powershell保护明文密码

winrm脚本能运行了，就想着明文密码怎么也隐藏一下，网上搜了一圈，还是sparkdev的简单明了：

试着走一下，txt方式有效，高级的txt+key却报错“ConvertTo-SecureString : 输入数据不是完整的块”，一时也不知怎么解决，只得记下日后反刍。

$Password = 'pwd'
$pass = ConvertTo-SecureString -AsPlainText $Password -Force
ConvertFrom-SecureString $SecurePwd | Out-File "路径\pwd.txt"
$pass=get-content "路径\pwd.txt" | convertto-securestring

报错的txt+key步骤：

$pwd="路径\pwd.txt"
$keyfile="路径\pwd.key"
$key = new-object byte[] 32
[Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($key)
$key | out-file $keyfile
$key = Get-Content $keyfile
$Cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $Username,(Get-Content $pwd | ConvertTo-SecureString -Key $key)
