hi,完全copy官网的代码测试SM9功能，在keygen的时候返回NULL,希望得到帮助，谢谢！

<<<<<<<<<<<<<<< int testSM9() { int err = 1; int curve_id = NID_sm2p256v1; //FIXME //int curve_id = NID_sm2sign; char id = "guanzhi1980@gmail.com"; char in = "message to be signed or encrypted"; SM9PublicParameters mpk = NULL; SM9MasterSecret msk = NULL; SM9PrivateKey sk = NULL; unsigned char dgst[32] = { 0x01, 0x00 }; unsigned char c = NULL; unsigned char m = NULL; unsigned char sig = NULL; size_t clen, mlen, siglen;

/* setup */
if (!SM9_setup_by_pairing_name(curve_id, SM9_HID_SIGN, &mpk, &msk)) {
    goto end;
}

/* keygen */
if (!(sk = SM9_extract_private_key(mpk, msk, id, strlen(id)))) {
    goto end;
}

<<<<<<<<<<<<<<<<<<

出错的地方sm9_keygen.c文件中位置： <<<<<<<<<<<<<<<

/* EC_GROUP */
if (!(group = EC_GROUP_new_type1curve_ex(mpk->p,
    mpk->a, mpk->b, mpk->pointP1->data, mpk->pointP1->length,
    mpk->order, mpk->cofactor, bn_ctx))) {
    SM9err(SM9_F_SM9_EXTRACT_PRIVATE_KEY, SM9_R_INVALID_TYPE1CURVE);
    goto end;
}
