Powershell script to invoke Tufin Path analysis API

There is an undocumented Tufin API, see the code below:

#Parameters must be declared at the start of the script.
Param(
    [Parameter(Mandatory=$true)][string]$usr,
    #[Parameter(Mandatory=$true)][string]$pwd,
    [Parameter(Mandatory=$true)][ipaddress]$src,
    [Parameter(Mandatory=$true)][ipaddress]$dst,
    [Parameter(Mandatory=$false)][string]$svc = 'any'
    )

#Purpose is to obfuscate the password when user type his/her password.
$securepwd = Read-Host("Password") -AsSecureString
$bstrpwd = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($securepwd)
#Need to convert the password from secure to plaintext otherwise the encrypted cipher text will locked your account.
$pwd = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($bstrpwd)
