+    \brief This function generates a new ecc_key and stores it in key.
+
+    \return 0 Returned on success.
+    \return ECC_BAD_ARG_E Returned if rng or key evaluate to NULL
+    \return BAD_FUNC_ARG Returned if the specified key size is not in the
+    correct range of supported keys
+    \return MEMORY_E Returned if there is an error allocating memory while
+    computing the ecc key
+    \return MP_INIT_E may be returned if there is an error while computing
+    the ecc key
+    \return MP_READ_E may be returned if there is an error while computing
+    the ecc key
+    \return MP_CMP_E may be returned if there is an error while computing the

+    \return MP_INVMOD_E may be returned if there is an error while computing
+    the ecc key
+    \return MP_EXPTMOD_E may be returned if there is an error while computing

+    \return MP_MOD_E may be returned if there is an error while computing the
