cocos2dx 3.5 资源文件加密

Delphi 加密工具 使用CnPack

fstream:=TMemoryStream.Create();

DestStream:=TMemoryStream.Create;

fstream.LoadFromFile(edt1.Text);

fcnstream:=TCnXorStream.Create(fstream,'123456789',false);

GetMem(buffer, fstream.Size);

fcnstream.Read(buffer^,fstream.Size);

DestStream.write(buffer^,fstream.size);

str:=StringReplace(edt1.Text,'.png','.cee',[rfReplaceAll]);

DestStream.SaveToFile(str);

ShowMessage(str);

更改代码 CCImage.cpp

if (!data.isNull())

{

//图像加密

auto bin = data.getBytes(); //unsigned char*

auto size = data.getSize();

unsigned char *buffer = (unsigned char*)malloc(sizeof(unsigned char)* (size ));

buffer = data.getBytes();

std::string r = ".cee";

const char *show;

show = strstr(_filePath.c_str(), r.c_str());//返回指向第一次出现r位置的指针，如果没找到则返回NULL。

if (show != NULL)

{

if (PASSWORD)

{

auto *cur = reinterpret_cast<char *>(bin);

int i;

//string pw = PASSWORD;

std::stringstream strValue;

strValue << PASSWORD;

char* ps = new char[50];

strValue >> ps;;

int l = strlen(ps);

for (i = 0; i < size; i++)

{

//*cur^= ps[(i % l)+1 ];

// cur++;

cur[i] ^= ps[(i % l)];

}

//for i : = 0 to Count - 1 do

//PByteArray(@Buffer) ^ [i] : = PByteArray(@Buffer) ^ [i] xor

// Byte(FXorStr[(p + i) mod l + 1]);

}

}
