The following is a batch script authentication system. Your goal here is to get the batch script to authenticate you by inputting a password into the field.
@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET PRIME=2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101
SET CHARS=a b c d e f g h i j k l m n o p q r s t u v w x y z
SET PASSWORDVALUE=1
SET INPUT=
SET /P INPUT=Insert password:
IF "%INPUT%"=="" "%~0"
ECHO Authenticating...
:OVERLOOP
SET CURRENTPOSITION=0
:SUBLOOP
IF /I "!INPUT:~%CHARACTERPOSITION%,1!"=="!CHARS:~%CURRENTPOSITION%,1!" SET /A PASSWORDVALUE*=!PRIME:~%CURRENTPOSITION%,3!
SET /A CURRENTPOSITION+=3
IF NOT %CURRENTPOSITION%==78 GOTO :SUBLOOP
SET /A CHARACTERPOSITION+=1
IF NOT "!INPUT:~%CHARACTERPOSITION%,1!"=="" GOTO :OVERLOOP
:END
ENDLOCAL&IF NOT %PASSWORDVALUE%==1065435274 GOTO :ACCESSDENIED
ECHO You have been authenticated. Welcome aboard!
GOTO :SILENTPAUSE
:ACCESSDENIED
ECHO Access denied!
:SILENTPAUSE
PAUSE > NUL
Try to find the password..
If you find it.. Comment it..
If you don't.. Keep looking..
And yes, I know what is the password.
*COUGH*No I'm not giving any hint.*COUGH*
Good Luck [:<
