    X.509 extensions are a general representation, with three properties: an identifier, a critical flag, and the encoded value. The specific data contained in the encoded value is determined by the value of the identifier stored in oid.

    This value enables Extensions to store the value of all extensions in a certificate, even ones it does not understand. A number of extensions have built-in support, and can be decoded directly from an Extension value. These are:

    Users can write their own types by using a similar approach to these types, when it is necessary to add support for different X.509 extension.
