Imagine a case where some user should fire up a script. You can specify credentials in plain text. However in some cases you shouldn’t want this. You can shuffle letters a bit so that an user cannot see the plain text password. You shouldn’t use this for anything higer than a low profile user account. Let’s say this is a test case.

Shuffle letters from CHAR To BYTE:

$Data = "Welkom01"
$Data=[CHAR[]]$data
$Pass = @()
Foreach ($letter in $Data){
$Pass += ([BYTE][CHAR]"$letter") 
}
write-host $pass -Separator " " -NoNewline

This will output 87 101 108 107 111 109 48 49

Shuffle letters from BYTE To CHAR:

$Data = "87 101 108 107 111 109 48 49"
$Data = $Data.Split(" ")
$Pass = @()
Foreach ($Item in $data) {$Pass += ([CHAR][BYTE]"$Item")}

$pass -join""
