PowerShell 签名验证：使用 Get-AuthenticodeSignature 检查脚本签名状态
在 PowerShell 中，脚本签名是一种安全机制，用于确保脚本的来源可靠，防止恶意代码的执行。通过使用签名验证，用户可以确保他们运行的脚本是由可信的作者创建的。本文将围绕 PowerShell 的 `Get-AuthenticodeSignature` 命令展开，详细介绍如何使用该命令来检查脚本签名状态。
PowerShell 脚本签名是 PowerShell 安全策略的重要组成部分。它允许管理员和开发者为脚本添加数字签名，从而确保脚本的安全性。`Get-AuthenticodeSignature` 是 PowerShell 中用于检查脚本签名的命令之一。
Get-AuthenticodeSignature 命令概述
`Get-AuthenticodeSignature` 是一个用于获取和显示 Authenticode 签名的 PowerShell 命令。它可以从文件、URL 或其他来源检索签名信息，并显示签名者的详细信息、签名状态以及签名是否有效。
