Linux系統生成MD5、SHA、SHA256
md5sum file1.zip >> MD5.txt
sha1sum file1.zip >> SHA1.txt
sha256sum file1.zip >> SHA256.txt
校驗：
sha256sum -c <(grep file1.zip SHA256.txt)
windows系統生成MD5、SHA、SHA256
certutil -hashfile file1.zip MD5 >> MD5.txt
certutil -hashfile file1.zip SHA1 >>SHA1.txt
certutil -hashfile file1.zip SHA256 >> SHA256.txt
