示例1: parseKeyDescriptor
/**
* This function parses a KeyDescriptor element. It currently only supports keys with a single
* X509 certificate.
*
* The associative array for a key can contain:
* - 'encryption': Indicates wheter this key can be used for encryption.
* - 'signing': Indicates wheter this key can be used for signing.
* - 'type: The type of the key. 'X509Certificate' is the only key type we support.
* - 'X509Certificate': The contents of the first X509Certificate element (if the type is 'X509Certificate ').
*
* @param $kd The KeyDescriptor element.
* @return Associative array describing the key, or NULL if this is an unsupported key.
