Hi Marcus
Try this:
function CryptFile($hash, $filename)
{
// The key used is generated using another function.
// Since this function is only called once it has
// nothing to do with the performance of this function
$key = GenerateKey($hash);
$keylen = strlen($key =

Hi Marcus
Try this:
function CryptFile($hash, $filename)
{
// The key used is generated using another
Just to speed things up a little more...
* Thus wrote Marcel Tschopp:
...
$key = GenerateKey($hash);
$keylen = strlen($key = implode('', $key));
$handle = fopen($filename, 'r');
while (!feof($handle))
{
// Set the time limit or the script will time out

Wow! That REALLY did make a great difference!
Encoding a file of 2MB took 50 seconds before, now it is done in 1 (ONE)
second!
My Key is 8192 bytes long, is that the reason for why it so much faster
for me?
Most likely because the number crunching is
4 matches
