Question

我正在尝试批量从securestring中提取密码。

这是在PS：

Read-Host "Enter Password" -AsSecureString |  ConvertFrom-SecureString | Out-File "C:\Temp\Password.txt"
$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString
$stringValue = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass));

它按预期工作。

我正在批量转换上面的代码：

powershell -Command "& {Read-Host "Enter Password" -AsSecureString |  ConvertFrom-SecureString | Out-File "C:\Temp\Password.txt"}" 
powershell -command "& {$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString; ^
$stringValue = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass))}"
FOR /F "usebackq delims=" %v IN (`stringValue`) DO set "d=%v"
echo %d%

我不确定是否有什么问题，我只能在 echo％d％上获得“ powershell.exe -encodedCommand $ encoded命令”，而不是明文密码。< / p>

在能够在cmd中使用它之前，您必须回显$stringValue。您可以使用转化结果的回应将作业替换为$stringValue，并将其嵌入到for＆＃34;循环＆＃34;。

修改

让我们写一些代码。

:: Write the password to File (unchanged) powershell -Command "& {Read-Host "Enter Password" -AsSecureString | ConvertFrom-SecureString | Out-File "C:\Temp\Password.txt"}" ::Read in the file, echo it out. (changed at the end) powershell -command "& {$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString; $stringValue = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass));echo $stringValue}"

上面代码中的最后一行以纯文本形式显示密码。现在，您只需将最后一行嵌入到for循环中，而不是只显示密码：

FOR /F "usebackq delims=" %v IN (`powershell -command "& {$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString; $stringValue = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass));echo $stringValue}"`) DO set "d=%v"

现在，echo会给我密码：

C:\Temp> FOR /F "usebackq delims=" %v IN (`powershell -command "& {$pass = Get-Content "C:\Temp\Password.txt" | ConvertTo-SecureString; $stringValue = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pass));echo $stringValue}"`) DO set "d=%v" C:\Temp> set "d=asdf" C:\Temp> echo %d% asdf C:\Temp>
