Example 3: Compute the hash value of a stream For this example, we are usingSystem.Net.WebClientto download a package from thePowerShell release page. The release page also documents the SHA256 hash of each pac
Open PowerShelland type the command above to test it. It calculates the SHA256 hash value for the given file and produces the output as follows. To calculate the hash value other than SHA256, use the switch -Algorithm. For example, to get the MD5 hash value, execute the following command...

良心啊,这个语言竟然是面向对象的 与面向过程相比,面向对象更方便更容易描述现实世界,也算赶上了时髦。 依托.NET 正所谓大树下面好乘凉,PowerShell绑上.NET这个大款了,借助.NET平台强大的类库,几乎让一切都成为可能。 强大的兼容性 完全兼容Windows平台上其它调用,如可执行文件(exe),批处理bat/cmd和VBscript等, 在...
