How to secure passwords with PowerShell – Guide
Do you have loops or scripts that expect you to enter a secret key? Do you need to store these plaintext passwords in your content against the wishes of your security officer? PowerShell provides a method to store a secret key or inform the client about the data. You can then use this data to make what is known as a PSCredential. Most PowerShell requests that help distant associations with servers (WMI, CIM, Invoke-Command, and so on) provide a method to pass a certification.
While some only require the secret key, others require the full item to validate a client. This item in PowerShell can be done in several ways depending on your needs. Supervisors often need to store passwords directly in a variety of PowerShell scripts in computerization situations.
As you are probably aware, this is incredibly unreliable in a crafting climate in light of the fact that other server clients or presidents can see the secret key in plain text. Therefore, it is smarter to wrap a more secure strategy to wrap passwords in PowerShell scripts or to scramble passwords when intelligent information is unimaginable.
How to secure passwords with PowerShell
PSCredential
The complete type is the “System.Management.Automation.PSCredential” object. Commands that use a “-Credential” parameter usually require this type to be passed. You have a few different ways to do this based on your needs. Each method usually lines up to two different scenarios: interactive or automated. The PSCredential object requires two arguments:
The username is pretty obvious, but the password is not just a string value. You can’t just take a string and declare it as SecureString. To create a SecureString first, you must specify a password. Depending on how you do it, it can be a security risk in most environments because you are passing (or storing) your password in plain text. When working with passwords in PowerShell, it’s best to obfuscate your password to protect it from prying eyes. PowerShell provides a few different options to hide your password. I will explain them below with some examples.
a small caveat
When working with PSCredential objects, you will notice that there is a way to read the password as plain text. This object contains properties for a specific method that returns the password as plain text. The method is called: GetNetworkCredential(). This method has four properties: Domain, Password, SecurePassword and UserName. These properties are present because there may be times when you are working with 3rd party commands or executables and need to pass the password in clear text. You can use this property without having to display it as plain text in your script.
This means that you should be aware that while the methods shown are useful for meeting certain security requirements, you should also be aware of the risk that these variables remain in memory after the script completes. It’s better to get in the habit of cleaning up at the final. Whenever you use the methods listed below, they must be local to the specific function that uses them.
read host
Interactive commands mean that you will ask the user to enter some information, such as a password. Read-Host is useful for prompting for the password on the command line, especially if you don’t need the username either. To get the SecureString object just use the “-AsSecureString” parameter. This will show the password with asterisks as the user types it and return a SecureString object.
get credential
Using this command will give the user a pop-upup window they are probably most familiar with, to enter their username and password. The advantage you have with this command is after the user clicks the “Ok” button button it will return a PSCredential object. This can save you a few more lines of code compared to the “Read-Host” command, which would still require you to create the PSCredential object. This command is a favorite for one-line commands where you need to quickly create a PSCredential object for a given command in PowerShell.
After clicking OK, we can see that a PSCredential object is returned. If you want to use this in one line like with “Get-WmiObject”, you can just do this:
