Your structure seems good. uint64 Unk; is GuildID, which is now composed by a lowguid and a highguid.

// NOTE: ATM the socket is singlethread, have this in mind ... uint8 digest[20]; uint32 clientSeed, id, security, addonsize; uint16 ClientBuild; //uint8 expansion = 0; LocaleConstant locale; std::string account; SHA1Hash sha1; BigNumber v, s, g, N, K; WorldPacket packet; if (sWorld.IsClosed()) { packet.Initialize(SMSG_AUTH_RESPONSE, 1); packet << uint8(AUTH_REJECT); SendPacket (packet); sLog.outError ("WorldSocket::HandleAuthSession: World closed, denying client (%s).", m_Session->GetRemoteAddress().c_str()); return -1; } // Read the content of the packet uint8 unk15; uint64 unk4; uint32 unk6; uint32 unk8; uint32 unk10; uint32 unk12; uint8 unk16; recvPacket >> unk15 >> digest[15]; recvPacket >> ClientBuild; recvPacket >> digest[5] >> digest[19]; recvPacket >> unk4; recvPacket >> digest[13] >> digest[10] >> digest[1]; recvPacket >> unk6; recvPacket >> digest[12] >> digest[4] >> digest[18] >> digest[8]; recvPacket >> unk8; recvPacket >> digest[11] >> digest[9] >> digest[2]; recvPacket >> unk10; recvPacket >> digest[6] >> digest[16]; recvPacket >> unk12; recvPacket >> clientSeed; recvPacket >> unk16 >> digest[7] >> digest[0] >> digest[3] >> digest[17] >> digest[14]; recvPacket >> account; //addon...

It's packet << uint32(0); packet << uint32(0); packet << uint32(m_Seed); packet << uint32(0); packet << uint8(1); packet << uint32(0); packet << uint32(0); packet << uint32(0); packet << uint32(0); packet << uint32(0); Yours is 8 Bytes key seed 4 Bytes Key uint8 ConnectionCount 20 Bytes key but it should be 16 byte key seed connectioncount 16byte key I know that it should be 16-seed-coonection-16. But it changed(in 13329, I think) yours does not work . With mine, I get a good digest, so... Thanks. EDIT: ChasterX, do you have a github account? Can I have the email associated, for the commit in my repo? EDIT2: I have 578 opcodeID. I'll share them toworrow.

It's packet << uint32(0); packet << uint32(0); packet << uint32(m_Seed); packet << uint32(0); packet << uint8(1); packet << uint32(0); packet << uint32(0); packet << uint32(0); packet << uint32(0); packet << uint32(0);
