It provides a set of of functions used by OpenSSL for the +implementation of the various DH capabilities. + +DH_meth_new() creates a new B structure. It should be given a +unique B and a set of B. The B should be a NULL terminated +string, which will be duplicated and stored in the B object. It is +the callers responsibility to free the original string. The flags will be used +during the construction of a new B object based on this B. Any +new B object will have those flags set by default. + +DH_meth_dup() creates a duplicate copy of the B object passed as a +parameter. This might be useful for creating a new B based on an +existing one, but with some differences. + +DH_meth_free() destroys a B structure and frees up any memory +associated with it. + +DH_meth_get0_name() will return a pointer to the name of this DH_METHOD. This +is a pointer to the internal name string and so should not be freed by the +caller. DH_meth_set1_name() sets the name of the DH_METHOD to B. The +string is duplicated and the copy is stored in the DH_METHOD structure, so the +caller remains responsible for freeing the memory associated with the name. + +DH_meth_get_flags() returns the current value of the flags associated with this +DH_METHOD. DH_meth_set_flags() provides the ability to set these flags. + +The functions DH_meth_get0_app_data() and DH_meth_set0_app_data() provide the +ability to associate implementation specific data with the DH_METHOD. It is +the application's responsibility to free this data before the DH_METHOD is +freed via a call to DH_meth_free(). + +DH_meth_get_generate_key() and DH_meth_set_generate_key() get and set the +function used for generating a new DH key pair respectively. This function will +be called in response to the application calling DH_generate_key(). The +parameter for the function has the same meaning as for DH_generate_key(). + +DH_meth_get_compute_key() and DH_meth_set_compute_key() get and set the +function used for computing a new DH shared secret respectively. This function +will be called in response to the application calling DH_compute_key(). The +parameters for the function have the same meaning as for DH_compute_key(). + +DH_meth_get_bn_mod_exp() and DH_meth_set_bn_mod_exp() get and set the function +used for computing the following value: + + r = a ^ p mod m + +This function will be called by the default OpenSSL function for +DH_generate_key(). The result is stored in the B parameter. This function +may be NULL unless using the default generate key function, in which case it +must be present. + +DH_meth_get_init() and DH_meth_set_init() get and set the function used +for creating a new DH instance respectively. This function will be +called in response to the application calling DH_new() (if the current default +DH_METHOD is this one) or DH_new_method(). The DH_new() and DH_new_method() +functions will allocate the memory for the new DH object, and a pointer to this +newly allocated structure will be passed as a parameter to the function. This +function may be NULL. + +DH_meth_get_finish() and DH_meth_set_finish() get and set the function used +for destroying an instance of a DH object respectively. This function will be +called in response to the application calling DH_free(). A pointer to the DH +to be destroyed is passed as a parameter. The destroy function should be used +for DH implementation specific clean up. The memory for the DH itself should +not be freed by this function. This function may be NULL. + +DH_meth_get_generate_params() and DH_meth_set_generate_params() get and set the +function used for generating DH parameters respectively. This function will be +called in response to the application calling DH_generate_parameters_ex() (or +DH_generate_parameters()). The parameters for the function have the same +meaning as for DH_generate_parameters_ex(). This function may be NULL. + +=head1 RETURN VALUES + +DH_meth_new() and DH_meth_dup() return the newly allocated DH_METHOD object +or NULL on failure. + +DH_meth_get0_name() and DH_meth_get_flags() return the name and flags +associated with the DH_METHOD respectively. + +All other DH_meth_get_*() functions return the appropriate function pointer +that has been set in the DH_METHOD, or NULL if no such pointer has yet been +set. + +DH_meth_set1_name() and all DH_meth_set_*() functions return 1 on success or +0 on failure. + +=head1 SEE ALSO + +L, L, L, L, +L, L, L + +=head1 HISTORY + +The functions described here were added in OpenSSL version 1.1.0. + +=head1 COPYRIGHT + +Copyright 2016 The OpenSSL Project Authors.
