46 The MAC operation enables providers to implement mac algorithms and make
85 A mac algorithm implementation may not implement all of these functions.
94 structure for holding context information during a mac operation.
95 A pointer to this context will be passed back in a number of the other mac
100 OSSL_FUNC_mac_freectx() is passed a pointer to the provider side mac context in
106 OSSL_FUNC_mac_dupctx() should duplicate the provider side mac context in the
111 OSSL_FUNC_mac_init() initialises a mac operation given a newly created provider
112 side mac context in the I<mctx> parameter.  The I<params> are set before setting
113 the MAC I<key> of I<keylen> bytes.
115 OSSL_FUNC_mac_update() is called to supply data for MAC computation of a previously
116 initialised mac operation.
119 OSSL_FUNC_mac_update() may be called multiple times for a single mac operation.
121 OSSL_FUNC_mac_final() completes the MAC computation started through previous
124 The resulting MAC should be written to I<out> and the amount of data written
