## Functions

### g_tls_password_new ()

    GTlsPassword *
    g_tls_password_new (GTlsPasswordFlags flags,
                        const gchar *description);

Create a new GTlsPassword object.

#### Parameters

flags | the password flags |
description | description of what the password is for |

#### Returns

The newly allocated password object.

[transfer full]

### g_tls_password_get_value ()

    const guchar *
    g_tls_password_get_value (GTlsPassword *password,
                              gsize *length);

Get the password value. If `length` is not `NULL` then it will be filled in with the length of the password value. (Note that the password value is not nul-terminated, so you can only pass `NULL` for `length` in contexts where you know the password will have a certain fixed length.)

#### Parameters

password | a GTlsPassword object |
length | location to place the length of the password. | [allow-none]

#### Returns

The password value (owned by the password object).

Since: 2.30

### g_tls_password_set_value ()

    void
    g_tls_password_set_value (GTlsPassword *password,
                              const guchar *value,
                              gssize length);

Set the value for this password. The `value` will be copied by the password object.

Specify the `length` , for a non-nul-terminated password. Pass -1 as `length` if using a nul-terminated password, and `length` will be calculated automatically. (Note that the terminating nul is not considered part of the password in this case.)

#### Parameters

password | a GTlsPassword object |
value | the new password value |
length | the length of the password, or -1 |

Since: 2.30

### g_tls_password_set_value_full ()

    void
    g_tls_password_set_value_full (GTlsPassword *password,
                                   guchar *value,
                                   gssize length,
                                   GDestroyNotify destroy);

Provide the value for this password.

The `value` will be owned by the password object, and later freed using the `destroy` function callback.

Specify the `length` , for a non-nul-terminated password. Pass -1 as `length` if using a nul-terminated password, and `length` will be calculated automatically. (Note that the terminating nul is not considered part of the password in this case.)

Virtual: set_value

#### Parameters

password | a GTlsPassword object |
value | the value for the password |
length | the length of the password, or -1 |
destroy | a function to use to free the password. | [allow-none]

Since: 2.30

### g_tls_password_get_description ()

    const gchar *
    g_tls_password_get_description (GTlsPassword *password);

    g_tls_password_set_description (GTlsPassword *password,
                                    const gchar *description);

Set a description string about what the password will be used for.

#### Parameters

password | a GTlsPassword object |
description | The description of the password |

Since: 2.30

### g_tls_password_get_flags ()

    GTlsPasswordFlags
    g_tls_password_get_flags (GTlsPassword *password);
