DH_new(3)                           OpenSSL                          DH_new(3)




NAME

       DH_new, DH_free - allocate and free DH objects


SYNOPSIS

        #include <openssl/dh.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):

        DH* DH_new(void);

        void DH_free(DH *dh);


DESCRIPTION

       DH_new() allocates and initializes a DH structure.

       DH_free() frees the DH structure and its components. The values are
       erased before the memory is returned to the system.  If dh is NULL
       nothing is done.


RETURN VALUES

       If the allocation fails, DH_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.

       DH_free() returns no value.

       DH_generate_key(3), EVP_PKEY-DH(7)


HISTORY

       All of these functions were deprecated in OpenSSL 3.0.

       For replacement see EVP_PKEY-DH(7).
