## Interface PGPData

- All Superinterfaces:
    XMLStructure

      public interface PGPData
      extends XMLStructure

  A representation of the XML `PGPData` element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. A `PGPData` object is used to convey information related to PGP public key pairs and signatures on such keys. The XML Schema Definition is defined as:

          <element name="PGPData" type="ds:PGPDataType"/>
          <complexType name="PGPDataType">
            <choice>
              <sequence>
                <element name="PGPKeyID" type="base64Binary"/>
                <element name="PGPKeyPacket" type="base64Binary" minOccurs="0"/>
                <any namespace="##other" processContents="lax" minOccurs="0"
                 maxOccurs="unbounded"/>
              </sequence>
              <sequence>
                <element name="PGPKeyPacket" type="base64Binary"/>
                <any namespace="##other" processContents="lax" minOccurs="0"
                 maxOccurs="unbounded"/>
              </sequence>
            </choice>
          </complexType>

  A `PGPData` instance may be created by invoking one of the `newPGPData` methods of the `KeyInfoFactory` class, and passing it `byte` arrays representing the contents of the PGP public key identifier and/or PGP key material packet, and an optional list of elements from an external namespace.
  Since:
    1.6

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `List` | `getExternalElements()` Returns an `unmodifiable list` of `XMLStructure`s representing elements from an external namespace.
    `byte[]` | `getKeyId()` Returns the PGP public key identifier of this `PGPData` as defined in RFC 2440, section 11.2.
    `byte[]` | `getKeyPacket()` Returns the PGP key material packet of this `PGPData` as defined in RFC 2440, section 5.5.

- - ### Field Detail

    - #### TYPE

          static final String TYPE

      URI identifying the PGPData KeyInfo type: http://www.w3.org/2000/09/xmldsig#PGPData. This can be specified as the value of the `type` parameter of the `RetrievalMethod` class to describe a remote `PGPData` structure.

  - ### Method Detail

    - #### getKeyId

          byte[] getKeyId()

      Returns the PGP public key identifier of this `PGPData` as defined in RFC 2440, section 11.2.
      Returns:
        the PGP public key identifier (may be `null` if not specified). Each invocation of this method returns a new clone to protect against subsequent modification.

    - #### getKeyPacket

          byte[] getKeyPacket()

      Returns the PGP key material packet of this `PGPData` as defined in RFC 2440, section 5.5.
      Returns:
        the PGP key material packet (may be `null` if not specified). Each invocation of this method returns a new clone to protect against subsequent modification.

    - #### getExternalElements

          List getExternalElements()

      Returns an `unmodifiable list` of `XMLStructure`s representing elements from an external namespace.
      Returns:
        an unmodifiable list of `XMLStructure`s (may be empty, but never `null`)
