=head1 DESCRIPTION
and L<EVP_DigestVerify(3)>.
int (*check) (EVP_PKEY *pkey);
+ int (*public_check) (EVP_PKEY *pkey);
+ int (*param_check) (EVP_PKEY *pkey);
-The check() method is used to validate a key-pair for a given B<pkey>. It
-could be called by L<EVP_PKEY_check(3)>.
+The check(), public_check() and param_check() methods are used to validate a
+key-pair, the public component and parameters respectively for a given B<pkey>.
+They could be called by L<EVP_PKEY_check(3)>, L<EVP_PKEY_public_check(3)> and
+L<EVP_PKEY_param_check(3)> respectively.
=head2 Functions
EVP_PKEY_meth_add0() adds B<pmeth> to the user defined stack of methods.
+EVP_PKEY_meth_remove() removes an B<EVP_PKEY_METHOD> object added by
+EVP_PKEY_meth_add0().
+
The EVP_PKEY_meth_set functions set the corresponding fields of
B<EVP_PKEY_METHOD> structure with the arguments passed.
EVP_PKEY_meth_add0() returns 1 if method is added successfully or 0
if an error occurred.
+EVP_PKEY_meth_remove() returns 1 if method is removed successfully or
+0 if an error occurred.
+
All EVP_PKEY_meth_set and EVP_PKEY_meth_get functions have no return
values. For the 'get' functions, function pointers are returned by
arguments.
