data empty afther encrypt/decrypt

[FMS 1]

Hello,

I think this is a simple question if you know the answer.

At this function i try to  (encrypt -> decrypt -> change -> encrypt ->decrypt->check ) an array.
This is a snippet from a larger script but the error is the same.
I do this encrypt decrypt action so i can save some setting along the way in a file.

But at the end (when i change the data and not when i dont change the data) is empty.

does somebody see what i'm doing wrong here?

thanks in advanced

Why are you converting the binary string returned by _Crypt_EncryptData to binary value when you try to decrypt it.  It is already a binary string, there is not need to use the Binary function.

This 

BinaryToString(_Crypt_DecryptData(Binary($encrypted_GL_USS_true[$i]), $GL_encr_key_settings, $CALG_AES_128))

should be

BinaryToString(_Crypt_DecryptData($encrypted_GL_USS_true[$i], $GL_encr_key_settings, $CALG_AES_128))

Now I've looked it over and it seems when you add +1 to the decrypted data, you convert to int instead of string and convert the binary return for a int with the value of 2, to a string.

So basically change:

$GL_array_decrypted_USS_settings[2] = $GL_array_decrypted_USS_settings[2] + "1"

To:

$GL_array_decrypted_USS_settings[2] = String( $GL_array_decrypted_USS_settings[2] + "1" )

Yes , that totaly was it  thanks
