crc32

说明：  crc32磁盘文件完整性检验 计算的CRC32的起始位置是PE文件头开始处,结束位置在整个文件的尾部. 当然,没有软件会是绝对安全的,所以可以把CRC32值进行一些加密处理或者修改计算CRC32的范围.总之是可以先做点改变再写入判断. 附件带有计算写入CRC32的工具源码及一个测试的程序源码和一个做好的程序.
(crc32 disk file integrity verification start position calculation of CRC32 is the beginning of PE header, the end of the rear position in the entire document. Of course, no software is absolutely safe, so the CRC32 value can be encrypted or modify the calculation of some CRC32 range. All in all, you can do first for a change and then write the check. Annex write CRC32 calculation tool with source code and a test program source code and a good program.)
