|
|---|
| 5 | DSA_generate_key - generate DSA key pair
|
|---|
| 6 |
|

| 7 | =head1 SYNOPSIS
|
|---|
| 8 |
|
|---|
| 9 | #include <openssl/dsa.h>
|
|---|
| 10 |
|
|---|
| 11 | The following functions have been deprecated since OpenSSL 3.0, and can be
|
|---|
| 12 | hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
|
|---|
| 13 | see L<openssl_user_macros(7)>:
|
|---|
| 14 |
|
|---|
| 15 | int DSA_generate_key(DSA *a);
|
|---|
| 16 |
|
|---|
| 17 | =head1 DESCRIPTION
|
|---|
| 18 |
|
|---|
| 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)>.
|
|---|
| 22 |
|
|---|
| 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>.
|
|---|
| 25 |
|
|---|
| 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.
|
|---|
| 29 |
|
|---|
| 30 | =head1 RETURN VALUES
|
|---|
| 31 |
|
|---|
| 32 | DSA_generate_key() returns 1 on success, 0 otherwise.
|
|---|
| 33 | The error codes can be obtained by L<ERR_get_error(3)>.
