|  | =head1 NAME | 
|  |  | 
|  | DSA_generate_key - generate DSA key pair | 
|  |  | 
|  | =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)>: | 
|  |  | 
|  | int DSA_generate_key(DSA *a); | 
|  |  | 
|  | =head1 DESCRIPTION | 
|  |  | 
|  | All of the functions described on this page are deprecated. | 
|  | Applications should instead use L<EVP_PKEY_keygen_init(3)> and | 
|  | L<EVP_PKEY_keygen(3)> as described in L<EVP_PKEY-DSA(7)>. | 
|  |  | 
|  | 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)>. | 
|  |  |
