![]() ![]() Then open the file in Hex Editor of Notepad ++ and convert it to hexadecimal notation. Opened with TexturePacker with excitement, but reported failure. Then, copy the generated ccz file back to the local machine, adb pull, "Permission Denied "? Chmod. Create a ccz file and write the file header and source. Sig is "CCZ !", Compress_type is 0, version is 2, reserved is 0, len is * destLen. Source does not contain the file header, so you need to fill in the file header yourself. After all, all images must be delivered to opengl for rendering. Apart from hijacking uncompress, you can also hijack the opengl interface. In this case, I only need to hijack the uncompress interface to crack the resource. The source and destLen parameters are used here. Int uncompress(Bytef *dest, uLongf *destLen, const Bytef *source, uLong sourceLen) Originally, ccz is also a zip compression format. Next, call the libz decompression interface: If it is encrypted, it will be decrypted. This interface will read the binary data of the ccz file, and then determine whether the ccz file is legal based on the first four bytes ("CCZ !") Or whether to encrypt the ccz file ("CCZp"). I will turn to the implementation of ccInflateCCZFile. However, the symbolic names obtained from soinfo-> symtab are always garbled. I want to hijack the User-Defined interface for key setting: ccSetPvrEncryptionKeyPart, so that you can get the password directly. Void ZipUtils: ccSetPvrEncryptionKeyPart (int index, unsigned int value) // set the key interface int ZipUtils: ccInflateCCZFile (const char * path, unsigned char ** out) // interface for loading ccz files Then, open the lib directory inside the torch package, found that the torch is the development of cocos2d-js v2.2, go to the cocos2d-x official download v2.2.5. ![]() If the message "Permission Denied" is displayed, mount/data and change the File Permission (chmod ). The following are some specific operations.įirst RootTo copy the injection process and hijacking database to the mobile phone, for example, the adb push command under the/data directory. The attack was successful, and I had a good idea of cracking. traverse the got table, find the interface address, and replace it with the self-written interface.Īfter the injection and hijacking are both OK, I tried to hijack printf and replace it with my own function. LibInject, the core system API is ptrace, there are also several APIs that operate the dynamic link library, such as dlopen, dlsym, dlclose, and dlerror. Further, it is found that some people have open-source injection libraries written by themselves. Google "linux + inject" can also be injected in linux. Can I intercept APIs through injection in linux? As long as the API can be hijacked, it can be cracked. I just remember that the general principle is to inject my own DLL into the target process, hijack some APIs, and replace them with my own implementations. I haven't done PC development in a few years, but I have forgotten the specific implementation. Only a few years ago, I used DLL injection and API Interception when I was reading Windows core programming. The engineer's job is to reduce labor and improve production efficiency.ĭynamic library injection and API InterceptionĪt the beginning, I had no idea at all, because I developed a game and never cracked it. Therefore, the best method is to study the encrypted resources used to crack the torch. Not to mention that it takes a lot of energy to do a heavy amount of physical work, this kind of thing will be "terrible", and when the formal art resources come, all the art shows also need to be adjusted by the program, this is a huge workload. However, the ratio of a sketch to the source image is: the size and specification are incorrect, the quality is poor, and the elements are stacked together. ![]() The torch resource is encrypted and cannot be opened without a key.Īn artist can use a sketch or draw a sketch for the program. So I have been using v2.4.5 for a long time and have not upgraded it. I recently developed Unity, and only needed the most basic gallery function of TP. ![]() Just a little bit, I know that TP provides the encryption function. I decompress the tornado apk and found that the command line of TexturePacker could not convert its pvr. In order to develop programs in parallel with art production, we plan to use the torch resources for the moment. UI and interaction are intended to learn from the currently popular "Legend of the Holy Fire". Recently, we want to launch a new project. Crack TexturePacker's encrypted resources and texturepacker's encryption ![]()
