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

计算字符串、文件的MD5值，采用多线程，算法效率极高，UI简洁，易用。-Calculation of the string, the MD5 value of files, using multi-threaded, highly efficient algorithms, UI is simple and easy to use.
