  /*-
   * Key management
   *
   * The Key Management takes care of provider side key objects, and includes
   * all current functionality to create them, destroy them, set parameters
   * and key material, etc, essentially everything that manipulates the keys
   * themselves and their parameters.
   *
   * The key objects are commonly refered to as |keydata|, and it MUST be able
   * to contain parameters if the key has any, the public key and the private
   * key.  All parts are optional, but their presence determines what can be
   * done with the key object in terms of encryption, signature, and so on.
   * The assumption from libcrypto is that the key object contains any of the
   * following data combinations:
   *
   * - parameters only
   * - public key only
   * - public key + private key
   * - parameters + public key
   * - parameters + public key + private key
   *
   * What "parameters", "public key" and "private key" means in detail is left
   * to the implementation.  In the case of DH and DSA, they would typically
   * include domain parameters, while for certain variants of RSA, they would
   * typically include PSS or OAEP parameters.
   *
   * Key objects are created with OP_keymgmt_new() and destroyed with
   * Op_keymgmt_free().  Key objects can have data filled in with
   * OP_keymgmt_import().
   *
   * Three functions are made available to check what selection of data is
   * present in a key object: OP_keymgmt_has_parameters(),
   * OP_keymgmt_has_public_key(), and OP_keymgmt_has_private_key(),
