#include <openssl/rsa.h>
+Deprecated since OpenSSL 3.0, can be hidden entirely by defining
+B<OPENSSL_API_COMPAT> with a suitable version value, see
+L<openssl_user_macros(7)>:
+
int RSA_check_key_ex(RSA *rsa, BN_GENCB *cb);
int RSA_check_key(RSA *rsa);
=head1 DESCRIPTION
+Both of the functions described on this page are deprecated.
+Applications should instead use L<EVP_PKEY_public_check(3)>,
+L<EVP_PKEY_private_check(3)> and L<EVP_PKEY_pairwise_check(3)>.
+
RSA_check_key_ex() function validates RSA keys.
It checks that B<p> and B<q> are
in fact prime, and that B<n = p*q>.
=head1 HISTORY
+All of these functions were deprecated in OpenSSL 3.0.
+
RSA_check_key_ex() appeared after OpenSSL 1.0.2.
