Legend登陆验证说明
客户端 在各种闲置状态 发送
执行QueryDynCode
刚登陆场景就发送CM_QUERYDYNCODE
并加密
cnsIntro 登陆场景
dMsg := MakeDefaultMsg(CM_QUERYDYNCODE, 0, 0, 0, 0);
DCP_mars.InitStr(('sWebSite'));//加密密码
S := DCP_mars.DecryptString(g_pRcHeader.sWebSite);//sWebSite 用网站地址解密
DCP_mars.InitStr(S);//解密后的地址用作加密密码
S := DCP_mars.EncryptString(S);//加密
SendSocket(EncodeMessage(dMsg) + EncodeString(S)); //发送给登陆网关
Format('#1%s!', [{Code, } sendstr])
登陆网关解密 //DecodeBuf misc单元 其实和edcode单元的一样
nDeCodeLen := DecodeBuf(Addr, Len, nABuf);
解密分析后 再加密2次
Randomize();
nRand := Random(High(Word));//得到一个随机数
g_DCP_mars.InitStr(IntToStr(nRand));//把这个随机数作为加密的Key
g_DCP_mars.Reset;
szKey1 := EncodeString(g_DCP_mars.EncryptString(g_pszDecodeKey^));
g_pszDecodeKey就是网址作为加密密匙 //配置工具写入的
m_wRandKey := Random(High(Word));//再次取得一个随机数
Cmd.ident := SM_QUERYDYNCODE;
Cmd.Recog := g_pLTCrc^;//logintool CRC 长度
Cmd.param := nRand;//这是用于加密和解密的Key,但是需要转成String
Cmd.tag := m_wRandKey;
Cmd.Series := Length(szKey1);
EncodeBuf(Integer(@Cmd), SizeOf(TCmdPack), Integer(@pszBuf[0]));//把Cmd加密,保存到pszBuf中
EncodeBuf(Integer(@g_pszEndeBuffer[0]), g_nEndeBufLen, nBBuf);
szSend := '#' + StrPas(@pszBuf[0]) + szKey1 + StrPas(PChar(nBBuf)) + '!';
返回客户端 m_tIOCPSender.SendData(m_pOverlapSend, @szSend[1], Length(szSend));
客户端全局消息处理函数处理
SM_QUERYDYNCODE
g_bLoginKey^ := False;
Str := Copy(body, 1, msg.series);
Str := DecodeString(Str);
DCP_mars.InitStr(IntToStr(msg.param));
Str := DCP_mars.DecryptString(Str);
DCP_mars.InitStr('');
Str := DCP_mars.DecryptString(Str);
DCP_mars.InitStr(('sWebSite'));//解密密码
Str2 := DCP_mars.DecryptString(g_pRcHeader.sWebSite);
if CompareText(Str, Str2) = 0 then begin
g_bLoginKey^ := True;
g_pkeywords := NewStr('');
g_pkeywords^ := IntToHex(msg.tag, 8);
rdstr := Copy(body, msg.series + 1, Length(body) - msg.series);
edBuf := FEndeBuffer;
FillChar(edBuf^, 16 * 1024, #0);
len := DecodeBuf(Integer(@rdstr[1]), Length(rdstr), Integer(edBuf));
nFuncPos := Integer(@FEndeBuffer);
//asm pushad end;
ptrGetFunc := LPGETDYNCODE(nFuncPos);
cnsSelChr, cnsReSelChr 选择人物场景
dMsg := MakeDefaultMsg(CM_QUERYSELCHARCODE, 0, 0, 0, 0);
SendSocket(EncodeMessage(dMsg));//直接发送给selgate
