AsyncFilwhen we need asynchronous behaviour or parallelism we create threads. The asynchronous file I/O APIs allows us to leverage the asynchronous behaviour without introducing threads. So we can issue ReadFileEx or WriteFileEx and perform other

支持多线程MD5文件完整性校验算法，只要给定文件路径就能计算他的校验码-Support multi-threaded MD5 file integrity check algorithm, as long as the given file path, he will be able to calculate the parity-check codes

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 beg
