=head1 NAME
DSA_new, DSA_free - allocate and free DSA objects
#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)>:
DSA* DSA_new(void);
void DSA_free(DSA *dsa);
All of the functions described on this page are deprecated.
Applications should instead use L<EVP_PKEY_new(3)> and L<EVP_PKEY_free(3)>.
DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
calling DSA_new_method(NULL).
DSA_free() frees the B<DSA> structure and its components. The values are
erased before the memory is returned to the system.
If B<dsa> is NULL nothing is done.
If the allocation fails, DSA_new() returns B<NULL> and sets an error
code that can be obtained by
L<ERR_get_error(3)>. Otherwise it returns a pointer
to the newly allocated structure.
DSA_free() returns no value.
