5 DSA_generate_key - generate DSA key pair
9 #include <openssl/dsa.h>
11 Deprecated since OpenSSL 3.0, can be hidden entirely by defining
12 B<OPENSSL_API_COMPAT> with a suitable version value, see
13 L<openssl_user_macros(7)>:
15 int DSA_generate_key(DSA *a);
19 All of the functions described on this page are deprecated.
20 Applications should instead use L<EVP_PKEY_keygen_init(3)> and
21 L<EVP_PKEY_keygen(3)> as described in L<EVP_PKEY-DSA(7)>.
23 DSA_generate_key() expects B<a> to contain DSA parameters. It generates
24 a new key pair and stores it in B<a-E<gt>pub_key> and B<a-E<gt>priv_key>.
26 The random generator must be seeded prior to calling DSA_generate_key().
27 If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
28 external circumstances (see L<RAND(7)>), the operation will fail.
32 DSA_generate_key() returns 1 on success, 0 otherwise.
33 The error codes can be obtained by L<ERR_get_error(3)>.
37 L<DSA_new(3)>, L<ERR_get_error(3)>, L<RAND_bytes(3)>,
