This time, I only need a simple and fast obfuscation powershell encoder/decoder to avoid plain text password. I choose this simple solution:
I encode in decimal letter then I add 1
Ex: A = 41 (byte char in hexadecimal) = 65 (byte char in decimal)
obfuscation add 1 so obfuscation result = 65+1 = 66
obfuscation decoder sub 1 so 66-1 = 65 = A
((download scripts)
to encode
$strEncoded = ""
$strToEncode = "ABCD"
$strToEncode.ToCharArray() | Foreach { $strEncoded = $strEncoded + ([BYTE][CHAR]($_)+1) + " " }
Write-Host $strEncoded
encode result:
66 67 68 69
to decode
$strDecoded = ""
$strToDecode = "66 67 68 69"
$strToDecode.Trim().Split(" ") | Foreach { $strDecoded = $strDecoded + [CHAR][BYTE](($_)-1) }
Write-Host $strDecoded
decode result:
ABCD

$strComputername = Read-Host "Enter Computername"
$username = Read-Host "Enter Username"
$password = read-host "Enter a Password"
# To encode password
$strToEncode = $password
$strEncoded = ""
$strToEncode.ToCharArray() | Foreach { $strEncoded = $strEncoded + ([BYTE][CHAR]($_)+1) + " " }
$line = $strComputername + ";" + $username + ";" + $strEncoded
Write-Host $line
result with computer mycomputer, user myuser and password mypasswor;
Enter Computername: mycomputer Enter Username: myuser Enter a Password: mypassword mycomputer;myuser;110 122 113 98 116 116 120 112 115 101
Example of obfuscation decoder for your password
you need a test file servers.txt using line generated above
mycomputer;myuser;110 122 113 98 116 116 120 112 115 101 mycomputer2;myuser2;111 102 120 113 98 116 116 120 112 115 101
