fetched implicitly using default search criteria.
Implicit fetching can also occur with functions such as
-L<EVP_PKEY_CTX_derive_init_ex(3)> where a NULL algorithm parameter is
+L<EVP_PKEY_derive_init_ex(3)> where a NULL algorithm parameter is
supplied.
In this case an algorithm implementation is implicitly fetched using
default search criteria and an algorithm name that is consistent with
