=head1 NAME
|
|
DSA_generate_key - generate DSA key pair
|
|
=head1 SYNOPSIS
|
|
#include <openssl/dsa.h>
|
|
int DSA_generate_key(DSA *a);
|
|
=head1 DESCRIPTION
|
|
DSA_generate_key() expects B<a> to contain DSA parameters. It generates
|
a new key pair and stores it in B<a-E<gt>pub_key> and B<a-E<gt>priv_key>.
|
|
The random generator must be seeded prior to calling DSA_generate_key().
|
If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
|
external circumstances (see L<RAND(7)>), the operation will fail.
|
|
=head1 RETURN VALUES
|
|
DSA_generate_key() returns 1 on success, 0 otherwise.
|
The error codes can be obtained by L<ERR_get_error(3)>.
