What I meant was that if the encryption algorithm inserts some magic info
at the beginning o
Not at all cause the chunk are beeing free every time it is write in the
file.
so it does not excide the amount you set.

Ok tx
And you mean that I can concatenate every chunck in the same file ?
And what about decryption, could I take the same way ?

But if you encrypt one chunk at a time and concatenate them later, or if you
encrypt the whole thing, will you still get the same result?

function readfile_chunked ($filename) {
$chunksize = 1*(1024*1024); // it reads 1 mb per chunck. adjust this
if u need.
$buffer = '';
$handle = fopen($filename, 'rb');

There is no mcrypt function to load directly a file, so it's need to
preload it in a variable and then encrypt or decrypt it.
But when the file is 12M size it failed.

What do you mean "it failed"? What kind of error did you get?

well I have a big file (around 12M), and I have to encrypt this file,
and
to decrypt some time after.
How could I do? Is it possible to encrypt and decrypt a file line by
line ?

Start with the manual at http://us2.php.net/manual/en/ref.mcrypt.php
