=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 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.
