How to replace middle chars with * in a string?

Question

I have the following

$builder = [System.Data.SqlClient.SqlConnectionStringBuilder]::New(\'Connection Timeout=120;User Id=UID1;Data Source=datasource.com;Passwor         


        

Answer 1

function Hide-ConnectionStringPassword {
    param(
       [parameter(Mandatory,ValueFromPipeline)]
       [System.Data.SqlClient.SqlConnectionStringBuilder]$ConnectionString
    )
    [string]$FistChar = $ConnectionString.Password[0]
    [string]$LastChar = $ConnectionString.Password[($ConnectionString.Password.Length - 1)]
    [string]$Stars = '*' * ($ConnectionString.Password.Length - 2)
    $ConnectionString.Password = $FistChar + $Stars + $LastChar 
    return $ConnectionString.ConnectionString
}

Hide-ConnectionStringPassword 'Connection Timeout=120;User Id=UID1;Data Source=datasource.com;Password=password12!553;'

outputs:

Data Source=datasource.com;User ID=UID1;Password=p************3;Connect Timeout=120
