String Encrypt Problem

Recommended Posts

MadaraUchiha

Yo,

I use this script to encrypt my strings (Credits to Melba23):

#include <crypt.au3>

Global $MyStr = "Test Text"
_Crypt_Startup()
$hKey = _Crypt_DeriveKey("SomePassword", $CALG_RC4)

    ; Encrypt the name
    $bEncrypted = _Crypt_EncryptData($MyStr, $hKey, $CALG_USERKEY)
    ; And then decrypt it
    $bDecrypted = _Crypt_DecryptData($bEncrypted, $hKey, $CALG_USERKEY)
    ; And display the 2 results
    ConsoleWrite($bEncrypted & " - " & BinaryToString($bDecrypted) & @CRLF)

_Crypt_DestroyKey($hKey)
_Crypt_Shutdown()

This works perfectly on short strings. But I have a string which is about 40.000 characters long.

In this case the engine gives me an error:

C:UsersDomiDesktopEncryptionTest.au3 (3) : ==> Unterminated string.:

$MyStr = 'my very long string goes here...'

How can I solve this?

No problem here with my version.

#include <Constants.au3>
#include <Crypt.au3>

Example()

Func Example()
    Local $sData = ''
    For $i = 1 To 40000
        $sData &=  Chr(Random(65, 97, 1))
    Next

    ; Encrypt text using a generic password.
    Local $sEncrypted = StringEncrypt(True, $sData, 'securepassword')

    ; Display the encrypted text.
    MsgBox($MB_SYSTEMMODAL, '', StringLen($sEncrypted))

    ; Decrypt the encrypted text using the generic password.
    Local $sDecrypted = StringEncrypt(False, $sEncrypted, 'securepassword')

    ConsoleWrite('Debug: ' & ($sData == $sDecrypted) & @CRLF)
    ConsoleWrite($sDecrypted & @CRLF)
    ConsoleWrite($sData & @CRLF)

    ; Display the decrypted text.
    MsgBox($MB_SYSTEMMODAL, '', StringLen($sDecrypted))
EndFunc   ;==>Example

Func StringEncrypt($fEncrypt, $sData, $sPassword)
    _Crypt_Startup()
    Local $sReturn = ''
    If $fEncrypt Then
        $sReturn = _Crypt_EncryptData($sData, $sPassword, $CALG_RC4)
    Else
        $sReturn = BinaryToString(_Crypt_DecryptData($sData, $sPassword, $CALG_RC4))
    EndIf
    _Crypt_Shutdown()
    Return $sReturn
EndFunc   ;==>StringEncrypt
