powershell - 输入带有掩码的密码

Question

我从其他一些帖子中整理了一个简单的示例:

[CmdletBinding(
    DefaultParameterSetName = 'Secret'
)]
Param (
    [Parameter(Mandatory=$True)]
    [string]$FileLocation,

    [Parameter(
        Mandatory = $True,
        ParameterSetName = 'Secret'
    )]
    [Security.SecureString]${Type your secret password},
    [Parameter(
        Mandatory = $True,
        ParameterSetName = 'Plain'
    )]
    [string]$Password
)

if ($Password) {
    $SecretPassword = $Password | ConvertTo-SecureString -AsPlainText -Force
} else {
    $SecretPassword = ${Type your secret password}
}

Write-Host $SecretPassword
$BSTR = `
    [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecretPassword)
    $PlainPassword = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
    Write-Host $PlainPassword

How can I use powershell's read-host function to accept a password for an external service?

运行脚本时，如何使输入的密码被屏蔽？

所以代替这个:

PS C:\temp> .\test.ps1 -FileLocation C:\Temp\file.csv  -Password secret

这个

PS C:\temp> .\test.ps1 -FileLocation C:\Temp\file.csv  -Password ******

Answer 1

首先，您的示例不会发生。建议您在脚本执行之前，希望他们从中执行脚本的任何shell都将其作为参数输入来屏蔽密码。没有发生。

现在，一种替代方法是不接受密码作为参数，而是每次都提示输入密码。在这种情况下，您可以将整个If($Password)语句减少为:

$SecretPassword = Read-Host 'Type your secret password' -AsSecureString
