DSA_NEW(3ossl) OpenSSL DSA_NEW(3ossl)
NAME
DSA_new, DSA_free - allocate and free DSA objects
SYNOPSIS
#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);
DESCRIPTION
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.
RETURN VALUES
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.

HISTORY
All of these functions were deprecated in OpenSSL 3.0.
