I hope this has been helpful in showing that with a small amount of effort you can get away from storing passwords in plain text in your Powershell scripts. After that we can use that credential object willy nilly, example on line 23. The simplest way to create a PSCredential object is by using the following command: Credential Get-Credential This command will generate the following prompt where you can enter your credentials: As seen in below output you now have a PSCredential object stored in the Credential variable. We don’t specify any parameters with the ConvertTo-SecureString method because we want it to use the Windows account running the script for decryption, exactly like we did with the ConvertFrom-SecureString for the encryption. Note the secret sauce that imports the password on lines 6 and 7. Use a plaintext representation of SecureString. $SMTPClient.Send( $EmailFrom, $EmailTo, $Subject, $Body) Create PSCredentials Assuming that you have password in SecureString form in SecurePassword variable: Extract password from PSCredentials The password can be easily obtained from PSCredential object using GetNetworkCredential method: 001 PlainPassword Credentials.GetNetworkCredential(). Notice below that the password shows as, which indicates the password encrypt worked well. $SMTPClient.EnableSsl = $true $SMTPClient.Credentials = $credential Now that you know the secret’s name run the command below to retrieve the secret’s value. $EmailFrom = $EmailTo = $Subject = "I did some stuff!" $Body = "This is a notification from Powershell." $SMTPServer = "" $SMTPClient = New-Object ( $SmtpServer, 587) $emailusername = "myemail" $encrypted = Get-Content c:scriptsencrypted_password.txt | ConvertTo-SecureString $credential = New-Object ( $emailusername, $encrypted) User: > Administrator Password for user Administrator: PS /root> PasswordPassword : The term Password is not recognized as the name > of a cmdlet, function, script file, or operable program. Here is a simplified snippet of code using the encrypted password: PS /root> cred Get-Credential > Windows PowerShell credential request Enter your credentials. Step 2: Use the encrypted password file in your automation scripts. In a production environment, I would recommend a service account used solely for creating and running the encryption and automation scripts. (Get-Secret -Name Secret1).GetNetworkCredential() Select-Object And you have now successfully retrieved the password. More importantly, I didn’t see an obvious way of making the the key secure and accessible. Finally, run the below command to call the GetNetworkCredential () method on the PSCredential to view the password in plain text. Why wouldn’t I specify a key? Laziness mostly, and I like methods that integrate with Windows authentication. For more information check out this long boring article. So, you can’t decrypt with the same account from another machine. Note that it’s also specific to the machine where you encrypted it. The returned password should be the same password you provided to the PSCredential constructor.xample Code: credential.GetNetworkCredential().Password To see. Additionally, by using a PowerShell script. Basically, that means using your Windows profile as the key. The encryption process uses a secure algorithm to convert plaintext into ciphertext, making it unreadable. If you don’t specify a Key or SecureKey parameter, the default is to use the Windows Data Protection API. From Plain Text String From Host Input Get Encrypted String From SecureString Get Plaintext String from SecureString Generate Random. \Clowns. They “key” to this…Wah wah…is your Windows account. To get the password back out in to a usable credential variable like the article, you'd do this. This will create a text file in the specified location with a hash of your password. Username isn’t important since we are just storing the password, but go ahead and enter it anyway. Run this script in Powershell, remember to set the execution policy appropriately, and Windows will prompt you for a username and password. Master-PowerShell by Dr.$credential = Get-Credential $credential.Password | ConvertFrom-SecureString | Set-Content c:scriptsencrypted_password1.txt.PowerShell can store passwords in 3 different forms: String - Plain text strings are stored in memory as unsecure plain text and most cmdlets will not accept passwords in this form. If you omit PSCredential, you will be prompted for a user name and a password. NET, POSH is a full-featured task automation framework for distributed Microsoft platforms and solutions. When you enter the command, you will be prompted for a password. Windows PowerShell (POSH) is a command-line shell and associated scripting language created by Microsoft.
