21 * Identities
22 * ----------
23 *
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:
79c44b4e 32 * - a macro for the identity with the name OSSL_FUNC_'FOO' or derivatives
4c2883a9 33 * thereof (to be specified further down)
363b1e5d
DMSP		 34 * - a function signature typedef with the name OSSL_FUNC_'foo'_fn
35 * - a function pointer extractor function with the name OSSL_FUNC_'foo'

RL		 446 * The Key Management takes care of provider side key objects, and includes
447 * all current functionality to create them, destroy them, set parameters
448 * and key material, etc, essentially everything that manipulates the keys
449 * themselves and their parameters.
a94a3e0d 450 *
b305452f
RL		 451 * The key objects are commonly refered to as |keydata|, and it MUST be able
452 * to contain parameters if the key has any, the public key and the private
453 * key. All parts are optional, but their presence determines what can be
454 * done with the key object in terms of encryption, signature, and so on.
455 * The assumption from libcrypto is that the key object contains any of the
456 * following data combinations:
457 *
458 * - parameters only
459 * - public key only
460 * - public key + private key
461 * - parameters + public key
462 * - parameters + public key + private key
463 *
464 * What "parameters", "public key" and "private key" means in detail is left
465 * to the implementation. In the case of DH and DSA, they would typically
466 * include domain parameters, while for certain variants of RSA, they would
467 * typically include PSS or OAEP parameters.
