32  /* Key Exchange parameters */
45 The key exchange (OSSL_OP_KEYEXCH) operation enables providers to implement key
46 exchange algorithms and make them available to applications via
82 A key exchange algorithm implementation may not implement all of these functions.
87 A key exchange algorithm must also implement some mechanism for generating,
94 structure for holding context information during a key exchange operation.
96 exchange operation function calls.
100 OSSL_FUNC_keyexch_freectx() is passed a pointer to the provider side key exchange
104 OSSL_FUNC_keyexch_dupctx() should duplicate the provider side key exchange context in
109 OSSL_FUNC_keyexch_init() initialises a key exchange operation given a provider side key
110 exchange context in the I<ctx> parameter, and a pointer to a provider key object
120 It is also passed a previously initialised key exchange context in the I<ctx>
126 OSSL_FUNC_keyexch_derive() performs the actual key exchange itself by deriving a shared
128 A previously initialised key exchange context is passed in the I<ctx>
136 =head2 Key Exchange Parameters Functions
138 OSSL_FUNC_keyexch_set_ctx_params() sets key exchange parameters associated with the
139 given provider side key exchange context I<ctx> to I<params>,
140 see L</Common Key Exchange parameters>.
144 OSSL_FUNC_keyexch_get_ctx_params() gets key exchange parameters associated with the
145 given provider side key exchange context I<ctx> into I<params>,
