Powershell Script How To Run

Powershell Script How To Run – There is inevitably some risk from a collection of PowerShell scripts stored on your network. For example, an attacker could inspect one of your scripts to gain insight into your organization’s IT infrastructure. Likewise, an attacker (or a well-intentioned IT employee in your company) can modify a script that causes common problems.

One way to reduce these risks is to create encrypted PowerShell scripts. An encrypted script requires much more effort to read or modify than a plain text script.

The first step in creating an encrypted PowerShell script is to write a plain text version of the script. Once the script is ready, test it thoroughly and rename the script file to have a .TXT file extension.

In Figure 1, I created a simple Hello World script that was saved as a text file called MyCode.txt.

You need to read your text file into PowerShell, encrypt the contents of the file, and write that encrypted contents to a file. Here are some commands to read, decrypt and extract the code contained in a text file:

In this piece of code, we’ll create a variable named $Code that contains the unencrypted content of the text file. Next, we convert the script file to a secure string and store its contents in a variable called $CodeSecureString. At this point, we treat the text file as a clear password. The third line of code converts the secure string data into an encrypted value. Finally, in the last line of code, we write the encrypted data to a text file called Encrypted.txt.

Figure 2 shows these steps. In the image, I’ve added extra lines that output the contents of the $Code, $CodeSecureString, and $Encrypted variables so you can clearly see what these variables are used for. I also extracted the encrypted.txt file to see its contents.

Once we have encrypted the original script, we have completed the first half of the process. Unfortunately, we can’t just drop code into PowerShell and expect it to work. In addition to pasting the encrypted code into the script, we need to add a few commands that tell PowerShell how to decrypt the code.

The first instruction writes the encoded code to a variable named $Instructions. Next, we create a variable called $Decrypt, convert the encrypted code to a secure string, and write the result to the $Decrypt variable. From there, we call .NET for the final encryption. The encrypted code is written to a variable named $Code. We can then use the Invoke-Expression cmdlet to execute the code.

In Figure 3, I entered the above instructions manually. In doing this, I also extracted the contents of the $Decrypt and $Code variables to see how the encryption process works.

The key is to embed all of the code in the example above into a PowerShell script and use it as is. Encryption makes it almost impossible to tell why the script was created without running it. It also prevents anyone from changing the script, as an unauthorized change could corrupt the encrypted string.

First, the example I used above is for a very simple situation. If you are trying to code a longer, more complex script, you may need to create a loop to read and execute the coded instruction once – instead of trying to -do everything with a single Invoke-Expression statement.

Second, you can use the same method to encrypt secure password files generated by PowerShell (using Get-Credential). Therefore, since password files can be opened, we must remember that they should be stored in a safe place.
