PowerShell中实现混淆密码示例

适用于PowerShell 3.0或者更高版本，
尽管我们并不推荐将密码硬编码在脚本文件中，但是仍旧有一些场景非如此不可。与将密码以一种纯文本的方式硬编码相比，我们还可以稍微花点心思，把密码混淆一下。虽然混淆密码是一种非常低级的保护方式，但是对于不懂PowerShell的人来讲，还是比较神秘的。

接下来的脚本会向用户询问用户名和密码，然后删除通过混淆脚本进行处理，产生用户凭据对象。

当你运行了下面的脚本以后，用户凭据已经被保存在$cred。接下来你几乎可以在任何带有–Credential参数的命令中使用它了。
$cred = Get-Credential -Message 'Enter Domain\Username and Password'
$pwd = $cred.Password
$user = $cred.UserName
$key = 1..32 | ForEach-Object { Get-Random -Maximum 256 }
$pwdencrypted = $pwd | ConvertFrom-SecureString -Key $key
 
$private:ofs = ' '
 
$generatedScript = @()
$generatedScript += '$password = ''{0}''' -f $pwdencrypted
$generatedScript += '$key = ''{0}''' -f "$key "
 
$generatedScript += '$passwordSecure = ConvertTo-SecureString -String $password -Key ([Byte[]]$key.Split('' ''))'
$generatedScript += '$cred = New-Object system.Management.Automation.PSCredential(''{0}'', $passwordSecure)' -f $user
$generatedScript += '$cred'
 
$file = $psise.CurrentPowerShellTab.Files.Add()
$file.Editor.Text = $generatedScript | Out-String
$file.Editor.SetCaretPosition(1,1)
</div>

产生的密码可能像这样：

$password = '76492d1116743f0423413b16050a5345MgB8AHMAUQA3AFAAVwB0AGkAUQBUAC8AdwBqADYAUABVAFYAUwB4AEYAYgB4AFEAPQA9AHwAZgA0ADgAOQA4AGYANwA0AGEAMAA0ADUANwA5ADkAMwA5ADkAMwA1ADUANQA0AGYANwA5AGQANwBkAGYAOQBmAGEAYQA3ADMAYgBkADIAOQA3AGMAYQBmADUAMgA3ADEANwA3AGEAYgBmADAAYgA1AGYAYwAyADYAYgAzADkAOAA='
$key = '187 98 34 82 148 52 13 86 246 2 130 197 217 97 147 98 75 197 149 246 74 35 27 7 211 15 131 93 182 231 171 3'
$passwordSecure = ConvertTo-SecureString -String $password -Key ([Byte[]]$key.Split(' '))
$cred = New-Object system.Management.Automation.PSCredential('mickey\mouse', $passwordSecure)
$cred
</div>
