23  * ----------
24  *
25  * All series start with 1, to allow 0 to be an array terminator.
26  * For any FUNC identity, we also provide a function signature typedef
27  * and a static inline function to extract a function pointer from a
28  * OSSL_DISPATCH element in a type safe manner.
29  *
30  * Names:
31  * for any function base name 'foo' (uppercase form 'FOO'), we will have
32  * the following:
33  * - a macro for the identity with the name OSSL_FUNC_'FOO' or derivatives
34  *   thereof (to be specified further down)
35  * - a function signature typedef with the name OSSL_FUNC_'foo'_fn
36  * - a function pointer extractor function with the name OSSL_FUNC_'foo'
37  */

40  * Helper macro to create the function signature typedef and the extractor
41  * |type| is the return-type of the function, |name| is the name of the
42  * function to fetch, and |args| is a parenthesized list of parameters
43  * for the function (that is, it is |name|'s function signature).
44  * Note: This is considered a "reserved" internal macro. Applications should
45  * not use this or assume its existence.

507  * Key management
508  *
509  * The Key Management takes care of provider side key objects, and includes
510  * all current functionality to create them, destroy them, set parameters
511  * and key material, etc, essentially everything that manipulates the keys
512  * themselves and their parameters.
513  *
514  * The key objects are commonly refered to as |keydata|, and it MUST be able
515  * to contain parameters if the key has any, the public key and the private
516  * key.  All parts are optional, but their presence determines what can be
517  * done with the key object in terms of encryption, signature, and so on.
518  * The assumption from libcrypto is that the key object contains any of the
519  * following data combinations:
520  *
521  * - parameters only
522  * - public key only
523  * - public key + private key
524  * - parameters + public key
525  * - parameters + public key + private key

528  * to the implementation.  In the case of DH and DSA, they would typically

530  * typically include PSS or OAEP parameters.

537  * present in a key object: OSSL_FUNC_keymgmt_has_parameters(),
