- DH * DSA_dup_DH(const DSA *r);
+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)>:
+
+ DH *DSA_dup_DH(const DSA *r);
=head1 DESCRIPTION
+The function described on this page is deprecated. There is no direct
+replacement, applications should use the EVP_PKEY APIs for Diffie-Hellman
+operations.
+
DSA_dup_DH() duplicates DSA parameters/keys as DH parameters/keys. q
is lost during that conversion, but the resulting DH parameters
contain its length.
-=head1 RETURN VALUE
+=head1 RETURN VALUES
DSA_dup_DH() returns the new B<DH> structure, and NULL on error. The
error codes can be obtained by L<ERR_get_error(3)>.
L<DH_new(3)>, L<DSA_new(3)>, L<ERR_get_error(3)>
+=head1 HISTORY
+
+This function was deprecated in OpenSSL 3.0.
