## Description

An interface which allows importing of certificates and keys. Each GcrImporter is registered with a set of PKCS#11 attributes to match stuff that it can import.

An importer gets passed a GcrParser and accesses the currently parsed item. To create a set of importers that can import the currently parsed item in a GcrParser, use `gcr_importer_create_for_parsed()`. The list of importers returned has the parsed item queued for import.

To queue additional items with a importer use `gcr_importer_queue_for_parsed()`. In addition you can try and queue an additional item with a set of importers using the `gcr_importer_queue_and_filter_for_parsed()`.

To start the import use `gcr_importer_import()` or the async variants.

Prepare for supplementing the given attributes before import. This means prompting the user for things like labels and the like. The attributes will contain attributes for values that the importer needs, either empty or prefilled with suggested values.

This method does not prompt the user, but rather just prepares the interaction that these are the attributes that are needed.

`interaction` : | the interaction
`attributes` : | attributes to supplement

### gcr_import_interaction_supplement ()

    GTlsInteractionResult gcr_import_interaction_supplement (GcrImportInteraction *interaction,

Supplement attributes before import. This means prompting the user for things like labels and the like. The needed attributes will have been passed to `gcr_import_interaction_supplement_prep()`.

This method prompts the user and fills in the attributes. If the user or cancellable cancels the operation the error should be set with `G_IO_ERROR_CANCELLED`.

`interaction` : | the interaction
`attributes` : | supplemented attributes
`cancellable` : | optional cancellable object
`error` : | location to store error on failure
Returns : | `G_TLS_INTERACTION_HANDLED` if successful or `G_TLS_INTERACTION_FAILED`

Asynchronously supplement attributes before import. This means prompting the user for things like labels and the like. The needed attributes will have been passed to `gcr_import_interaction_supplement_prep()`.

This method prompts the user and fills in the attributes.

`interaction` : | the interaction
`attributes` : | supplemented attributes
`cancellable` : | optional cancellable object
`callback` : | called when the operation completes
`user_data` : | data to be passed to the callback
