  24  * All series start with 1, to allow 0 to be an array terminator.
  25  * For any FUNC identity, we also provide a function signature typedef
  26  * and a static inline function to extract a function pointer from a
  27  * OSSL_DISPATCH element in a type safe manner.
  28  *
  29  * Names:
  30  * for any function base name 'foo' (uppercase form 'FOO'), we will have
  31  * the following:
  32  * - a macro for the identity with the name OSSL_FUNC_'FOO' or derivatives
  33  *   thereof (to be specified further down)
  34  * - a function signature typedef with the name OSSL_FUNC_'foo'_fn
  35  * - a function pointer extractor function with the name OSSL_FUNC_'foo'
  36  */

  39  * Helper macro to create the function signature typedef and the extractor
  40  * |type| is the return-type of the function, |name| is the name of the
  41  * function to fetch, and |args| is a parenthesized list of parameters
  42  * for the function (that is, it is |name|'s function signature).

 422  * Key management
 423  *
 424  * The Key Management takes care of provider side key objects, and includes
 425  * all current functionality to create them, destroy them, set parameters
 426  * and key material, etc, essentially everything that manipulates the keys
 427  * themselves and their parameters.
 428  *
 429  * The key objects are commonly refered to as |keydata|, and it MUST be able
 430  * to contain parameters if the key has any, the public key and the private
 431  * key.  All parts are optional, but their presence determines what can be
 432  * done with the key object in terms of encryption, signature, and so on.
 433  * The assumption from libcrypto is that the key object contains any of the
 434  * following data combinations:
 435  *
 436  * - parameters only
 437  * - public key only
 438  * - public key + private key
 439  * - parameters + public key
 440  * - parameters + public key + private key
 441  *
 442  * What "parameters", "public key" and "private key" means in detail is left
 443  * to the implementation.  In the case of DH and DSA, they would typically
 444  * include domain parameters, while for certain variants of RSA, they would
 445  * typically include PSS or OAEP parameters.
 446  *
 447  * Key objects are created with OSSL_FUNC_keymgmt_new() and destroyed with
 448  * OSSL_FUNC_keymgmt_free().  Key objects can have data filled in with
 449  * OSSL_FUNC_keymgmt_import().
 450  *
 451  * Three functions are made available to check what selection of data is
 452  * present in a key object: OSSL_FUNC_keymgmt_has_parameters(),
 453  * OSSL_FUNC_keymgmt_has_public_key(), and OSSL_FUNC_keymgmt_has_private_key(),
