Powershell加密文本信息 1


适用于Powershell3.0及以后版本。
假设你需要给文件加密,下面教你如何给自己的文件加密:

$Path = "$env:temp\secret.txt"
$Secret = 'Hello World!'
$Passphrase = 'Some secret key'

$key = [Byte[]]($Passphrase.PadRight(24).Substring(0,24).ToCharArray())

$Secret |
  ConvertTo-SecureString -AsPlainText -Force | 
  ConvertFrom-SecureString -Key $key | 
  Out-File -FilePath $Path

notepad $Path

当你需要解密出里面的内容,这时就需要最初的密码:

$Passphrase = Read-Host 'Enter the secret pass phrase'

$Path = "$env:temp\secret.txt"

$key = [Byte[]]($Passphrase.PadRight(24).Substring(0,24).ToCharArray())

try
{
  $decryptedTextSecureString = Get-Content -Path $Path -Raw |
  ConvertTo-SecureString -Key $key -ErrorAction Stop

  $cred = New-Object -TypeName System.Management.Automation.PSCredential('dummy', $decryptedTextSecureString)
  $decryptedText = $cred.GetNetworkCredential().Password
}
catch
{
  $decryptedText = '(wrong key)'
}
"The decrypted secret text: $decryptedText"

一条评论 “Powershell加密文本信息

  • 陈47

    想请教你一个问题:怎么用powershell将连接数据库的密码等相关信息进行加密?
    这是我脚本中的一部分代码:
    [void][System.Reflection.Assembly]::LoadWithPartialName(“MySql.Data”)
    $connectionStr = “Server=10.0.0.1;Uid=user;Pwd=123456;database=my_test;”
    $querysql = “SELECT ServerOSSFilePath FROM test WHERE ID = ‘ser’;”
    $connection = New-Object MySql.Data.MySqlClient.MySqlConnection
    $connection.ConnectionString = $connectionStr
    $connection.Open()
    怎么将$connectionStr里面的字符串进行加密啊???
