bitrary length. Such a parameter can be obtained using any of the functions EVP_PKEY_get_int_param(), EVP_PKEY_get_size_t_param() or EVP_PKEY_get_bn_param(). Attempting to obtain an integer value that does not fit into a native C <b>int</b> type will cause EVP_PKEY_get_int_param() to fail. Similarly attempting to obtain an integer value that is negative or does not fit into a native C <b>size_t</b> type using EVP_PKEY_get_size_t_param() will also fail.</p>
