One more thing. You cannot encrypt/decrypt photos. Try to open files binary and then encrypt/decrypt.

AND THIS IS THE LIMIT OF OF SCRIPT, ITS JUST TOOOOO SLOW!!

I will try to make a Delphi version or MASM32

and is there anyway to use asm in autoit??

For text documents I write a simple cipher, maybe you can inspire for the future encryption system.

Func FilterXOR($STRING,$NUM=5)
    Local $INDEX,$RESULT=""
    For $INDEX = 1 To StringLen($STRING)
        $RESULT &= Chr(BitXOR(Asc(StringMid($STRING,$INDEX,1)),$NUM))
    Next
    Return $RESULT
EndFunc

Func Cipher($DATA,$PASSWORD,$OPT=0)
    Local $INDEX,$RESULT="",$L1,$L2,$CARRY,$PWD
    $L1 = StringLen($DATA)
    $L2 = StringLen($PASSWORD)
    If $L1 < $L2 Then SetError(1,0,0)
    $CARRY = Mod($L1,$L2)
    For $INDEX = 1 To Int($L1/$L2)
        $PWD &= $PASSWORD
    Next
    $PWD &= StringLeft($PASSWORD,$CARRY)
    For $INDEX = 1 To $L1
        If $OPT = 0 Then
            $RESULT &= Chr(Asc(StringMid($DATA,$INDEX,1))+Asc(StringMid($PWD,$INDEX,1)))
        ElseIf $OPT = 1 Then
            $RESULT &= Chr(Asc(StringMid($DATA,$INDEX,1))-Asc(StringMid($PWD,$INDEX,1)))
        EndIf
        GUICtrlSetData($PROGRESS,$INDEX*100/$L1)
    Next
    Return $RESULT
EndFunc

$GUI = GUICreate("File Encrypt/Decrypt",300,150,-1,-1)
$OPEN = GUICtrlCreateInput(@ScriptDir,5,5,250,20)
$B1 = GUICtrlCreateButton("..",270,5,20,20)

Its very nice but I have to say its very very weak(Sorry) encryption that password 111 and 1111 is the same

the password 111 and 112 give some of the text out

This is very weak because you can randomly generate a password about 1000 of them and take the char that is the most common of everyone of them and you will get the original text, then after that you can use the different to generate the password

--------------------------------------------------------------------------------------------------------------------------

I also change from 54BIT key to 216BIT key in DSCV3 and remove the signature thing

Test file for DSCV2 is here http://skypower.axspace.com/DSCV2/test.ntxt

Have not generate DSCV3 Test file yet

Here is a test result for your encryption

http://skypower.axspace.com/aaa2.txt

In DSCV3 can encrypt text file and the size is less(the same as original thanks to you)

I think DSCV3 is very secure, much more than RC4(A LOT) that its originally from

UPDATED DSCV3 and sorry i used your gui if you dont like it I will remove it

I know that is not a very strong encryption. I use only for some not important data. Exemple: Encrypt data send from server to client. If you want some very strong I saw on forum implementation in autoit for Blowfish,Rijndael. :)
