5DSA_generate_key - generate DSA key pair

8
9 #include <openssl/dsa.h>
10
11 int DSA_generate_key(DSA *a);
12
13=head1 DESCRIPTION
14
15DSA_generate_key() expects B<a> to contain DSA parameters. It generates
16a new key pair and stores it in B<a-E<gt>pub_key> and B<a-E<gt>priv_key>.
17
18The random generator must be seeded prior to calling DSA_generate_key().
19If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
20external circumstances (see L<RAND(7)>), the operation will fail.
21
22=head1 RETURN VALUES
23
24DSA_generate_key() returns 1 on success, 0 otherwise.
25The error codes can be obtained by L<ERR_get_error(3)>.
