Error encrypt/decrypt

[jeantje]

I have a problem when I encrypt a mp3 file with:

#include <String.au3>

$open = FileRead("mp3file.mp3")
$enc = _StringEncrypt(1, $open, "MP3FILE", 1)
FileWrite("mp3file.enc", $enc)

And decrypt it with

#include <String.au3>

$open = FileRead("mp3file.enc")
$enc = _StringEncrypt(0, $open, "MP3FILE", 1)
FileWrite("mp3file.mp3", $enc)

The file named mp3file.mp3 ends up as a 4 bytes file?

can anybody help me with this

The _StringEncrypt() function is for... strings. Binary data gets truncated at the first null byte, which would be EOF for a normal string. Look into the _Crypt* functions of the new Crypt.au3 UDF in the current Beta instead.
