifier is limited in length to 255 characters with a minimum of 3 characters. An example valid identifier is 'org.gnome.nm-applet' (without quotes).

Flags: Read / Write / Construct Only

Default value: NULL

### The `“registered”` property

      “registered”               gboolean

`TRUE` if the agent is registered with NetworkManager, `FALSE` if not.

Flags: Read

Default value: FALSE

## Signal Details

### The `“registration-result”` signal

    void
    user_function (NMSecretAgent *agent,
                   gpointer       error,
                   gpointer       user_data)

Indicates the result of a registration request; if `error` is NULL the request was successful.

#### Parameters

agent | the agent that received the signal |
error | the error, if any, that occured while registering |
user_data | user data set when the signal handler was connected. |

Flags: Run First
