Powershell - Secure String for Passwords and SFTP

I am trying to implement a way to use a stored secure string so that my SFTP password is not visiable in the script. For example, I'd like to generate a variable $password that could be used instead. I found the following examples online but I can't get them to work unfortunately. I've done something similar in the past but can find my notes or links to the website that explained how to complete the task.

read-host -assecurestring | convertfrom-securestring | out-file C:\securestring.txt 
$pass = cat C:\securestring.txt | convertto-securestring
$mycred = new-object -typename System.Management.Automation.PSCredential -argumentlist "test",$pass

Here is my script. Here is a link to the snapin if anyone is interested. http://www.k-tools.nl/index.php/sftp-in-powershell/

#Add the SFTP snap-in
Add-PSSnapin KTools.PowerShell.SFTP

#Define some variables
$sftpHost = "ftp.domain.com"
$userName = "user"
$userPassword = "password"

$localFile = "C:\bin\emp1.xlsx"

#Open the SFTP connection
$sftp = Open-SFTPServer -serverAddress $sftpHost -userName $userName -userPassword $userPassword

#Upload the local file to the root folder on the SFTP server
$sftp.Put($localFile)

#Close the SFTP connection
$sftp.Close()

Again, thanks for everyones help!

UPDATE

I tried this:

$pass = cat c:\bin\ftpcreds.txt | convertto-securestring
$mycred = new-object -typename System.Management.Automation.PSCredential -argumentlist "usertest1",$pass
$sftpHost = "ftp.domain.com"
$userName = $mycred.username
$userPassword = $mycred.password
$sftp = Open-SFTPServer -serverAddress $sftpHost -userName $userName -userPassword $userPassword
$sftp.Put($localFile)
$sftp.Close()

And get this error:

Method invocation failed because [Tamir.SharpSsh.jsch.JSchException] doesn't contain a method named 'Put'.
At C:\bin\SFTP Upload Samples.ps1:21 char:1
+ $sftp.Put($localFile)

    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

Method invocation failed because [Tamir.SharpSsh.jsch.JSchException] doesn't contain a method named 'Close'.

+ $sftp.Close()
+ ~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [], RuntimeException

Any suggestions?

Thanks!

If your SFTP is wanting to use a decrypted version of your secured password then you'll want to extract it from your $mycred by:

$userpassword = $mycred.getnetworkcredential().password.tostring()
