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
OPENSSL_API_COMPAT with a suitable version
value, see
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
EVP_PKEY_new(3) and
EVP_PKEY_free(3).
DSA_new() allocates and initializes a
DSA structure. It is
equivalent to calling DSA_new_method(NULL).
DSA_free() frees the
DSA structure and its components. The values
are erased before the memory is returned to the system. If
dsa is NULL
nothing is done.
If the allocation fails,
DSA_new() returns
NULL and sets an error
code that can be obtained by
ERR_get_error(3). Otherwise it returns a
pointer to the newly allocated structure.
DSA_free() returns no value.
EVP_PKEY_new(3),
EVP_PKEY_free(3),
DSA_new(3),
ERR_get_error(3),
DSA_generate_parameters(3),
DSA_generate_key(3)
All of these functions were deprecated in OpenSSL 3.0.
