DSA_new(3)                          OpenSSL                         DSA_new(3)




NAME

       DSA_new, DSA_free - allocate and free DSA objects


LIBRARY

       libcrypto, -lcrypto


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.
