There was recently an instance where a user was confused by the deprecation warnings in the docs. They believed the warning applied to the immediately preceding function declarations, when it fact it applied to the following function declarations. https://mta.openssl.org/pipermail/openssl-users/2021-December/014665.html We clarify the wording to make it clear that the warning applies to the following functions.

=head1 NAME
|
|
|
|
DSA_dup_DH - create a DH structure out of DSA structure
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dsa.h>
|
|
|
|
The following functions have been deprecated since OpenSSL 3.0, and 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 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)>.
|
|
|
|
=head1 NOTE
|
|
|
|
Be careful to avoid small subgroup attacks when using this.
