For license with 239bit SIGN2, I see two groups of private keys as below after compiler SDK. Then whether this ecc patch still work? Or should add the 2nd corresponding pubkey into the patcher also?

static unsigned char lm_prikey[2][3][40] = {{{0x0, 0xb2, 0x45, 0x2c, 0xbc, 0x7e, 0x72, 0xc1, 0x3a, 0x39, 0x5e, 0x67, 0x25, 0xce, 0xd9},
{0x2, 0x1c, 0x8f, 0xa2, 0xe4, 0xb6, 0x4f, 0x7a, 0x2c, 0xd2, 0x6, 0x81, 0xb5, 0xd8, 0xf9, 0xf1, 0x81, 0x6, 0x4a, 0x8e, 0x17},
{0x3, 0xa0, 0x58, 0x89, 0xd2, 0x30, 0x22, 0xd8, 0xca, 0x5e, 0xac, 0x59, 0x33, 0xb3, 0x69, 0xdc, 0x30, 0x9b, 0xb6, 0x8d, 0x24, 0x56, 0x60, 0x23, 0xf0, 0x8c, 0x11, 0xb8, 0xc2, 0xba}}
