If something was "present in all versions" of SSLeay, or if it was added to a version of SSLeay (and therefore predates OpenSSL), remove mention of it. Documentation history now starts with OpenSSL. Remove mention of all history before OpenSSL 0.9.8, inclusive. Remove all AUTHOR sections. Reviewed-by: Tim Hudson <tjh@openssl.org>

=head1 NAME
|
|
|
|
DSA_dup_DH - create a DH structure out of DSA structure
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dsa.h>
|
|
|
|
DH * DSA_dup_DH(const DSA *r);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
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
|
|
|
|
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.
