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.
