PowerShell - SMTP Send

So I have a encrypted string stored in a text file that I can call again and again, this is the password for my SMTP Smart Host. This is created via:

Read-Host "Enter the Password:" -AsSecureString | ConvertFrom-SecureString | Out-File C:\EncPW.bin

I now need to somehow pass this along with a $username to a -Credential parameter for a Send-MailMessage function. I assume I need to get this into a PSCredential format. But I'm stuck !

$password = cat C:\encPW.bin |  ConvertTo-SecureString
$password

$cred = New-Object -typename System.Management.Automation.PSCredential -argumentlist      $username,$password

As of now I have this, but it $password when I print it outputs System.Security.SecureString and I get an error:

net_io_connectionclosed

When it tries to SMTP send.

Cheers

CALL to SMTP Send:

Send-MailMessage -from "[email protected]" -To "[email protected]" -Subject "Daily Report" -Body "Open Attachment for Report" -smtpServer 85.119.248.54 -Attachments "C:\WSB_Reports\DailyReport.txt" -Credential $cred

The approach you're taking appears correct assuming your username and password are correct. Is your username prefixed with the domain e.g. domain\username? I second the suggestion to try the command with a manually supplied credential via Get-Credential e.g.:

$cred = Get-Credential

If you need to verify the password coming back from the secure string is correct, you can display it like so:

$bstr = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($password)
$str =  [System.Runtime.InteropServices.Marshal]::PtrToStringBSTR($bstr)
[System.Runtime.InteropServices.Marshal]::ZeroFreeBSTR($bstr)
$str
