#### Description [src]

    class Gcr.Parser : GObject.Object
    {
      /* No available fields */
    }

A parser for parsing various types of files or data.

A `GcrParser` can parse various certificate and key files such as OpenSSL PEM files, DER encoded certifictes, PKCS#8 keys and so on. Each various format is identified by a value in the `GcrDataFormat` enumeration.

In order to parse data, a new parser is created with `gcr_parser_new()` and then the `GcrParser::authenticate` and `GcrParser::parsed` signals should be connected to. Data is then fed to the parser via `gcr_parser_parse_data()` or `gcr_parser_parse_stream()`.

During the `GcrParser::parsed` signal the attributes that make up the currently parsed item can be retrieved using the `gcr_parser_get_parsed_attributes()` function.

#### Constructors

###### gcr_parser_new

Create a new `GcrParser`.

#### Instance methods

###### gcr_parser_add_password

Add a password to the set of passwords to try when parsing locked or encrypted items. This is usually called from the `GcrParser::authenticate` signal.

since: 3

###### gcr_parser_format_disable

Disable parsing of the given format. Use `GCR_FORMAT_ALL` to disable all the formats.

since: 3

###### gcr_parser_format_enable

Enable parsing of the given format. Use `GCR_FORMAT_ALL` to enable all the formats.

since: 3

###### gcr_parser_format_supported

Check whether the given format is supported by the parser.

since: 3

###### gcr_parser_get_filename

Get the filename of the parser item.

since: 3

###### gcr_parser_get_parsed

Get the currently parsed item.

since: 3

###### gcr_parser_get_parsed_attributes

Get the attributes which make up the currently parsed item. This is generally only valid during the `GcrParser::parsed` signal.

since: 3

###### gcr_parser_get_parsed_block

Get the raw data block that represents this parsed object. This is only valid during the `GcrParser::parsed` signal.

since: 3

###### gcr_parser_get_parsed_bytes

Get the raw data block that represents this parsed object. This is only valid during the `GcrParser::parsed` signal.

since: 3

###### gcr_parser_get_parsed_description

Get a description for the type of the currently parsed item. This is generally only valid during the `GcrParser::parsed` signal.

since: 3

###### gcr_parser_get_parsed_format

Get the format of the raw data block that represents this parsed object. This corresponds with the data returned from gcr_parser_get_parsed_block().

since: 3

###### gcr_parser_get_parsed_label

Get the label of the currently parsed item. This is generally only valid during the `GcrParser::parsed` signal.

since: 3

###### gcr_parser_parse_bytes

Parse the data. The `GcrParser::parsed` and `GcrParser::authenticate` signals may fire during the parsing.

since: 3

###### gcr_parser_parse_data

Parse the data. The `GcrParser::parsed` and `GcrParser::authenticate` signals may fire during the parsing.

since: 3

###### gcr_parser_parse_stream

Parse items from the data in a `GInputStream`. This function may block while reading from the input stream. Use `gcr_parser_parse_stream_async()` for a non-blocking variant.

since: 3

###### gcr_parser_parse_stream_async

Parse items from the data in a `GInputStream`. This function completes asyncronously and doesn’t block.

since: 3

###### gcr_parser_parse_stream_finish

Complete an operation to parse a stream.

since: 3

###### gcr_parser_set_filename

Sets the filename of the parser item.

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

#### Properties

###### Gcr.Parser:parsed-attributes

Get the attributes that make up the currently parsed item. This is generally only valid during a `GcrParser::parsed` signal.

since: 3

###### Gcr.Parser:parsed-description

The description of the type of the currently parsed item. This is generally only valid during a `GcrParser::parsed` signal.

since: 3

###### Gcr.Parser:parsed-label

The label of the currently parsed item. This is generally only valid during a `GcrParser::parsed` signal.

since: 3

#### Signals

###### Gcr.Parser::authenticate

This signal is emitted when an item needs to be unlocked or decrypted before it can be parsed. The `count` argument specifies the number of times the signal has been emitted for a given item. This can be used to display a message saying the previous password was incorrect.

since: 3

###### Gcr.Parser::parsed

This signal is emitted when an item is sucessfully parsed. To access the information about the item use the gcr_parser_get_parsed_label(), `gcr_parser_get_parsed_attributes()` and `gcr_parser_get_parsed_description()` functions.

since: 3

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
