使用说明
1. 该工具只支持标准版XXTEA算法加解密，参考Cocos2d-x 3.12版本
　　2. 支持文件目录和单文件的加解密，注意加解密的输入和输出路径
　　3. 工具会自动判定文件签名是否符合条件，不符合条件的归为加解密失败
　　4. 若加解密失败可能原因有格式不对和对文件操作失败引起
　　5. 解密只识别文件头是否符合，若解密后为乱码则非标准算法或密钥引起。
　　6. 输出路径若存在同名文件则会直接覆盖掉。
　　7. 请不要强制关闭软件以免引起错误，具体加密完成请查看输出日志。(Instructions
1. This tool only supports standard version XXTEA encryption and decryption, refer to Cocos 2d-x 3.12 version.

2. Support the encryption and decryption of file directory and single file, pay attention to the input and output paths of encryption and decryption.

3. The tool will automatically determine whether the signature of the document meets the requirements, and the failure of encryption and decryption will be attributed to the failure of the qualified signature.

4. If encryption and decryption fails, there may be format errors and file operation failures.

5. Decrypting only identifies whether the header of the file is in conformity with the standard algorithm or key if the decryption is scrambled.

6. If the output path has the same name file, it will be overwritten directly.

7. Please do not force the shutdown of the software to avoid errors. Please check the output log when the encryption is completed.)
