|

| 5 | DSA_new, DSA_free - allocate and free DSA objects
|

| 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 | DSA* DSA_new(void);
|
|---|
| 16 |
|
|---|
| 17 | void DSA_free(DSA *dsa);
|

| 19 | =head1 DESCRIPTION
|
|---|
| 20 |
|
|---|
| 21 | All of the functions described on this page are deprecated.
|
|---|
| 22 | Applications should instead use L<EVP_PKEY_new(3)> and L<EVP_PKEY_free(3)>.
|
|---|
| 23 |
|
|---|
| 24 | DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
|
|---|
| 25 | calling DSA_new_method(NULL).
|
|---|
| 26 |
|
|---|
| 27 | DSA_free() frees the B<DSA> structure and its components. The values are
|
|---|
| 28 | erased before the memory is returned to the system.
|
|---|
| 29 | If B<dsa> is NULL nothing is done.
|
|---|
| 30 |
|
|---|
| 31 | =head1 RETURN VALUES
|
|---|
| 32 |
|
|---|
| 33 | If the allocation fails, DSA_new() returns B<NULL> and sets an error
|
|---|
| 34 | code that can be obtained by
|
|---|
| 35 | L<ERR_get_error(3)>. Otherwise it returns a pointer
|
|---|
| 36 | to the newly allocated structure.
|
|---|
| 37 |
|
|---|
| 38 | DSA_free() returns no value.
|
|---|
