=========================================================================== | |
.DESCRIPTION | |
This function can be used to create both an AES encryption key file and password file that can be used | |
to pass secure passwords through PowerShell scripts | |
.EXAMPLE | |
Create-AESPasswordFile | |
============================================================================================================================= | |
Please enter the full path and file name for the AES Key (e.g. C:\AESKey.txt): C:\Temp\AES_OneDrive.txt | |
Please enter the password to encrypt: ******************** | |
Please enter the full path and file name for the Secure Password file (e.g. C:\AppSecurePwd.txt): c:\temp\Secure_OneDrive.txt | |
----------------------------------------------------------------------------------------------------------------------------- | |
.EXAMPLE | |
To use the saved files add the below code to your script | |
$UserName = "YOUR USERNAME HERE} | |
$SecurePwdFilePath = {PATH TO YOUR PASSWORD FILE HERE} | |
$AESKeyFilePath = {PATH TO YOUR AESKEY FILE HERE} | |
$AESKey = Get-Content $AESKeyFilePath | |
$pwdTxt = Get-Content $SecurePwdFilePath | |
$securePwd = $pwdTxt | ConvertTo-SecureString -Key $AESKey | |
$credObject = New-Object System.Management.Automation.PSCredential -ArgumentList $username, $securePwd | |
You can now pass the $CredObject with the -Credential switch e.g. Connect-MsolService -Credential $CredObject | |
#> | |
function Create-AESPasswordFile { | |
# Create a 32 bit random key to be used by the AES Key | |
$AESKey = New-Object Byte[] 32 | |
[Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($AESKey) | |
#Collect the location to store the AES Key file | |
$AESKeyFilePath = Read-Host -Prompt "Please enter the full path and file name for the AES Key (e.g. C:\AESKey.txt)" | |
Set-Content $AESKeyFilePath $AESKey #It will over-write existing file data if already exists | |
#Collect the password to encrypt. It uses the -AsSecureString to hide the text then converts it back text and encrypts using the AES Key | |
$InputPwd = Read-Host -Prompt "Please enter the password to encrypt" -AsSecureString | |
$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($InputPwd) | |
$PlainTxtPsswd = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($bstr) | |
$secureStringPwd = $PlainTxtPsswd | ConvertTo-SecureString -AsPlainText -Force | |
#Export Secure content to password file | |
$SecurePwdFile = Read-Host -Prompt "Please enter the full path and file name for the Secure Password file (e.g. C:\AppSecurePwd.txt)" | |
$password = $secureStringPwd | ConvertFrom-SecureString -Key $AESKey | |
Add-Content $SecurePwdFile $password | |
